Install and configure

This section describes how to install and configure the Orchestration service, code-named heat, on the controller node.

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:

    $ source admin-openrc.sh

  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 | default                          |
| 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 |
+--------------+-----------------------------------------+

  orchestration internal http://controller:8004/v1/%\(tenant_id\)s
+--------------+-----------------------------------------+
| Field        | Value                                   |
+--------------+-----------------------------------------+
| enabled      | True                                    |
| id           | 9489f78e958e45cc85570fec7e836d98        |

  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 heat_domain_admin admin

      Note

      This command provides no output.

    • Create the heat_stack_owner role:

      $ openstack role create heat_stack_owner
+-------+----------------------------------+
| Field | Value                            |
+-------+----------------------------------+
| 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                            |
+-------+----------------------------------+
| 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 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 python-heatclient

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

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

      [database]
...
connection = mysql://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
auth_plugin = password
project_domain_id = default
user_domain_id = 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_id = default

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

[ec2authtoken]
...
auth_uri = http://controller:5000/v3

      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.

    • (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

      [DEFAULT]
...
verbose = True

  2. Populate the Orchestration database:

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

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
