VNF Modeling Requirements
=========================
TOSCA YAML
----------
Introduction
^^^^^^^^^^^^^^
This reference document is the VNF TOSCA Template Requirements for
ONAP, which provides recommendations and standards for building VNF
TOSCA templates compatible with ONAP initial implementations of
Network Cloud. It has the following features:
1. VNF TOSCA template designer supports GUI and CLI.
2. VNF TOSCA template is aligned to the newest TOSCA protocol, “Working
Draft 04-Revision 06”.
3. VNF TOSCA template supports HPA features, such as NUMA, Hyper
Threading, SRIOV, etc.
Intended Audience
^^^^^^^^^^^^^^^^^^
This document is intended for persons developing VNF TOSCA templates
that will be orchestrated by ONAP.
Scope
^^^^^^^^^^^^^^^^
ONAP implementations of Network Cloud supports TOSCA Templates, also
referred to as TOSCA in this document.
ONAP requires the TOSCA Templates to follow a specific format. This
document provides the mandatory, recommended, and optional requirements
associated with this format.
Overview
^^^^^^^^^^^^^^^^
The document includes three charters to help the VNF providers to use the
VNF model design tools and understand the VNF package structure and VNF
TOSCA templates.
In the ONAP, VNF Package and VNFD template can be designed by manually
or via model designer tools. VNF model designer tools can provide the
GUI and CLI tools for the VNF provider to develop the VNF Package and VNFD
template.
The VNF package structure is align to the NFV TOSCA protocol, and
supports CSAR
The VNFD and VNF package are all align to the NFV TOSCA protocol, which
supports multiple TOSCA template yaml files, and also supports
self-defined node or other extensions.
NFV TOSCA Template
^^^^^^^^^^^^^^^^^^^^
TOSCA templates supported by ONAP must follow the requirements
enumerated in this section.
TOSCA Introduction
^^^^^^^^^^^^^^^^^^^
TOSCA defines a Meta model for defining IT services. This Meta model
defines both the structure of a service as well as how to manage it. A
Topology Template (also referred to as the topology model of a service)
defines the structure of a service. Plans define the process models that
are used to create and terminate a service as well as to manage a
service during its whole lifetime.
A Topology Template consists of a set of Node Templates and Relationship
Templates that together define the topology model of a service as a (not
necessarily connected) directed graph. A node in this graph is
represented by a *Node Template*. A Node Template specifies the
occurrence of a Node Type as a component of a service. A *Node Type*
defines the properties of such a component (via *Node Type Properties*)
and the operations (via *Interfaces*) available to manipulate the
component. Node Types are defined separately for reuse purposes and a
Node Template references a Node Type and adds usage constraints, such as
how many times the component can occur.

TOSCA Modeling Principles & Data Model
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This section describing TOSCA modeling principles and data model for
NFV, which shall be based on [TOSCA-1.0] and [TOSCA-Simple-Profile-YAML
V1.0], or new type based on ETSI NFV requirements, etc.
VNF Descriptor Template
^^^^^^^^^^^^^^^^^^^^^^^^^
The VNF Descriptor (VNFD) describes the topology of the VNF by means of
ETSI NFV IFA011 [IFA011] terms such as VDUs, Connection Points, Virtual
Links, External Connection Points, Scaling Aspects, Instantiation Levels
and Deployment Flavours.
The VNFD (VNF Descriptor) is read by both the NFVO and the VNFM. It
represents the contract & interface of a VNF and ensures the
interoperability across the NFV functional blocks.
The main parts of the VNFD are the following:
- VNF topology: it is modeled in a cloud agnostic way using virtualized
containers and their connectivity. Virtual Deployment Units (VDU)
describe the capabilities of the virtualized containers, such as
virtual CPU, RAM, disks; their connectivity is modeled with VDU
Connection Point Descriptors (VduCpd), Virtual Link Descriptors (Vld)
and VNF External Connection Point Descriptors (VnfExternalCpd);
- VNF deployment aspects: they are described in one or more deployment
flavours, including instantiation levels, supported LCM operations,
VNF LCM operation configuration parameters, placement constraints
(affinity / antiaffinity), minimum and maximum VDU instance numbers,
and scaling aspect for horizontal scaling.
The following table defines the TOSCA Type “derived from” values that
SHALL be used when using the TOSCA Simple Profile for NFV version 1.0
specification [TOSCA-Simple-Profile-NFV-v1.0] for NFV VNFD with aggreed
changes from ETSI SOL001 draft.

General Guidelines
^^^^^^^^^^^^^^^^^^
This section contains general Heat Orchestration Template guidelines.
YAML Format
~~~~~~~~~~~
R-95303 A VNF's Heat Orchestration Template **MUST** be defined using valid YAML.
YAML (YAML Ain't
Markup Language) is a human friendly data serialization standard for all
programming languages. See http://www.yaml.org/.
Heat Orchestration Template Format
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
As stated above, Heat Orchestration templates must be defined in YAML.
YAML rules include:
- Tabs are not allowed, use spaces ONLY
- You must indent your properties and lists with 1 or more spaces
- All Resource IDs and resource property parameters are case-sensitive. (e.g., "ThIs", is not the same as "thiS")
Heat Orchestration Template Structure
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Heat Orchestration template structure follows the following format,
as defined by OpenStack at
https://docs.openstack.org/developer/heat/template_guide/hot_spec.html
.. code-block:: python
heat_template_version: <date>
description:
# a description of the template
parameter_groups:
# a declaration of input parameter groups and order
parameters:
# declaration of input parameters
resources:
# declaration of template resources
outputs:
# declaration of output parameters
conditions:
# declaration of conditions
heat_template_version
+++++++++++++++++++++
R-27078 A VNF's Heat Orchestration template **MUST** contain
the section "heat_template_version:".
The section "heat_template_version:" must be set to a date
that is supported by the OpenStack environment.
description
+++++++++++
R-39402 A VNF's Heat Orchestration Template **MUST**
contain the section "description:".
parameter_groups
++++++++++++++++
A VNF Heat Orchestration template may
contain the section "parameter_groups:".
parameters
++++++++++
R-35414 A VNF Heat Orchestration's template **MUST**
contain the section "parameters:".
.. code-block:: python
parameters:
<param name>:
type: <string | number | json | comma_delimited_list | boolean>
label: <human-readable name of the parameter>
description: <description of the parameter>
default: <default value for parameter>
hidden: <true | false>
constraints:
<parameter constraints>
immutable: <true | false>
This section allows for
specifying input parameters that have to be provided when instantiating
the template. Each parameter is specified in a separate nested block
with the name of the parameters defined in the first line and additional
attributes (e.g., type, label) defined as nested elements.
R-90279 A VNF Heat Orchestration's template's parameter **MUST**
be used in a resource with the exception of the parameters
for the OS::Nova::Server resource property availability_zone.
R-91273 A VNF Heat Orchestration’s template’s parameter for
the OS::Nova::Server resource property availability_zone
**MAY NOT** be used in any OS::Nova::Resource.
<param name>
____________
The name of the parameter.
R-25877 A VNF's Heat Orchestration Template's parameter
name (i.e., <param name>) **MUST** contain only
alphanumeric characters and underscores ('_').
type
____
R-36772 A VNF’s Heat Orchestration Template’s parameter
**MUST** include the attribute “type:”.
R-11441 A VNF’s Heat Orchestration Template’s parameter
type **MUST** be one of the following values: "string",
"number", "json", "comma_delimited_list" or "boolean".
label
_____
R-32094 A VNF's Heat Orchestration Template parameter
declaration **MAY** contain the attribute "label:"
description
___________
R-44001 A VNF's Heat Orchestration Template parameter
declaration **MUST** contain the attribute "description".
Note that the parameter attribute “description:” is an
OpenStack optional attribute that provides a description
of the parameter. ONAP implementation requires this attribute.
default
_______
R-90526 A VNF Heat Orchestration Template parameter
declaration **MUST** not contain the default attribute.
R-26124 If a VNF Heat Orchestration Template parameter
requires a default value, it **MUST** be enumerated in the environment file.
Note that the parameter attribute “default:” is an OpenStack
optional attribute that declares the default value of the
parameter. ONAP implementation prohibits the use of this attribute.
hidden
______
R-32557 A VNF's Heat Orchestration Template parameter
declaration MAY contain the attribute "hidden:".
The parameter attribute "hidden:" is an OpenStack optional
attribute that defines whether the parameters should be
hidden when a user requests information about a stack
created from the template. This attribute can be used
to hide passwords specified as parameters.
constraints
___________
The parameter attribute "constraints:" is an OpenStack optional
attribute that defines a list of constraints to apply to the parameter.
R-88863 A VNF's Heat Orchestration Template's parameter defined as
type "number" **MUST** have a parameter constraint of "range" or
"allowed_values" defined.
R-40518 A VNF's Heat Orchestration Template’s parameter defined as
type "string" **MAY** have a parameter constraint defined.
R-96227 A VNF's Heat Orchestration Template’s parameter defined as
type "json" **MAY** have a parameter constraint defined.
R-79817 A VNF's Heat Orchestration Template’s parameter defined as
type "comma_delimited_list" **MAY** have a parameter constraint defined.
R-06613 A VNF's Heat Orchestration Template’s parameter defined as
type "boolean" **MAY** have a parameter constraint defined.
R-00011 A VNF's Heat Orchestration Template's Nested YAML files
parameter's **MUST NOT** have a parameter constraint defined.
The constraints block of a parameter definition defines additional
validation constraints that apply to the value of the parameter.
The parameter values provided in the VNF Heat Orchestration Template
are validated against the constraints at instantiation time.
The stack creation fails if the parameter value doesn’t comply to the constraints.
The constraints are defined as a list with the following syntax
.. code-block:: python
constraints:
<constraint type>: <constraint definition>
description: <constraint description>
..
