Resource Assignment
===================
.. toctree::
:maxdepth: 1
Component executor:
===================
Workflow:
=========
A workflow defines an overall action to be taken for the service; it can be composed of a set of sub-actions to execute. Currently, workflows are backed by Directed Graph engine.
A CBA can have as many workflow as needed.
Template:
=========
A template is an artifact.
A template is parameterized and each parameter must be defined in a corresponding mapping file.
In order to know which mapping correlate to which template, the file name must start with an artifact-prefix, serving as identifier to the overall template + mapping.
The requirement is as follow:
${artifact-prefix}-template
${artifact-prefix}-mapping
A template can represent anything, such as device config, payload to interact with 3rd party systems, resource-accumulator template, etc...
Mapping:
========
Defines the contract of each resource to be resolved. Each placeholder in the template must have a corresponding mapping definition.
A mapping is comprised of:
- name
- required / optional
- type (support complex type)
- dictionary-name
- dictionary-source
Dependencies:
=============
This allows to make sure given resources get resolved prior the resolution of the resources defining the dependency.
The dictionary fields reference to a specific data dictionary.
Resource accumulator:
=====================
In order to resolve HEAT environment variables, resource accumulator templates are being in used for Dublin.
These templates are specific to the pre-instantiation scenario, and relies on GR-API within SDNC.
It is composed of the following sections:
resource-accumulator-resolved-data: defines all the resources that can be resolved directly from the context. It expresses a direct mapping between the name of the resource and its value.
capability-data: defines what capability to use to create a specific resource, along with the ingredients required to invoke the capability and the output mapping.
- Scripts
- Library
- NetconfClient
In order to facilitate NETCONF interaction within scripts, a python NetconfClient binded to our Kotlin implementation is made available. This NetconfClient can be used when using the netconf-component-executor.
The client can be find here: https://github.com/onap/ccsdk-apps/blob/master/components/scripts/python/ccsdk_netconf/netconfclient.py
