+ONAP HEAT Template
+------------------
+
+Source files
+~~~~~~~~~~~~
+
+- Template file: https://git.onap.org/demo/plain/heat/ONAP/onap_openstack.yaml
+- Environment file: https://git.onap.org/demo/plain/heat/ONAP/onap_openstack.env
+
+Description
+~~~~~~~~~~~
+
+The ONAP HEAT template spins up the entire ONAP platform. The template,
+onap\_openstack.yaml, comes with an environment file,
+onap\_openstack.env, in which all the default values are defined.
+
+.. note::
+ onap\_openstack.yaml AND onap\_openstack.env ARE THE HEAT TEMPLATE
+ AND ENVIRONMENT FILE CURRENTLY SUPPORTED.
+ onap\_openstack\_float.yaml/env AND onap\_openstack\_nofloat.yaml/env
+ AREN'T UPDATED AND THEIR USAGE IS NOT SUGGESTED.
+
+The HEAT template is composed of two sections: (i) parameters, and (ii)
+resources.
+The parameter section contains the declaration and
+description of the parameters that will be used to spin up ONAP, such as
+public network identifier, URLs of code and artifacts repositories, etc.
+The default values of these parameters can be found in the environment
+file.
+
+The resource section contains the definition of:
+
+- ONAP Private Management Network, which ONAP components use to communicate with each other and with VNFs
+- ONAP Virtual Machines (VMs)
+- Public/private key pair used to access ONAP VMs
+- Virtual interfaces towards the ONAP Private Management Network
+- Disk volumes.
+
+Each VM specification includes Operating System image name, VM size
+(i.e. flavor), VM name, etc. Each VM has two virtual network interfaces:
+one towards the public network and one towards the ONAP Private
+Management network, as described above. Furthermore, each VM runs a
+post-instantiation script that downloads and installs software
+dependencies (e.g. Java JDK, gcc, make, Python, ...) and ONAP software
+packages and docker containers from remote repositories.
+
+When the HEAT template is executed, the Openstack HEAT engine creates
+the resources defined in the HEAT template, based on the parameters
+values defined in the environment file.
+
+Environment file
+~~~~~~~~~~~~~~~~
+
+Before running HEAT, it is necessary to customize the environment file.
+Indeed, some parameters, namely public\_net\_id, pub\_key,
+openstack\_tenant\_id, openstack\_username, and openstack\_api\_key,
+need to be set depending on the user's environment:
+
+**Global parameters**
+
+::
+
+ public_net_id: PUT YOUR NETWORK ID/NAME HERE
+ pub_key: PUT YOUR PUBLIC KEY HERE
+ openstack_tenant_id: PUT YOUR OPENSTACK PROJECT ID HERE
+ openstack_username: PUT YOUR OPENSTACK USERNAME HERE
+ openstack_api_key: PUT YOUR OPENSTACK PASSWORD HERE
+ horizon_url: PUT THE HORIZON URL HERE
+ keystone_url: PUT THE KEYSTONE URL HERE (do not include version number)
+
+openstack\_region parameter is set to RegionOne (OpenStack default). If
+your OpenStack is using another Region, please modify this parameter.
+
+public\_net\_id is the unique identifier (UUID) or name of the public
+network of the cloud provider. To get the public\_net\_id, use the
+following OpenStack CLI command (ext is the name of the external
+network, change it with the name of the external network of your
+installation)
+
+::
+
+ openstack network list | grep ext | awk '{print $2}'
+
+pub\_key is string value of the public key that will be installed in
+each ONAP VM. To create a public/private key pair in Linux, please
+execute the following instruction:
+
+::
+
+ user@ubuntu:~$ ssh-keygen -t rsa
+
+The following operations to create the public/private key pair occur:
+
+::
+
+ Generating public/private rsa key pair.
+ Enter file in which to save the key (/home/user/.ssh/id_rsa):
+ Created directory '/home/user/.ssh'.
+ Enter passphrase (empty for no passphrase):
+ Enter same passphrase again:
+ Your identification has been saved in /home/user/.ssh/id_rsa.
+ Your public key has been saved in /home/user/.ssh/id_rsa.pub.
+
+openstack\_username, openstack\_tenant\_id (password), and
+openstack\_api\_key are user's credentials to access the
+OpenStack-based cloud.