**<constraint type>** Provides the type of constraint to apply.
The list of OpenStack supported constraints can be found at
https://docs.openstack.org/heat/latest/template_guide/hot_spec.html .
**<constraint definition>** provides the actual constraint.
The syntax and constraint is dependent of the <constraint type> used.
**description** is an optional attribute that provides a description of the
constraint. The text is presented to the user when the value the user
defines violates the constraint. If omitted, a default validation
message is presented to the user.
Below is a brief overview of the "range" and "allowed values" constraints.
For complete details on constraints, see
https://docs.openstack.org/heat/latest/template_guide/hot_spec.html#parameter-constraints
**range**
range: The range constraint applies to parameters of type: number.
It defines a lower and upper limit for the numeric value of the
parameter. The syntax of the range constraint is
.. code-block:: python
range: { min: <lower limit>, max: <upper limit> }
..
It is possible to define a range constraint with only a lower
limit or an upper limit.
**allowed_values**
allowed_values: The allowed_values constraint applies to parameters of
type \"string\" or type \"number\". It specifies a set of possible
values for a parameter. At deployment time, the user-provided value
for the respective parameter must match one of the elements of the
list. The syntax of the allowed_values constraint is
.. code-block:: python
allowed_values: [ <value>, <value>, ... ]
Alternatively, the following YAML list notation can be used
allowed_values:
- <value>
- <value>
- ...
. .
immutable
_________
R-22589 A VNF’s Heat Orchestration Template parameter declaration
**MAY** contain the attribute "immutable:".
The parameter attribute \"immutable:\" is an OpenStack optional
attribute that defines whether the parameter is updatable. A Heat
Orchestration Template stack update fails if immutable is set to
true and the parameter value is changed. This attribute
\"immutable:\" defaults to false.
resources
+++++++++
R-23664 A VNF's Heat Orchestration template **MUST** contain
the section "resources:".
R-90152 A VNF's Heat Orchestration Template's "resources:"
section **MUST** contain the declaration of at least one resource.
R-40551 A VNF's Heat Orchestration Template's Nested YAML files
**MAY** contain the section "resources:".
Each resource is defined as a
separate block in the resources section with the following syntax.
.. code-block:: python
resources:
<resource ID>:
type: <resource type>
properties:
<property name>: <property value>
metadata:
<resource specific metadata>
depends_on: <resource ID or list of ID>
update_policy: <update policy>
deletion_policy: <deletion policy>
external_id: <external resource ID>
condition: <condition name or expression or boolean>
resource ID
___________
R-75141 A VNF's Heat Orchestration Template's resource name
(i.e., <resource ID>) **MUST** only contain alphanumeric
characters and underscores ('_').
R-16447 A VNF's <resource ID> **MUST** be unique across all
Heat Orchestration Templates and all HEAT Orchestration Template
Nested YAML files that are used to create the VNF.
Note that a VNF can be composed of one or more Heat Orchestration Templates.
Note that OpenStack requires the <resource ID> to be unique to the
Heat Orchestration Template and not unique across all Heat
Orchestration Templates the compose the VNF.
type
____
The resource attribute \"type:\" is an OpenStack required
attribute that defines the resource type, such as
OS::Nova::Server or OS::Neutron::Port.
The resource attribute \"type:\" may specify a VNF HEAT
Orchestration Template Nested YAML file.
R-53952 A VNF’s Heat Orchestration Template’s Resource
**MUST NOT** reference a HTTP-based resource definitions.
R-71699 A VNF’s Heat Orchestration Template’s Resource
**MUST NOT** reference a HTTP-based Nested YAML file.
properties
__________
The resource attribute \"properties:\" is an OpenStack optional
attribute that provides a list of resource-specific properties.
The property value can be provided in place, or via a function
(e.g., `Intrinsic functions <https://docs.openstack.org/developer/heat/template_guide/hot_spec.html#hot-spec-intrinsic-functions>`__).
R-10834 If a VNF Heat Orchestration Template resource attribute
"property:" uses a nested "get_param", one level of nesting is
supported and the nested "get_param" **MUST** reference an index
metadata
________
The resource attribute \"metadata:\" is an OpenStack optional attribute.
R-97199 A VNF's Heat Orchestration Template's OS::Nova::Server
resource **MUST** contain the attribute "metadata".
Section 5.4 contains the OS::Nova::Server mandatory and optional metadata.
depends_on
__________
The resource attribute \"depends_on:\" is an OpenStack optional
attribute.
See `OpenStack documentation <https://docs.openstack.org/developer/heat/template_guide/hot_spec.html#hot-spec-resources-dependencies>`__
for additional details.
R-46968 VNF’s Heat Orchestration Template’s Resource **MAY**
declare the attribute “depends_on:”.
update_policy
_____________
R-63137 VNF’s Heat Orchestration Template’s Resource **MAY**
declare the attribute “update_policy:”.
deletion_policy
_______________
R-43740 A VNF’s Heat Orchestration Template’s Resource
**MAY** declare the attribute “deletion_policy:”.
If specified, the \"deletion_policy:\" attribute for resources
allows values 'Delete', 'Retain', and 'Snapshot'.
Starting with heat_template_version 2016-10-14, lowercase
equivalents are also allowed.
The default policy is to delete the physical resource when
deleting a resource from the stack.
external_id
___________
R-78569 A VNF’s Heat Orchestration Template’s Resouce **MAY**
declare the attribute “external_id:”.
This attribute allows for specifying the resource_id for an
existing external (to the stack) resource. External resources
cannot depend on other resources, but we allow other resources to
depend on external resource. This attribute is optional.
Note: when this is specified, properties will not be used for
building the resource and the resource is not managed by Heat.
This is not possible to update that attribute. Also,
resource won’t be deleted by heat when stack is deleted.
condition
_________
The resource attribute \"condition:\" is an OpenStack optional attribute.
Support for the resource condition attribute was added
in the Newton release of OpenStack.
outputs
+++++++
R-36982 A VNF’s Heat Orchestration template **MAY** contain the “outputs:” section.
This section allows for specifying output parameters
available to users once the template has been instantiated. If the
section is specified, it will need to adhere to specific requirements.
See `ONAP Parameter Classifications Overview`_ and
`ONAP Output Parameter Names`_ for additional details.
Environment File Format
~~~~~~~~~~~~~~~~~~~~~~~
The environment file is a yaml text file.
(https://docs.openstack.org/developer/heat/template_guide/environment.html)
R-86285 The VNF Heat Orchestration Template **MUST** have a corresponding
environment file, even if no parameters are required to be enumerated.
The use of an environment file in OpenStack is optional.
In ONAP, it is mandatory.
R-03324 The VNF Heat Orchestration Template **MUST** contain the
"parameters" section in the
environment file
R-68198 A VNF’s Heat Orchestration template’s Environment File’s
“parameters:” section **MAY** enumerate parameters.
ONAP implementation requires the parameters section in the
environmental file to be declared. The parameters section
contains a list of key/value pairs.
R-59930 A VNF’s Heat Orchestration template’s Environment
File’s **MAY** contain the “parameter_defaults:” section.
The “parameter_defaults:” section contains default parameters
that are passed to all template resources.
R-46096 A VNF’s Heat Orchestration template’s Environment File’s
**MAY** contain the “encrypted_parameters:” section.
The “encrypted_parameters:” section contains a list of encrypted parameters.
R-24893 A VNF’s Heat Orchestration template’s Environment File’s
**MAY** contain the “event_sinks:” section.
The “event_sinks:” section contains the list of endpoints that would
receive stack events.
R-42685 A VNF’s Heat Orchestration template’s Environment File’s
**MAY** contain the “parameter_merge_strategies:” section.
The “parameter_merge_strategies:” section provides the merge strategies
for merging parameters and parameter defaults from the environment file.
R-67231 A VNF’s Heat Orchestration template’s Environment File’s **MUST NOT**
contain the “resource_registry:” section.
ONAP implementation does not support the Environment File resource_registry
section. The resource_registry section allows for the definition of custom resources.
SDC Treatment of Environment Files
++++++++++++++++++++++++++++++++++
Parameter values enumerated in the environment file are used by SDC as
the default value. However, the SDC user may use the SDC GUI to
overwrite the default values in the environment file.
SDC generates a new environment file for distribution to MSO based on
the uploaded environment file and the user provided GUI updates. The
user uploaded environment file is discarded when the new file is
created.
ONAP has requirements for what parameters must be enumerated in the
environment file and what parameter must not be enumerated in the
environment file. See `ONAP Parameter Classifications Overview`_ and
`ONAP Resource ID and Parameter Naming Convention`_ for more details.
ONAP Heat Orchestration Templates: Overview
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ONAP supports a modular Heat Orchestration Template design pattern,
referred to as *VNF Modularity.*
ONAP VNF Modularity Overview
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
R-69663 A VNF **MAY** be composed from one or more Heat Orchestration
Templates, each of which represents a subset of the overall VNF.
The Heat Orchestration Templates can be thought of a components or
modules of the VNF and are referred to as “\ *VNF Modules*\ ”.
During orchestration, these modules are
deployed incrementally to create the complete VNF.
R-33132 A VNF’s Heat Orchestration Template **MAY** be 1.) Base Module
Heat Orchestration Template (also referred to as a Base Module), 2.)
Incremental Module Heat Orchestration Template (referred to as an Incremental
Module), or 3.) a Cinder Volume Module Heat Orchestration Template
(referred to as Cinder Volume Module).
R-37028 The VNF **MUST** be composed of one “base” module.
R-13196 A VNF **MAY** be composed of zero to many Incremental Modules
R-20974 The VNF **MUST** deploy the base module first, prior to
the incremental modules.
R-28980 A VNF’s incremental module **MAY** be used for initial VNF
deployment only.
