Petr Kovar 3a93b123ac Add install-guide for heat 
This adds heat-specific contents of the OpenStack Installation Guide
in the heat repo per [1]. A separate change will remove the heat
contents from the OpenStack Installation Guide for Newton per [2].

The heat install-guide structure is based on Install Guide
Cookiecutter [3].

Also adds tox.ini environment for install-guide and adds
openstackdocs-theme to test-requirements.txt.

Install and configure for Red Hat Enterprise Linux and CentOS

This section describes how to install and configure the Orchestration service for Red Hat Enterprise Linux 7 and CentOS 7.

Prerequisites

Before you install and configure Orchestration, you must create a database, service credentials, and API endpoints. Orchestration also requires additional information in the Identity service.

  1. To create the database, complete these steps:

    • Use the database access client to connect to the database server as the root user:

      $ mysql -u root -p

    • Create the heat database:

      CREATE DATABASE heat;

    • Grant proper access to the heat database:

      GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'localhost' \
  IDENTIFIED BY 'HEAT_DBPASS';
GRANT ALL PRIVILEGES ON heat.* TO 'heat'@'%' \
  IDENTIFIED BY 'HEAT_DBPASS';

      Replace HEAT_DBPASS with a suitable password.

    • Exit the database access client.

  2. Source the admin credentials to gain access to admin-only CLI commands:

    $ . admin-openrc

  3. To create the service credentials, complete these steps:

    • Create the heat user:

      $ openstack user create --domain default --password-prompt heat
User Password:
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | ca2e175b851943349be29a328cc5e360 |
| name      | heat                             |
+-----------+----------------------------------+

    • Add the admin role to the heat user:

      $ openstack role add --project service --user heat admin

      Note

      This command provides no output.

    • Create the heat and heat-cfn service entities:

      $ openstack service create --name heat \
  --description "Orchestration" orchestration
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Orchestration                    |
| enabled     | True                             |
| id          | 727841c6f5df4773baa4e8a5ae7d72eb |
| name        | heat                             |
| type        | orchestration                    |
+-------------+----------------------------------+

$ openstack service create --name heat-cfn \
  --description "Orchestration"  cloudformation
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Orchestration                    |
| enabled     | True                             |
| id          | c42cede91a4e47c3b10c8aedc8d890c6 |
| name        | heat-cfn                         |
| type        | cloudformation                   |
+-------------+----------------------------------+

  4. Create the Orchestration service API endpoints:

    $ openstack endpoint create --region RegionOne \
  orchestration public http://controller:8004/v1/%\(tenant_id\)s
+--------------+-----------------------------------------+
| Field        | Value                                   |
+--------------+-----------------------------------------+

| region       | RegionOne                               |
| region_id    | RegionOne                               |
| service_id   | 727841c6f5df4773baa4e8a5ae7d72eb        |
| service_name | heat                                    |
| service_type | orchestration                           |
| url          | http://controller:8004/v1/%(tenant_id)s |
+--------------+-----------------------------------------+

+--------------+-----------------------------------------+
| Field        | Value                                   |
+--------------+-----------------------------------------+

  5. Orchestration requires additional information in the Identity service to manage stacks. To add this information, complete these steps:

    • Create the heat domain that contains projects and users for stacks:

      $ openstack domain create --description "Stack projects and users" heat
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Stack projects and users         |
| enabled     | True                             |
| id          | 0f4d1bd326f2454dacc72157ba328a47 |
| name        | heat                             |
+-------------+----------------------------------+

    • Create the heat_domain_admin user to manage projects and users in the heat domain:

      $ openstack user create --domain heat --password-prompt heat_domain_admin
User Password:
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | 0f4d1bd326f2454dacc72157ba328a47 |
| enabled   | True                             |
| id        | b7bd1abfbcf64478b47a0f13cd4d970a |
| name      | heat_domain_admin                |
+-----------+----------------------------------+

    • Add the admin role to the heat_domain_admin user in the heat domain to enable administrative stack management privileges by the heat_domain_admin user:

      $ openstack role add --domain heat --user-domain heat --user heat_domain_admin admin

      Note

      This command provides no output.

    • Create the heat_stack_owner role:

      $ openstack role create heat_stack_owner
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | None                             |
| id        | 15e34f0c4fed4e68b3246275883c8630 |
| name      | heat_stack_owner                 |
+-----------+----------------------------------+

    • Add the heat_stack_owner role to the demo project and user to enable stack management by the demo user:

      $ openstack role add --project demo --user demo heat_stack_owner

      Note

      This command provides no output.

      Note

      You must add the heat_stack_owner role to each user that manages stacks.

    • Create the heat_stack_user role:

      $ openstack role create heat_stack_user
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | None                             |
| id        | 88849d41a55d4d1d91e4f11bffd8fc5c |
| name      | heat_stack_user                  |
+-----------+----------------------------------+

      Note

      The Orchestration service automatically assigns the heat_stack_user role to users that it creates during stack deployment. By default, this role restricts API <Application Programming Interface (API)> operations. To avoid conflicts, do not add this role to users with the heat_stack_owner role.

Install and configure components

Note

Default configuration files vary by distribution. You might need to add these sections and options rather than modifying existing sections and options. Also, an ellipsis (...) in the configuration snippets indicates potential default configuration options that you should retain.

  1. Install the packages:

    # yum install openstack-heat-api openstack-heat-api-cfn \
  openstack-heat-engine

  2. Edit the /etc/heat/heat.conf file and complete the following actions:

    • In the [database] section, configure database access:

      [database]
...
connection = mysql+pymysql://heat:HEAT_DBPASS@controller/heat

      Replace HEAT_DBPASS with the password you chose for the Orchestration database.

    • In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

      [DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

    • In the [keystone_authtoken], [trustee], [clients_keystone], and [ec2authtoken] sections, configure Identity service access:

      [keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = heat
password = HEAT_PASS

[trustee]
...
auth_plugin = password
auth_url = http://controller:35357
username = heat
password = HEAT_PASS
user_domain_name = default

[clients_keystone]
...
auth_uri = http://controller:35357

[ec2authtoken]
...
auth_uri = http://controller:5000

      Replace HEAT_PASS with the password you chose for the heat user in the Identity service.

    • In the [DEFAULT] section, configure the metadata and wait condition URLs:

      [DEFAULT]
...
heat_metadata_server_url = http://controller:8000
heat_waitcondition_server_url = http://controller:8000/v1/waitcondition

    • In the [DEFAULT] section, configure the stack domain and administrative credentials:

      [DEFAULT]
...
stack_domain_admin = heat_domain_admin
stack_domain_admin_password = HEAT_DOMAIN_PASS
stack_user_domain_name = heat

      Replace HEAT_DOMAIN_PASS with the password you chose for the heat_domain_admin user in the Identity service.

  3. Populate the Orchestration database:

    # su -s /bin/sh -c "heat-manage db_sync" heat

    Note

    Ignore any deprecation messages in this output.

Finalize installation

  • Start the Orchestration services and configure them to start when the system boots:

    # systemctl enable openstack-heat-api.service \
  openstack-heat-api-cfn.service openstack-heat-engine.service
# systemctl start openstack-heat-api.service \
  openstack-heat-api-cfn.service openstack-heat-engine.service