+
+**Images and flavors parameters**
+
+::
+
+ ubuntu\_1404\_image: PUT THE UBUNTU 14.04 IMAGE NAME HERE
+ ubuntu\_1604\_image: PUT THE UBUNTU 16.04 IMAGE NAME HERE
+ flavor\_small: PUT THE SMALL FLAVOR NAME HERE
+ flavor\_medium: PUT THE MEDIUM FLAVOR NAME HERE
+ flavor\_large: PUT THE LARGE FLAVOR NAME HERE
+ flavor\_xlarge: PUT THE XLARGE FLAVOR NAME HERE
+ flavor\_xxlarge: PUT THE XXLARGE FLAVOR NAME HERE
+
+To get the images in your OpenStack environment, use the following
+OpenStack CLI command:
+
+::
+
+ openstack image list | grep 'ubuntu'
+
+To get the flavor names used in your OpenStack environment, use the
+following OpenStack CLI command:
+
+::
+
+ openstack flavor list
+
+**DNS parameters**
+
+::
+
+ dns\_list: PUT THE ADDRESS OFTHE EXTERNAL DNS HERE (e.g. a comma-separated list of IP addresses in your /etc/resolv.conf in UNIX-based Operating Systems). THIS LIST MUST INCLUDE THE DNS SERVER THAT OFFERS DNS AS AS SERVICE (see DCAE section below for more details)
+ external\_dns: PUT THE FIRST ADDRESS OF THE EXTERNAL DNS LIST HERE oam\_network\_cidr: 10.0.0.0/16
+
+You can use the Google Public DNS 8.8.8.8 and 4.4.4.4 address or your internal DNS servers
+
+**DCAE Parameters**
+
+DCAE spins up ONAP's data collection and analytics system in two phases.
+The first is the launching of a bootstrap VM that is specified in the
+ONAP Heat template. This VM requires a number of deployment specific
+conifiguration parameters being provided so that it can subsequently
+bring up the DCAE system. There are two groups of parameters.
+
+The first group relates to the launching of DCAE VMs, including parameters such as
+the keystone URL and additional VM image IDs/names. DCAE VMs are
+connected to the same internal network as the rest of ONAP VMs, but
+dynamically spun up by the DCAE core platform. Hence these parameters
+need to be provided to DCAE. Note that although DCAE VMs will be
+launched in the same tenant as the rest of ONAP, because DCAE may use
+MultiCloud node as the agent for interfacing with the underying cloud,
+it needs a separate keystone URL (which points to MultiCloud node
+instead of the underlying cloud).
+
+The second group of configuration parameters relate to DNS As A Service support (DNSaaS).
+DCAE requires DNSaaS for registering its VMs into organization-wide DNS service. For
+OpenStack, DNSaaS is provided by Designate. Designate support can be
+provided via an integrated service endpoint listed under the service
+catalog of the OpenStack installation; or proxyed by the ONAP MultiCloud
+service. For the latter case, a number of parameters are needed to
+configure MultiCloud to use the correct Designate service. These
+parameters are described below:
+
+::
+
+ dcae_keystone_url: PUT THE KEYSTONE URL OF THE OPENSTACK INSTANCE WHERE DCAE IS DEPLOYED (Note: put the MultiCloud proxy URL if the DNSaaS is proxyed by MultiCloud)
+ dcae_centos_7_image: PUT THE CENTOS7 IMAGE ID/NAME AVAILABLE AT THE OPENSTACK INSTANCE WHERE DCAE IS DEPLOYED
+ dcae_security_group: PUT THE SECURITY GROUP ID/NAME TO BE USED AT THE OPENSTACK INSTANCE WHERE DCAE IS DEPLOYED
+ dcae_key_name: PUT THE ACCESS KEY-PAIR NAME REGISTER AT THE OPENSTACK INSTANCE WHERE DCAE IS DEPLOYED
+ dcae_public_key: PUT THE PUBLIC KEY OF A KEY-PAIR USED FOR DCAE BOOTSTRAP NODE TO COMMUNICATE WITH DCAE VMS
+ dcae_private_key: PUT THE PRIVATE KEY OF A KEY-PAIR USED FOR DCAE BOOTSTRAP NODE TO COMMUNICATE WITH DCAE VMS
+
+ dnsaas_config_enabled: true or false FOR WHETHER DNSAAS IS PROXYED
+ dnsaas_region: PUT THE REGION OF THE OPENSTACK INSTANCE WHERE DNSAAS IS PROVIDED
+ dnsaas_tenant_id: PUT THE TENANT ID/NAME OF THE OPENSTACK INSTANCE WHERE DNSAAS IS PROVIDED
+ dnsaas_keystone_url: PUT THE KEYSTONE URL OF THE OPENSTACK INSTANCE WHERE DNSAAS IS PROVIDED
+ dnsaas_username: PUT THE USERNAME OF THE OPENSTACK INSTANCE WHERE DNSAAS IS PROVIDED
+ dnsaas_password: PUT THE PASSWORD OF THE OPENSTACK INSTANCE WHERE DNSAAS IS PROVIDED
+