R-86926 A VNF’s incremental module **MAY** be used for scale out only.
A VNF’s Incremental Module that is used for scale out is deployed
sometime after initial VNF deployment to add capacity.
R-91497 A VNF’s incremental module **MAY** be used for both deployment
and scale out.
R-68122 A VNF’s incremental module **MAY** be deployed more than once,
either during initial VNF deployment and/or scale out.
R-46119 A VNF’s Heat Orchestration Template’s Resource OS::Heat::CinderVolume
**MAY** be defined in a Base Module.
R-90748 A VNF’s Heat Orchestration Template’s Resource OS::Cinder::Volume
**MAY** be defined in an Incremental Module.
R-03251 A VNF’s Heat Orchestration Template’s Resource OS::Cinder::Volume
**MAY** be defined in a Cinder Volume Module.
ONAP also supports the concept of an optional, independently deployed Cinder
volume via a separate Heat Orchestration Templates, referred to as a Cinder
Volume Module. This allows the volume to persist after a Virtual Machine
(VM) (i.e., OS::Nova::Server) is deleted, allowing the volume to be reused
on another instance (e.g., during a failover activity).
R-11200 The VNF **MUST** keep the scope of a Cinder volume module, when it
exists, to be 1:1 with the VNF Base Module or Incremental Module
It is strongly recommended that Cinder Volumes be created in a Cinder Volume
Module.
R-38474 The VNF **MUST** have a corresponding environment file for a
Base Module.
R-81725 The VNF **MUST** have a corresponding environment file for an
Incremental Module.
R-53433 The VNF **MUST** have a corresponding environment file for a
Cinder Volume Module.
These concepts will be described in more detail throughout the document.
This overview is provided to set the stage and help clarify the concepts
that will be introduced.
Nested Heat Orchestration Templates Overview
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP supports nested Heat Orchestration Templates per OpenStack
specifications.
R-36582 A VNF’s Base Module **MAY** utilize nested heat.
R-56721 A VNF’s Incremental Module **MAY** utilize nested heat.
R-30395 A VNF’s Cinder Volume Module **MAY** utilize nested heat.
Nested templates may be suitable for larger VNFs that contain many
repeated instances of the same VM type(s). A common usage pattern is to
create a nested template for each VM type along with its supporting
resources. The Heat Orchestration Template may then reference these
nested templates either statically (by repeated definition) or
dynamically (via OS::Heat::ResourceGroup).
See `Nested Heat Templates`_ for additional details.
ONAP Heat Orchestration Template Filenames
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to enable ONAP to understand the relationship between Heat
files, the following Heat file naming convention must be utilized.
In the examples below, <text> represents any alphanumeric string that
must not contain any special characters and must not contain the word
“base”.
R-87485 A VNF’s Heat Orchestration Template’s file extension **MUST**
be in the lower case format ‘.yaml’ or ‘.yml’.
R-56438 A VNF’s Heat Orchestration Template’s Nested YAML file extension
**MUST** be in the lower case format ‘.yaml’ or ‘.yml’.
R-74304 A VNF’s Heat Orchestration Template’s Environment file extension
**MUST** be in the lower case format ‘.env’.
Base Modules
++++++++++++
R-81339 A VNF Heat Orchestration Template’s Base Module file name **MUST**
include ‘base’ in the filename and **MUST** match one of the following four
formats: 1.) ‘base_<text>.y[a]ml’, 2.) ‘<text>_base.y[a]ml’, 3.)
‘base.y[a]ml’, or 4.) ‘<text>_base_<text>’.y[a]ml; where ‘base’ is case
insensitive and where ‘<text>’ **MUST** contain only alphanumeric characters
and underscores ‘_’ and **MUST NOT** contain the case insensitive word ‘base’.
R-91342 A VNF Heat Orchestration Template’s Base Module’s Environment File
**MUST** be named identical to the VNF Heat Orchestration Template’s Base
Module with ‘.y[a]ml’ replaced with ‘.env’.
Incremental Modules
+++++++++++++++++++
R-87247 A VNF Heat Orchestration Template’s Incremental Module file name
**MUST** contain only alphanumeric characters and underscores ‘_’ and
**MUST NOT** contain the case insensitive word ‘base’.
R-94509 A VNF Heat Orchestration Template’s Incremental Module’s Environment
File **MUST** be named identical to the VNF Heat Orchestration Template’s
Incremental Module with ‘.y[a]ml’ replaced with ‘.env’.
To clearly identify the incremental module, it is recommended to use the
following naming options for modules:
- module_<text>.y[a]ml
- <text>_module.y[a]ml
- module.y[a]ml
- <text>_module_<text>.y[a]ml
Cinder Volume Modules
+++++++++++++++++++++
R-82732 A VNF Heat Orchestration Template’s Cinder Volume Module **MUST** be
named identical to the base or incremental module it is supporting with
‘_volume appended’
R-31141 A VNF Heat Orchestration Template’s Cinder Volume Module’s Environment
File **MUST** be named identical to the VNF Heat Orchestration Template’s
Cinder Volume Module with .y[a]ml replaced with ‘.env’.
Nested Heat file
++++++++++++++++
R-76057 A VNF Heat Orchestration Template’s Nested YAML file name **MUST**
contain only alphanumeric characters and underscores ‘_’ and **MUST NOT**
contain the case insensitive word ‘base’.
Examples include
- <text>.y[a]ml
- nest_<text>.y[a]ml
- <text>_nest.y[a]ml
- nest.y[a]ml
- <text>_nest_<text>.y[a]ml
VNF Heat Orchestration Template's Nested YAML file does not have a
corresponding environment files, per OpenStack specifications.
R-18224 The VNF Heat Orchestration Template **MUST** pass in as properties
all parameter values
associated with the nested heat file in the resource definition defined
in the parent heat template.
Output Parameters
~~~~~~~~~~~~~~~~~
The output parameters are parameters defined in the output section of a
Heat Orchestration Template. The ONAP output parameters are subdivided
into three categories:
1. ONAP Base Module Output Parameters
2. ONAP Volume Module Output Parameters
3. ONAP Predefined Output Parameters.
ONAP Base Module Output Parameters
++++++++++++++++++++++++++++++++++++
ONAP Base Module Output Parameters are declared in the 'outputs:'' section of
the VNF's Heat Orchestration Template's Base Module. A Base Module Output
Parameter is available as an input parameter (i.e., declared in the
'parameters:'' section) to all Incremental Modules in the VNF.
A Base Module Output Parameter may be used as an input parameter in any
incremental module in the VNF. Note that the parameter is not
available to other VNFs.
R-52753 VNF’s Heat Orchestration Template’s Base Module’s output parameter’s
name and type **MUST** match the VNF’s Heat Orchestration Template’s
incremental Module’s name and type unless the output parameter is of type
‘comma_delimited_list’, then the corresponding input parameter **MUST**
be declared as type ‘json’.
If the Output parameter has a comma_delimited_list value (e.g., a collection
of UUIDs from a Resource Group), then the corresponding input parameter
must be declared as type json and not a comma_delimited_list, which is
actually a string value with embedded commas.
R-22608 When a VNF’s Heat Orchestration Template’s Base Module’s output
parameter is declared as an input parameter in an Incremental Module,
the parameter attribute ‘constraints:’ **MUST NOT** be declared.
Additional details on ONAP Base Module Output Parameters are provided in
`ONAP Output Parameter Names`_ and ONAP VNF Modularity.
ONAP Volume Module Output Parameters
++++++++++++++++++++++++++++++++++++
R-89913 A VNF’s Heat Orchestration Template’s Cinder Volume Module Output
Parameter(s) **MUST** include the UUID(s) of the Cinder Volumes created in
template, while other Output Parameters **MAY** be included.
A VNF’s Heat Orchestration Template’s Cinder Volume Module Output Parameter(s)
are only available for the module (base or incremental) that the volume
template is associated with.
R-07443 A VNF’s Heat Orchestration Templates’ Cinder Volume Module Output
Parameter’s name and type **MUST** match the input parameter name and type
in the corresponding Base Module or Incremental Module unless the Output
Parameter is of the type ‘comma_delimited_list’, then the corresponding input
parameter **MUST** be declared as type ‘json’.
If the Output parameter has a comma_delimited_list value (e.g., a collection
of UUIDs from a Resource Group), then the corresponding input parameter must
be declared as type json and not a comma_delimited_list, which is actually a
string value with embedded commas.
R-20547 When an ONAP Volume Module Output Parameter is declared as an input
parameter in a base or an incremental module Heat Orchestration Template,
parameter constraints **MUST NOT** be declared.
Additional details on ONAP Base Module Output Parameters are provided in
`ONAP Output Parameter Names`_ and `Cinder Volume Templates`_.
ONAP Predefined Output Parameters
+++++++++++++++++++++++++++++++++++
ONAP will look for a small set of pre-defined Heat output parameters to
capture resource attributes for inventory in ONAP. These output parameters
are optional and currently only two parameters are supported. These output
parameters are optional and are specified in `OAM Management IP Addresses`_.
Support of heat stack update
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP does not support the use of heat stack-update command for scaling
(growth/de-growth).
R-39349 A VNF Heat Orchestration Template **MUST NOT** be designed to
utilize the OpenStack ‘heat stack-update’ command for scaling
(growth/de-growth).
R-43413 A VNF **MUST** utilize a modular Heat Orchestration Template
design to support scaling (growth/de-growth).
Scope of a Heat Orchestration Template
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
R-59482 A VNF’s Heat Orchestration Template **MUST NOT** be VNF instance
specific or Cloud site specific
R-56750 A VNF’s Heat Orchestration Template’s parameter values that are
constant across all deployments **MUST** be declared in a Heat Orchestration
Template Environment File.
ONAP provides the instance specific parameter values to the Heat
Orchestration Template at orchestration time.
R-01896 A VNF’s Heat Orchestration Template’s parameter values that are
constant across all deployments **MUST** be declared in a Heat Orchestration
Template Environment File.
Networking
^^^^^^^^^^
ONAP defines two types of networks: External Networks and Internal Networks.
External Networks
~~~~~~~~~~~~~~~~~
ONAP defines an external network in relation to the VNF and not with regard
to the Network Cloud site. External networks may also be referred to as
“inter-VNF” networks. An external network must connect VMs in a VNF to
VMs in another VNF or an external gateway or external router.
An External Network may be a Neutron Network or a Contrail Network.
R-16968 A VNF’s Heat Orchestration Templates **MUST NOT** include heat
resources to create external networks.
External networks must be orchestrated separately, independent of the VNF.
This allows the network to be shared by multiple VNFs and managed
independently of VNFs.
R-00606 A VNF **MAY** be connected to zero, one or more than one external
networks.
R-57424 A VNF’s port connected to an external network **MUST** connect the
port to VMs in another VNF and/or an external gateway and/or external router.
R-29865 A VNF’s port connected to an external network **MUST NOT** connect
the port to VMs in the same VNF.
R-69014 When a VNF connects to an external network, a network role, referred
to as the ‘{network-role}’ **MUST** be assigned to the external network
for use in the VNF’s Heat Orchestration Template.
R-05201 When a VNF connects to two or more external networks, each external
network **MUST** be assigned a unique ‘{network-role}’ in the context of
the VNF for use in the VNF’s Heat Orchestration Template.
R-83015 A VNF’s ‘{network-role}’ assigned to an external network **MUST**
be different than the ‘{network-role}’ assigned to the VNF’s internal
networks, if internal networks exist.
ONAP enforces a naming convention for parameters associated with
external networks. `ONAP Resource ID and Parameter Naming Convention`_
provides additional details.
Internal Networks
~~~~~~~~~~~~~~~~~
ONAP defines an internal network in relation to the VNF and not with
regard to the Network Cloud site. Internal networks may also be referred
to as “intra-VNF” networks or “private” networks. An internal network
only connects VMs in a single VNF; it must not connect to other VNFs
or an external gateway or router
R-87096 A VNF **MAY** contain zero, one or more than one internal networks.
R-35666 If a VNF has an internal network, the VNF Heat Orchestration
Template **MUST** include the heat resources to create the internal network.
R-86972 A VNF **SHOULD** create the internal network in the VNF’s Heat
Orchestration Template Base Module.
An Internal Network may be created using Neutron Heat Resources and/or
Contrail Heat Resources.
R-52425 A VNF’s port connected to an internal network **MUST** connect
the port to VMs in the same VNF.
R-46461 A VNF’s port connected to an internal network **MUST NOT** connect
the port to VMs in another VNF and/or an external gateway and/or
external router.
R-68936 When a VNF creates an internal network, a network role, referred to
as the ‘{network-role}’ **MUST** be assigned to the internal network for
use in the VNF’s Heat Orchestration Template.
R-32025 When a VNF creates two or more internal networks, each internal
network **MUST** be assigned a unique ‘{network-role}’ in the context of
the VNF for use in the VNF’s Heat Orchestration Template.
R-69874 A VNF’s ‘{network-role}’ assigned to an internal network **MUST**
be different than the ‘{network-role}’ assigned to the VNF’s external
networks.
R-34726 If a VNF’s port is connected to an internal network and the port
is created in the same Heat Orchestration Template as the internal network,
then the port resource **MUST** use a ‘get_resource’ to obtain
the network UUID.
R-22688 If a VNF’s port is connected to an internal network and the
port is created in an Incremental Module and the internal network is created
in the Base Module then the UUID of the internal network **MUST** be exposed
as a parameter in the ‘outputs:’ section of the Base Module and the port
resource **MUST** use a ‘get_param’ to obtain the network UUID.
ONAP does not programmatically enforce a naming convention for
parameters for internal network. However, a naming convention is
provided that must be followed.
`ONAP Resource ID and Parameter Naming Convention`_
provides additional details.
ONAP Resource ID and Parameter Naming Convention
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This section provides the ONAP naming requirements for
1. Resource IDs
2. Resource Property Parameters
{vm-type}
~~~~~~~~~
R-01455 When a VNF's Heat Orchestration Template creates a Virtual Machine (i.e., 'OS::Nova::Server'),
each 'class' of VMs **MUST** be assigned a VNF unique
'{vm-type}'; where 'class' defines VMs that **MUST** have the following
identical characteristics:
1.) OS::Nova::Server property flavor value
2.) OS::Nova::Server property image value
3.) Cinder Volume attachments
- Each VM in the 'class' **MUST** have the identical Cinder Volume
configuration
4.) Network attachments and IP address requirements
- Each VM in the 'class' **MUST** have the the identical number
of ports connecting to the identical networks and requiring the
identical IP address configuration.
R-82481 A VNF's Heat Orchestration Template's Resource property
parameter that is
associated with a unique Virtual Machine type **MUST**
include '{vm-type}' as part of the parameter name with two
exceptions:
1.) The Resource OS::Nova::Server property availability_zone parameter
**MUST NOT** be prefixed with a common '{vm-type} identifier,
2.) The Resource OS::Nova::Server eight mandatory and optional metadata
parameters (vnf_name, vnf_id, vf_module_id, vf_module_name, vm_role,
vf_module_index, environment_context, workload_context) **MUST NOT**
be prefixed with a common '{vm-type}' identifier.
R-66729 A VNF’s Heat Orchestration Template’s Resource that is
associated with a unique Virtual Machine type **MUST** include
‘{vm-type}’ as part of the resource ID.
R-98407 A VNF's Heat Orchestration Template's '{vm-type}' **MUST** contain
only alphanumeric characters and/or underscores '_' and
**MUST NOT** contain any of the following strings: '_int' or 'int\_'
or '\_int\_'.
R-48067 A VNF's Heat Orchestration Template's {vm-type} **MUST NOT** be a
substring of {network-role}.
It may cause the Pre-Amsterdam VNF Validation Program (i.e.,
ICE Project) process to produce erroneous error messages.
R-32394 A VNF’s Heat Orchestration Template’s use of ‘{vm-type}’
in all Resource property parameter names **MUST** be the same case.
R-46839 A VNF’s Heat Orchestration Template’s use of
‘{vm-type}’ in all Resource IDs **MUST** be the same case.
R-36687 A VNF’s Heat Orchestration Template’s ‘{vm-type}’ case in
Resource property parameter names **SHOULD** match the case of
‘{vm-type}’ in Resource IDs and vice versa.
{network-role}
~~~~~~~~~~~~~~
The assignment of a {network-role} is discussed in `Networking`_.
R-21330 A VNF’s Heat Orchestration Template’s Resource property parameter
that is associated with external network **MUST** include the ‘{network-role}’’ as part of the parameter name
R-11168 A VNF's Heat Orchestration Template's Resource ID that is
associated with an external network **MUST** include the
'{network-role}' as part of the resource ID.
R-84322 A VNF's Heat Orchestration Template's Resource property
parameter that is associated with an internal network
**MUST** include 'int\_{network-role}' as part of the parameter
name, where 'int\_' is a hard coded string.
R-96983 A VNF's Heat Orchestration Template's Resource ID that is
associated with an internal network **MUST** include
'int\_{network-role}' as part of the Resource ID, where
'int\_' is a hard coded string.
R-26506 A VNF's Heat Orchestration Template's '{network-role}'
**MUST** contain only alphanumeric characters and/or
underscores '_' and **MUST NOT** contain any of the following
strings: '_int' or 'int\_' or '\_int\_'.
R-00977 A VNF’s Heat Orchestration Template’s ‘{network-role}’
**MUST NOT** be a substring of ‘{vm-type}’.
For example, if a VNF has a ‘{vm-type}’ of ‘oam’ and a
‘{network-role}’ of ‘oam_protected’ would be a violation of the requirement.
R-58424 A VNF’s Heat Orchestration Template’s use of ‘{network-role}’
in all Resource property parameter names **MUST** be the same case
R-21511 A VNF’s Heat Orchestration Template’s use of ‘{network-role}’
in all Resource IDs **MUST** be the same case.
R-86588 A VNF’s Heat Orchestration Template’s ‘{network-role}’ case
in Resource property parameter names **SHOULD** match the case
of ‘{network-role}’ in Resource IDs and vice versa.
Resource IDs
~~~~~~~~~~~~
Requirement R-75141 states a VNF’s Heat Orchestration Template’s
resource name (i.e., <resource ID>) MUST only contain alphanumeric
characters and underscores (‘_’).*
Requirement R-16447 states a VNF’s <resource ID> MUST be unique
across all Heat Orchestration Templates and all HEAT Orchestration
Template Nested YAML files that are used to create the VNF.
As stated previously, OpenStack requires the <resource ID> to be unique
to the Heat Orchestration Template and not unique across all Heat
Orchestration Templates the compose the VNF.
Heat Orchestration Template resources are described in `resources`_
R-54517 When a VNF’s Heat Orchestration Template’s resource is associated
with a single ‘{vm-type}’, the Resource ID **MUST** contain the ‘{vm-type}’.
R-96482 When a VNF’s Heat Orchestration Template’s resource is associated
with a single external network, the Resource ID MUST contain the text
‘{network-role}’.
R-98138 When a VNF’s Heat Orchestration Template’s resource is associated
with a single internal network, the Resource ID MUST contain the text
‘int\_{network-role}’.
R-82115 When a VNF's Heat Orchestration Template's resource is associated
with a single '{vm-type}' and a single external network, the Resource
ID text **MUST** contain both the '{vm-type}' and the '{network-role}'
- the '{vm-type}' **MUST** appear before the '{network-role}' and **MUST**
be separated by an underscore '_'
- e.g., '{vm-type}_{network-role}', '{vm-type}_{index}_{network-role}'
- note that an '{index}' value **MAY** separate the '{vm-type}' and the
'{network-role}' and when this occurs underscores **MUST** separate the
three values.
R-82551 When a VNF's Heat Orchestration Template's resource is associated
with a single '{vm-type}' and a single internal network, the Resource ID
**MUST** contain both the '{vm-type}' and the 'int\_{network-role}' and
- the '{vm-type}' **MUST** appear before the 'int\_{network-role}' and
**MUST** be separated by an underscore '_'
- (e.g., '{vm-type}\_int\_{network-role}', '{vm-type}_{index}\_int\_{network-role}')
- note that an '{index}' value **MAY** separate the '{vm-type}' and the
'int\_{network-role}' and when this occurs underscores **MUST** separate
the three values.
R-67793 When a VNF’s Heat Orchestration Template’s resource is associated
with more than one ‘{vm-type}’ and/or more than one internal and/or
external network, the Resource ID **MUST NOT** contain the ‘{vm-type}’
and/or ‘{network-role}’/’int\_{network-role}’. It also should contain the
term ‘shared’ and/or contain text that identifies the VNF
R-27970 When a VNF’s Heat Orchestration Template’s resource is associated
with more than one ‘{vm-type}’ and/or more than one internal and/or
external network, the Resource ID **MAY** contain the term ‘shared’
and/or **MAY** contain text that identifies the VNF.
R-11690 When a VNF’s Heat Orchestration Template’s Resource ID contains
an {index} value (e.g. multiple VMs of same {vm-type}), the ‘{index}’
**MUST** start at zero and increment by one.
The table below provides example OpenStack Heat resource ID for
resources only associated with one {vm-type} and/or one network.
The Requirements column states if the Resource ID Format MUST be followed
or SHOULD be followed. Resource ID formats that are marked MUST must be
followed, no deviations are permitted. Resource ID formats that are marked
SHOULD should be followed. However, deviations are permissible to meet
the needs of the VNF’s Heat Orchestration Template.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The resource OS::Nova::Server manages the running virtual machine (VM)
instance within an OpenStack cloud. (See
https://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::Server.)
Four properties of this resource must follow the ONAP parameter naming
convention. The four properties are:
1. image
2. flavor
3. name
4. availability\_zone
Requirement R-01455 defines how the ‘{vm-type]’ is defined.

R-55306 If a VNF’s Heat Orchestration Template’s OS::Nova::Server
Resource metadata map value parameter ‘vf\_module\_index’ **MUST NOT** be
used in a VNF’s Volume Template; it is not supported.
The vf_module_index parameter indicates which instance of the module is being
deployed into the VNF.
This parameter may be used in cases where multiple instances of the same
incremental module may be instantiated for scaling purposes. The index
can be used in the Heat Orchestration Template for indexing into a
pseudo-constant array parameter when unique values are required for each
module instance, e.g., for fixed private IP addresses on VM types.
The vf_module_index will start at 0 for the first instance of a module
type. Subsequent instances of the same module type will receive the
lowest unused index. This means that indexes will be reused if a module
is deleted and re-added. As an example, if three copies of a module are
deployed with vf_module_index values of 0, 1, and 2 then subsequently
the second one is deleted (index 1), and then re-added, index 1 will be
reused.
*Example*
In this example, the {vm-type} has been defined as oam_vm to represent
an OAM VM. An incremental heat module is used to deploy the OAM VM. The
OAM VM attaches to an internal control network which has a
{network-role} of ctrl. A maximum of four OAM VMs can be deployed. The
environment file contains the four IP addresses that each successive OAM
VM will be assigned. The vf_module_index is used as the index to
determine the IP assignment.

type: string
description: Neutron UUID for the {network-role} network
int_{network-role}_net_name:
type: string
description: Neutron name for the {network-role} network
Property: fixed\_ips, Map Property: subnet\_id
++++++++++++++++++++++++++++++++++++++++++++++
The property fixed\_ips is used to assign IPs to a port. The Map
Property subnet\_id specifies the subnet the IP is assigned from.
The property fixed\_ips and Map Property subnet\_id must be used if a
Cloud (i.e., DHCP) IP address assignment is being requested and the
Cloud IP address assignment is targeted at a specific subnet when two or
more subnets exist.
The property fixed\_ips and Map Property subnet\_id should not be used
if all IP assignments are fixed, or if the Cloud IP address assignment
does not target a specific subnet or there is only one subnet.
Note that DHCP assignment of IP addresses is also referred to as cloud
assigned IP addresses.

Internal Networks
_________________
R-20106 The VNF Heat Orchestration Template **MUST** adhere to the following naming convention for
the property fixed\_ips and Map Property subnet\_id parameter,
when the parameter is referencing the subnet of an “internal” network:
- int\_{network-role}\_subnet\_id if the subnet is an IPv4 subnet
- int\_{network-role}\_v6\_subnet\_id if the subnet is an IPv6 subnet
The parameter must be declared as type: string
The assumption is that internal networks are created in the base module.
The Neutron subnet network ID will be passed as an output parameter
(e.g., ONAP Base Module Output Parameter) to the incremental modules. In
the incremental modules, it will be defined as input parameter.
*Example Parameter Definition*

parameters:
int_{network-role}_subnet_id:
type: string
description: Neutron subnet UUID for the {network-role} network
int_{network-role}_v6_subnet_id:
type: string
description: Neutron subnet UUID for the {network-role} network
Property: fixed\_ips, Map Property: ip\_address
+++++++++++++++++++++++++++++++++++++++++++++++
The property fixed\_ips is used to assign IPs to a port. The Map
Property ip\_address specifies the IP address to be assigned to the
port.
The property fixed\_ips and Map Property ip\_address must be used when
statically assigning one or more IP addresses to a port. This is also
referred to as ONAP SDN-C IP address assignment. ONAP’s SDN-C provides
the IP address assignment.
An IP address is assigned to a port on a VM (referenced by {vm-type})
that is connected to an external network (referenced by {network-role})
or internal network (referenced by int\_{network-role}).
R-41177 The VNF Heat Orchestration Template **MUST** include {vm-type} and {network-role}
in the parameter name, when a SDN-C IP assignment is made to a
port connected to an external network.
When a SDN-C IP assignment is made to a port connected to an internal
network, the parameter name must contain {vm-type} and
int\_{network-role}.
IP Address Assignments on External Networks
___________________________________________
When the property fixed\_ips and Map Property ip\_address is used to
assign IP addresses to an external network, the parameter name is
dependent on the parameter type (comma\_delimited\_list or string) and
IP address type (IPv4 or IPv6).
R-84898 The VNF Heat Orchestration Template **MUST** adhere to the following naming convention,
when the parameter for property fixed\_ips and Map Property ip\_address
is declared type: comma\_delimited\_list:
- {vm-type}\_{network-role}\_ips for IPv4 address
- {vm-type}\_{network-role}\_v6\_ips for IPv6 address
Each element in the IP list should be assigned to successive instances
of {vm-type} on {network-role}.
The parameter must not be enumerated in the Heat environment file.

R-34960 The VNF Heat Orchestration Template **MUST** adhere to the following
naming convention,
when the parameter for property fixed\_ips and Map Property ip\_address
is declared type: string:
- {vm-type}\_{network-role}\_ip\_{index} for an IPv4 address
- {vm-type}\_{network-role}\_v6\_ip\_{index} for an IPv6 address

IP Address Assignment on Internal Networks
__________________________________________
When the property fixed\_ips and Map Property ip\_address is used to
assign IP addresses to an internal network, the parameter name is
dependent on the parameter type (comma\_delimited\_list or string) and
IP address type (IPv4 or IPv6).
R-62584 The VNF Heat Orchestration Template **MUST** adhere to
the following naming convention,
when the parameter for property fixed\_ips and Map Property ip\_address
is declared type: comma\_delimited\_list:
- {vm-type}\_int\_{network-role}\_ips for IPv4 address
- {vm-type}\_int\_{network-role}\_v6\_ips for IPv6 address
Each element in the IP list should be assigned to successive instances
of {vm-type} on {network-role}.
The parameter must be enumerated in the Heat environment file. Since an
internal network is local to the VNF, IP addresses can be re-used at
every VNF instance.

Property: allowed\_address\_pairs, Map Property: ip\_address
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The property allowed\_address\_pairs in the resource OS::Neutron::Port
allows the user to specify a mac\_address and/or ip\_address that will
pass through a port regardless of subnet. This enables the use of
protocols such as VRRP, which floats an IP address between two instances
to enable fast data plane failover. The map property ip\_address
specifies the IP address.
The allowed\_address\_pairs is an optional property. It is not required.
An ONAP Heat Orchestration Template allows the assignment of one IPv4
address allowed\_address\_pairs and/or one IPv6 address to a {vm-type}
and {network-role}/int\_{network-role} combination.
An ONAP Heat Orchestration Template allows the assignment of one IPv6
address allowed\_address\_pairs and/or one IPv6 address to a {vm-type}
and {network-role}/int\_{network-role} combination.
Note that the management of these IP addresses (i.e. transferring
ownership between active and standby VMs) is the responsibility of the
application itself.
Note that these parameters are **not** intended to represent Neutron
“Floating IP” resources, for which OpenStack manages a pool of public IP
addresses that are mapped to specific VM ports. In that case, the
individual VMs are not even aware of the public IPs, and all assignment
of public IPs to VMs is via OpenStack commands. ONAP does not support
Neutron-style Floating IPs.

Internal Networks
_________________
R-16805 The VNF Heat Orchestration Template **MUST** adhere to the following naming convention
for the property allowed\_address\_pairs and Map Property ip\_address
parameter when the parameter is referencing an “internal” network.
- {vm-type}\_int\_{network-role}\_floating\_ip for an IPv4 address
- {vm-type}\_int\_{network-role}\_floating\_v6\_ip for an IPv6 address
The parameter must be declared as type: string
The parameter must be enumerated in the Heat environment file.
*Example Parameter Definition*
.. code-block:: yaml
parameters:
{vm-type}_int_{network-role}_floating_ip:
type: string
description: VIP for {vm-type} VMs on the int_{network-role} network
{vm-type}_int_{network-role}_floating_v6_ip:
type: string
description: VIP for {vm-type} VMs on the int_{network-role} network
Multiple allowed\_address\_pairs for a {vm-type} / {network-role} combination
__________________________________________________________________
The parameter {vm-type}\_{network-role}\_floating\_ip provides only one
allowed address pair IPv4 address per {vm-type} and {network-role} pair.
The parameter {vm-type}\_{network-role}\_floating\_v6\_ip provides only
one allowed address pair IPv6 address per {vm-type} and {network-role}
pair.
If there is a need for multiple allowed address pair IPs for a given
{vm-type} and {network-role} combination within a VNF, then the
parameter names defined for the property fixed\_ips and Map Property
ip\_address should be used with the allowed\_address\_pairs property.
The examples below illustrate this.
*Example: A VNF has four load balancers. Each pair has a unique VIP.*
In this example, there are two administrative VM pairs. Each pair has
one VIP. The {network-role} has been defined as oam to represent an oam
network and the {vm-type} has been defined as admin for an
administrative VM.
Pair 1: Resources admin\_0\_port\_0 and admin\_1\_port\_0 share a unique
VIP, [admin\_oam\_ips,2]
Pair 2: Resources admin\_2\_port\_0 and admin\_3\_port\_0 share a unique
VIP, [admin\_oam\_ips,5]

*Example: A VNF has two load balancers. The pair of load balancers share
two VIPs.*
In this example, there is one load balancer pairs. The pair has two
VIPs. The {network-role} has been defined as oam to represent an oam
network and the {vm-type} has been defined as lb for a load balancer VM.
.. code-block:: yaml

allowed_address_pairs: [{ "ip_address": {get_param: [lb_oam_ips,2]}, {get_param: [lb_oam_ips,3] }}]
As a general rule, provide the fixed IPs for the VMs indexed first in
the CDL and then the VIPs as shown in the examples above.
ONAP SDN-C Assignment of allowed\_address\_pair IP Addresses
__________________________________________________________________
The following items must be taken into consideration when designing Heat
Orchestration Templates that expect ONAP’s SDN-C to assign
allowed\_address\_pair IP addresses via automation.
The VMs must be of the same {vm-type}.
The VMs must be created in the same module (base or incremental).
Resource Property “name”
~~~~~~~~~~~~~~~~~~~~~~~~
The parameter naming convention of the property name for the resource
OS::Nova::Server has been defined in
`Resource: OS::Nova::Server – Metadata Parameters`_.
This section provides the requirements how the property name for non
OS::Nova::Server resources must be defined when the property is used.
Not all resources require the property name (e.g., it is optional) and
some resources do not support the property.
R-85734 The VNF Heat Orchestration Template **MUST** use the intrinsic function str\_replace
in conjunction with the ONAP supplied metadata parameter
vnf\_name to generate a unique value,
when the property name for a non OS::Nova::Server resources is defined
in a Heat Orchestration Template.
This prevents the enumeration of a
unique value for the property name in a per instance environment file.
Note that
- In most cases, only the use of the metadata value vnf\_name is
required to create a unique property name
- the Heat Orchestration Template pseudo parameter 'OS::stack\_name’
may also be used in the str\_replace construct to generate a unique
name when the vnf\_name does not provide uniqueness
*Example: Property* name *for resource* OS::Neutron::SecurityGroup
.. code-block:: yaml
resources:
DNS_SECURITY_GROUP:
type: OS::Neutron::SecurityGroup
properties:

Contrail Issue with Values for the Property Name
++++++++++++++++++++++++++++++++++++++++++++++++
The Contrail GUI has a limitation displaying special characters. The
issue is documented in
https://bugs.launchpad.net/juniperopenstack/+bug/1590710. It is
recommended that special characters be avoided. However, if special
characters must be used, note that for the following resources:
- Virtual Machine
- Virtual Network
- Port
- Security Group
- Policies
- IPAM Creation
the only special characters supported are:
- “ ! $ ‘ ( ) = ~ ^ \| @ \` { } [ ] > , . \_
ONAP Output Parameter Names
~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP defines three types of Output Parameters as detailed in
`Output Parameters`_.
ONAP Base Module Output Parameters:
+++++++++++++++++++++++++++++++++++
ONAP Base Module Output Parameters do not have an explicit naming
convention. The parameter name must contain {vm-type} and {network-role}
when appropriate.
ONAP Volume Template Output Parameters:
+++++++++++++++++++++++++++++++++++++++
ONAP Base Module Output Parameters do not have an explicit naming
convention. The parameter name must contain {vm-type} when appropriate.
Predefined Output Parameters
++++++++++++++++++++++++++++
ONAP currently defines one predefined output parameter the OAM
Management IP Addresses.
OAM Management IP Addresses
___________________________
A VNF may have a management interface for application controllers to
interact with and configure the VNF. Typically, this will be via a
specific VM that performs a VNF administration function. The IP address
of this interface must be captured and inventoried by ONAP. The IP
address might be a VIP if the VNF contains an HA pair of management VMs,
or may be a single IP address assigned to one VM.
The Heat template may define either (or both) of the following Output
parameters to identify the management IP address.
- oam\_management\_v4\_address
- oam\_management\_v6\_address
*Notes*:
- The use of this output parameters are optional.
- The Management IP Address should be defined only once per VNF, so it
must only appear in one Module template
- If a fixed IP for the admin VM is passed as an input parameter, it
may be echoed in the output parameters. In this case, a IPv4 and/or
IPv6 parameter must be defined in the parameter section of the YAML
Heat template. The parameter maybe named oam\_management\_v4\_address
and/or oam\_management\_v6\_address or may be named differently.
- If the IP for the admin VM is obtained via DHCP, it may be obtained
from the resource attributes. In this case,
oam\_management\_v4\_address and/or oam\_management\_v6\_address must
not be defined in the parameter section of the YAML Heat template.
*Example: SDN-C Assigned IP Address echoed as*

Contrail Resource Parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP requires the parameter names of certain Contrail Resources to
follow specific naming conventions. This section provides these
requirements.
Contrail Network Parameters
+++++++++++++++++++++++++++
Contrail based resources may require references to a Contrail network
using the network FQDN.
External Networks
_________________
When the parameter associated with the Contrail Network is referencing
an “external” network, the parameter must adhere to the following naming
convention in the Heat Orchestration Template
- {network-role}\_net\_fqdn
The parameter must be declared as type: string
The parameter must not be enumerated in the Heat environment file.
*Example: Parameter declaration*
.. code-block:: yaml

*Example: Contrail Resource OS::ContrailV2::VirtualMachineInterface
Reference to a Network FQDN.*
In this example, the {network-role} has been defined as oam to represent
an oam network and the {vm-type} has been defined as fw for firewall.
The Contrail resource OS::ContrailV2::VirtualMachineInterface property
virtual\_network\_refs references a contrail network FQDN.

The parameter associated with the resource
OS::ContrailV2::InterfaceRouteTable property
interface\_route\_table\_routes, map property
interface\_route\_table\_routes\_route\_prefix is an ONAP Orchestration
Parameter.
The parameters must be named {vm-type}\_{network-role}\_route\_prefixes
in the Heat Orchestration Template.
The parameter must be declared as type: json
The parameter supports IP addresses in the format:
1. Host IP Address (e.g., 10.10.10.10)
2. CIDR Notation format (e.g., 10.0.0.0/28)
The parameter must not be enumerated in the Heat environment file.

Parameter Names in Contrail Resources
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Contrail Heat resource properties will use, when appropriate, the same
naming convention as OpenStack Heat resources. For example, the resource
OS::ContrailV2::InstanceIp has two properties that the parameter naming
convention is identical to properties in OS::Neutron::Port.
*Example: Contrail Resource OS::ContrailV2::InstanceIp, Property
instance\_ip\_address*
The property instance\_ip\_address uses the same parameter naming
convention as the property fixed\_ips and Map Property ip\_address in
OS::Neutron::Port. The resource is assigning an ONAP SDN-C Assigned IP
Address. The {network-role} has been defined as oam\_protected to
represent an oam protected network and the {vm-type} has been defined as
fw for firewall.
.. code-block:: yaml
CMD_FW_OAM_PROTECTED_RII:
type: OS::ContrailV2::InstanceIp
depends_on:
- FW_OAM_PROTECTED_RVMI
properties:
virtual_machine_interface_refs:
- get_resource: FW_OAM_PROTECTED_RVMI
virtual_network_refs:
- get_param: oam_protected_net_fqdn
instance_ip_address: { get_param: [fw_oam_protected_ips, get_param: index ] }
*Example: Contrail Resource OS::ContrailV2::InstanceIp, Property
subnet\_uuid*
The property instance\_ip\_address uses the same parameter naming
convention as the property fixed\_ips and Map Property subnet\_id in
OS::Neutron::Port. The resource is assigning a Cloud Assigned IP
Address. The {network-role} has been defined as “oam\_protected” to
represent an oam protected network and the {vm-type} has been defined as
“fw” for firewall.
.. code-block:: yaml
CMD_FW_SGI_PROTECTED_RII:
type: OS::ContrailV2::InstanceIp
depends_on:
- FW_OAM_PROTECTED_RVMI
properties:
virtual_machine_interface_refs:
- get_resource: FW_OAM_PROTECTED_RVMI
virtual_network_refs:
- get_param: oam_protected_net_fqdn
subnet_uuid: { get_param: oam_protected_subnet_id }
Cinder Volume Templates
^^^^^^^^^^^^^^^^^^^^^^^^
ONAP supports the independent deployment of a Cinder volume via separate
Heat Orchestration Templates, the Cinder Volume module. This allows the
volume to persist after VNF deletion so that they can be reused on
another instance (e.g., during a failover activity).
A Base Module or Incremental Module may have a corresponding volume
module. Use of separate volume modules is optional. A Cinder volume may
be embedded within the Base Module or Incremental Module if persistence
is not required.
R-47788 The VNF Heat Orchestration Template **MUST** have a 1:1 scope of a cinder volume module,
when it exists, with the Base Module or Incremental Module
A single volume module must create only the volumes
required by a single Incremental module or Base module.
The following rules apply to independent volume Heat templates:
- Cinder volumes must be created in a separate Heat Orchestration
Template from the Base Module or Incremental Module.
- A single Cinder volume module must include all Cinder volumes
needed by the Base/Incremental module.
- R-79531 The VNF Heat Orchestration Template **MUST** define “outputs” in the volume
template for each Cinder volume resource universally unique
identifier (UUID) (i.e. ONAP Volume Template Output Parameters).
- The VNF Incremental Module or Base Module must define input
parameters that match each Volume output parameter (i.e., ONAP Volume
Template Output Parameters).
- ONAP will supply the volume template outputs automatically to the
bases/incremental template input parameters.
- Volume modules may utilize nested Heat templates.
*Examples: Volume Template*
A VNF has a Cinder volume module, named incremental\_volume.yaml, that
creates an independent Cinder volume for a VM in the module
incremental.yaml. The incremental\_volume.yaml defines a parameter in
the output section, lb\_volume\_id\_0 which is the UUID of the cinder
volume. lb\_volume\_id\_0 is defined as a parameter in incremental.yaml.
ONAP captures the UUID value of lb\_volume\_id\_0 from the volume module
output statement and provides the value to the incremental module.
Note that the example below is not a complete Heat Orchestration
Template. The {vm-type} has been defined as “lb” for load balancer
incremental\_volume.yaml

properties:
instance_uuid: { get_resource: lb_0 }
volume_id: { get_param: lb_volume_id_0 }
ONAP Support of Environment Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The use of an environment file in OpenStack is optional. In ONAP, it is
mandatory.
R-86285 The VNF Heat Orchestration Template **MUST** have a
corresponding environment file, even if no parameters are required to be
enumerated.
(Note that ONAP, the open source version of ONAP, does not
programmatically enforce the use of an environment file.)
R-67205 The VNF Heat Orchestration Template **MUST** have a corresponding
environment file for a Base Module.
R-35727 The VNF Heat Orchestration Template **MUST** have a
corresponding environment file for an Incremental module.
R-22656 The VNF Heat Orchestration Template **MUST** have a corresponding environment file
for a Cinder Volume Module.
A nested heat template must not have an environment file; OpenStack does
not support it.
The environment file must contain parameter values for the ONAP
Orchestration Constants and VNF Orchestration Constants. These
parameters are identical across all instances of a VNF type, and
expected to change infrequently. The ONAP Orchestration Constants are
associated with OS::Nova::Server image and flavor properties (See
`Property: image`_ and `Property: flavor`_). Examples of VNF
Orchestration Constants are the networking parameters associated
with an internal network (e.g., private IP ranges) and Cinder
volume sizes.
The environment file must not contain parameter values for parameters
that are instance specific (ONAP Orchestration Parameters, VNF
Orchestration Parameters). These parameters are supplied to the Heat by
ONAP at orchestration time.
SDC Treatment of Environment Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter values enumerated in the environment file are used by SDC as
the default value. However, the SDC user may use the SDC GUI to
overwrite the default values in the environment file.
SDC generates a new environment file for distribution to MSO based on
the uploaded environment file and the user provided GUI updates. The
user uploaded environment file is discarded when the new file is
created. Note that if the user did not change any values via GUI
updates, the SDC generated environment file will contain the same values
as the uploaded file.
Use of Environment Files when using OpenStack “heat stack-create” CLI
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When ONAP is instantiating the Heat Orchestration Template, certain
parameter must not be enumerated in the environment file. This document
provides the details of what parameters should not be enumerated.
If the Heat Orchestration Template is to be instantiated from the
OpenStack Command Line Interface (CLI) using the command “heat
stack-create”, all parameters must be enumerated in the environment
file.
Heat Template Constructs
^^^^^^^^^^^^^^^^^^^^^^^^^
Nested Heat Templates
~~~~~~~~~~~~~~~~~~~~~
ONAP supports nested Heat templates per the OpenStack specifications.
Nested templates may be suitable for larger VNFs that contain many
repeated instances of the same VM type(s). A common usage pattern is to
create a nested template for each {vm-type} along with its supporting
resources. The VNF module may then reference these component templates
either statically by repeated definition or dynamically by using the
resource OS::Heat::ResourceGroup.
Nested Heat Template Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP supports nested Heat Orchestration Templates. A Base Module,
Incremental Module, and Cinder Volume Module may use nested heat.
A Heat Orchestration Template may reference the nested heat statically
by repeated definition.
A Heat Orchestration Template may reference the nested heat dynamically
using the resource OS::Heat::ResourceGroup.
A Heat Orchestration template must have no more than three levels of
nesting. ONAP supports a maximum of three levels.
Nested heat templates must be referenced by file name. The use of
resource\_registry in the environment file is not supported and must not
be used.
R-89868 The VNF Heat Orchestration Template **MUST** have unique file names within the scope
of the VNF for a nested heat yaml file.
R-52530 The VNF Heat Orchestration Template **MUST NOT** use a directory hierarchy for
nested templates. All templates must be in a single, flat directory
(per VNF).
A nested heat template may be used by any module within a given VNF.
Note that:
- Constrains must not be defined for any parameter enumerated in a
nested heat template.
- R-11041 The VNF Heat Orchestration Template **MUST** have the resource calling the
nested yaml file pass in as properties all parameters defined
in nested yaml file.
- R-61183 The VNF Heat Orchestration Template **MUST NOT** change the parameter names, when OS::Nova::Server metadata parameters are past into a nested heat
template.
- With nested templates, outputs are required to expose any resource
properties of the child templates to the parent template. Those would
not explicitly be declared as parameters but simply referenced as
get\_attribute targets against the “parent” resource.

Use of Heat ResourceGroup
+++++++++++++++++++++++++
The OS::Heat::ResourceGroup is a useful Heat element for creating
multiple instances of a given resource or collection of resources.
Typically, it is used with a nested Heat template, to create, for
example, a set of identical OS::Nova::Server resources plus their
related OS::Neutron::Port resources via a single resource in a master
template.
ResourceGroup may be used in ONAP to simplify the structure of a Heat
template that creates multiple instances of the same VM type.
However, there are important caveats to be aware of:
ResourceGroup does not deal with structured parameters
(comma-delimited-list and json) as one might typically expect. In
particular, when using a list-based parameter, where each list element
corresponds to one instance of the ResourceGroup, it is not possible to
use the intrinsic “loop variable” %index% in the ResourceGroup
definition.
For instance, the following is **not** valid Heat for ResourceGroup:
.. code-block:: yaml
type: OS::Heat::ResourceGroup
resource_def:
type: my_nested_vm_template.yaml
properties:
name: {get_param: [vm_name_list, %index%]}
Although this appears to use the nth entry of the vm\_name\_list list
for the nth element of the ResourceGroup, it will in fact result in a
Heat exception. When parameters are provided as a list (one for each
element of a ResourceGroup), you must pass the complete parameter to the
nested template along with the current index as separate parameters.
Below is an example of an **acceptable** Heat Syntax for a
ResourceGroup:
.. code-block:: yaml
type: OS::Heat::ResourceGroup
resource_def:
type: my_nested_vm_template.yaml
properties:
names: {get_param: vm_name_list}
index: %index%
You can then reference within the nested template as:
{ get\_param: [names, {get\_param: index} ] }
ResourceGroup Property count
____________________________
ONAP requires that the OS::Heat::ResourceGroup property count be defined
(even if the value is one) and that the value must be enumerated in the
environment file. This is required for ONAP to build the TOSCA model for
the VNF.
.. code-block:: yaml
type: OS::Heat::ResourceGroup
properties:
count: { get_param: count }
index_var: index
resource_def:
type: my_nested_vm_template.yaml
properties:
names: {get_param: vm_name_list}
index: index
Availability Zone and ResourceGroups
____________________________________
The resource OS::Heat::ResourceGroup and the property availability\_zone
has been an “issue” with a few VNFs since ONAP only supports
availability\_zone as a string parameter and not a
comma\_delimited\_list. This makes it difficult to use a ResourceGroup
to create Virtual Machines in more than one availability zone.
There are numerous solutions to this issue. Below are two suggested
usage patterns.
**Option 1:** create a CDL in the OS::Heat::ResourceGroup. In the
resource type: OS::Heat::ResourceGroup, create a comma\_delimited\_list
availability\_zones by using the intrinsic function list\_join.
.. code-block:: yaml
<resource name>:
type: OS::Heat::ResourceGroup
properties:
count: { get_param: node_count }
index_var: index
resource_def:
type: nested.yaml
properties:
index: index
avaialability_zones: { list_join: [',', [ { get_param: availability_zone_0 }, { get_param: availability_zone_1 } ] ] }
In the nested heat
.. code-block:: yaml
parameters:
avaialability_zones:
type: comma_delimited_list
description:
resources:
servers:
type: OS::Nova::Server
properties:
name: { get_param: [ dns_names, get_param: index ] }
image: { get_param: dns_image_name }
flavor: { get_param: dns_flavor_name }
availability_zone: { get_param: [ avaialability_zones, get_param: index ] }
**Option 2:** Create a resource group per availability zone. A separate
OS::Heat::ResourceGroup is created for each availability zone.
External References
~~~~~~~~~~~~~~~~~~~
Heat templates *should not* reference any HTTP-based resource
definitions, any HTTP-based nested configurations, or any HTTP-based
environment files.
- During orchestration, ONAP *should not* retrieve any such resources
from external/untrusted/unknown sources.
- VNF images should not contain such references in user-data or other
configuration/operational scripts that are specified via Heat or
encoded into the VNF image itself.
*Note:* HTTP-based references are acceptable if the HTTP-based reference
is accessing information with the VM private/internal network.
Heat Files Support (get\_file)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Heat Templates may contain the inclusion of text files into Heat
templates via the Heat get\_file directive. This may be used, for
example, to define a common “user-data” script, or to inject files into
a VM on startup via the “personality” property.
Support for Heat Files is subject to the following limitations:
R-76718 The VNF Heat Orchestration Template **MUST** reference the get\_files targets in
Heat templates by file name, and the corresponding files should be
delivered to ONAP along with the Heat templates.
R-41888 The VNE Heat **MUST NOT** use URL-based file retrieval.
R-62177 The VNF Heat Orchestration Template **MUST** have unique file names for the included
files within the scope of the VNF.
R-87848 The VNF Heat Orchestration Template **MUST** have all included files in a single, flat
directory per VNF. ONAP does not support a directory hierarchy.
- Included files may be used by all Modules within a given VNF.
- get\_file directives may be used in both non-nested and nested
templates
Key Pairs
~~~~~~~~~
When Nova Servers are created via Heat templates, they may be passed a
“keypair” which provides an ssh key to the ‘root’ login on the newly
created VM. This is often done so that an initial root key/password does
not need to be hard-coded into the image.
Key pairs are unusual in OpenStack, because they are the one resource
that is owned by an OpenStack User as opposed to being owned by an
OpenStack Tenant. As a result, they are usable only by the User that
created the keypair. This causes a problem when a Heat template attempts
to reference a keypair by name, because it assumes that the keypair was
previously created by a specific ONAP user ID.
When a keypair is assigned to a server, the SSH public-key is
provisioned on the VMs at instantiation time. They keypair itself is not
referenced further by the VM (i.e. if the keypair is updated with a new
public key, it would only apply to subsequent VMs created with that
keypair).
Due to this behavior, the recommended usage of keypairs is in a more
generic manner which does not require the pre-requisite creation of a
keypair. The Heat should be structured in such a way as to:
- Pass a public key as a parameter value instead of a keypair name
- Create a new keypair within The VNF Heat Orchestration Template (in the base
module) for use within that VNF
By following this approach, the end result is the same as pre-creating
the keypair using the public key – i.e., that public key will be
provisioned in the new VM. However, this recommended approach also makes
sure that a known public key is supplied (instead of having OpenStack
generate a public/private pair to be saved and tracked outside of ONAP).
It also removes any access/ownership issues over the created keypair.
The public keys may be enumerated as a VNF Orchestration Constant in the
environment file (since it is public, it is not a secret key), or passed
at run-time as instance-specific parameters. ONAP will never
automatically assign a public/private key pair.
*Example (create keypair with an existing ssh public-key for {vm-type}
of lb (for load balancer)):*
.. code-block:: yaml
parameters:
vnf_name:
type: string
lb_ssh_public_key:
type: string
resources:
my_keypair:
type: OS::Nova::Keypair
properties:
name:
str_replace:
template: VNF_NAME_key_pair
params:
VNF_NAME: { get_param: vnf_name }
public_key: {get_param: lb_ssh_public_key}
save_private_key: false
Security Groups
~~~~~~~~~~~~~~~
OpenStack allows a tenant to create Security groups and define rules
within the security groups.
Security groups, with their rules, may either be created in the Heat
Orchestration Template or they can be pre-created in OpenStack and
referenced within the Heat template via parameter(s). There can be a
different approach for security groups assigned to ports on internal
(intra-VNF) networks or external networks (inter-VNF). Furthermore,
there can be a common security group across all VMs for a specific
network or it can vary by VM (i.e., {vm-type}) and network type (i.e.,
{network-role}).
Anti-Affinity and Affinity Rules
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Anti-affinity or affinity rules are supported using normal OpenStack
OS::Nova::ServerGroup resources. Separate ServerGroups are typically
created for each VM type to prevent them from residing on the same host,
but they can be applied to multiple VM types to extend the
affinity/anti-affinity across related VM types as well.
*Example:*
In this example, the {network-role} has been defined as oam to represent
an oam network and the {vm-type} have been defined as lb for load
balancer and db for database.
.. code-block:: yaml
resources:
db_server_group:
type: OS::Nova::ServerGroup
properties:
name:
str_replace:
params:
$vnf_name: {get_param: vnf_name}
template: $vnf_name-server_group1
policies:
- anti-affinity
lb_server_group:
type: OS::Nova::ServerGroup
properties:
name:
str_replace:
params:
$vnf_name: {get_param: vnf_name}
template: $vnf_name-server_group2
policies:
- affinity
db_0:
type: OS::Nova::Server
properties:
...
scheduler_hints:
group: {get_resource: db_server_group}
db_1:
type: OS::Nova::Server
properties:
...
scheduler_hints:
group: {get_resource: db_server_group}
lb_0:
type: OS::Nova::Server
properties:
...
scheduler_hints:
group: {get_resource: lb_server_group}
Resource Data Synchronization
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For cases where synchronization is required in the orchestration of Heat
resources, two approaches are recommended:
- Standard Heat depends\_on property for resources
- Assures that one resource completes before the dependent resource
is orchestrated.
- Definition of completeness to OpenStack may not be sufficient
(e.g., a VM is considered complete by OpenStack when it is ready
to be booted, not when the application is up and running).
- Use of Heat Notifications
- Create OS::Heat::WaitCondition and OS::Heat::WaitConditionHandle
resources.
- Pre-requisite resources issue *wc\_notify* commands in user\_data.
- Dependent resource define depends\_on in the
OS::Heat::WaitCondition resource.
*Example: “depends\_on” case*
In this example, the {network-role} has been defined as oam to represent
an oam network and the {vm-type} has been defined as oam to represent an
oam server.
.. code-block:: yaml
resources:
oam_server_01:
type: OS::Nova::Server
properties:
name: {get_param: [oam_ names, 0]}
image: {get_param: oam_image_name}
flavor: {get_param: oam_flavor_name}
availability_zone: {get_param: availability_zone_0}
networks:
- port: {get_resource: oam01_port_0}
- port: {get_resource: oam01_port_1}
user_data:
scheduler_hints: {group: {get_resource: oam_servergroup}}
user_data_format: RAW
oam_01_port_0:
type: OS::Neutron::Port
properties:
network: {get_resource: oam_net_name}
fixed_ips: [{"ip_address": {get_param: [oam_oam_net_ips, 1]}}]
security_groups: [{get_resource: oam_security_group}]
oam_01_port_1:
type: OS::Neutron::Port
properties:
network: {get_param: oam_net_name}
fixed_ips: [{"ip_address": {get_param: [oam_oam_net_ips, 2]}}]
security_groups: [{get_resource: oam_security_group}]
oam_01_vol_attachment:
type: OS::Cinder::VolumeAttachment
depends_on: oam_server_01
properties:
volume_id: {get_param: oam_vol_1}
mountpoint: /dev/vdb
instance_uuid: {get_resource: oam_server_01}
High Availability
^^^^^^^^^^^^^^^^^
VNF/VM parameters may include availability zone IDs for VNFs that
require high availability.
The Heat must comply with the following requirements to specific
availability zone IDs:
- The Heat template should spread Nova and Cinder resources across the
availability zones as desired
Post Orchestration & VNF Configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Heat templates should contain a minimum amount of post-orchestration
configuration data. For instance, *do not* embed complex user-data
scripts in the template with large numbers of configuration parameters
to the Heat template.
- VNFs may provide configuration APIs for use after VNF creation. Such
APIs will be invoked via application and/or SDN controllers.
*Note:* It is important to follow this convention to the extent possible
even in the short-term as of the long-term direction.
VNFM Driver Development Steps
-----------------------------------------------------------
Refer to the ONAP documentation for VNF Provider instructions on integrating
vendor-specific VNFM adaptors with VF-C. The VNF driver development steps are
highlighted below.
1. Use the VNF SDK tools to design the VNF with TOSCA models to output
the VNF TOSCA package. Using the VNF SDK tools, the VNF package can be
validated and tested.
2. The VNF Provider supplies a vendor-specific VNFM driver in ONAP, which
is a microservice providing a translation interface from VF-C to
the vendor-specific VNFM. The interface definitions of vendor-specific
VNFM adaptors are supplied by the VNF Providers themselves.
Creating Vendor-Specific VNFM Adaptor Microservices
------------------------------------------------------------------------------------------------
VNFs can be managed by vendor-specific VNFMs. To add a vendor-specific
VNFM to ONAP, a vendor-specific VNFM adaptor is added to ONAP implementing
the interface of the vendor-specific VNFM.
A vendor-specific VNFM adaptor is a microservice with a unique name and
an appointed port. When started up, the vendor-specific VNFM adaptor
microservice is automatically registered to the Microservices Bus (MSB).
The following RESTful example describes the scenario of registering a
vendor-specific VNFM adaptor to MSB:
.. code-block:: java
POST /api/microservices/v1/services
{
"serviceName": "catalog",
"version": "v1",
"url": "/api/catalog/v1",
"protocol": "REST",
"visualRange": "1",
"nodes": [
{
"ip": "10.74.56.36",
"port": "8988",
"ttl": 0
}
]
}
