Configuring ironic-api service

1. The Bare Metal service stores information in a database. This guide uses the MySQL database that is used by other OpenStack services.

   Configure the location of the database via the connection option. In the following, replace IRONIC_DBPASSWORD with the password of your ironic user, and replace DB_IP with the IP address where the DB server is located:

   [database]
   
   # The SQLAlchemy connection string used to connect to the
   # database (string value)
   connection=mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic?charset=utf8

2. Configure the ironic-api service to use the RabbitMQ message broker by setting the following option. Replace RPC_* with appropriate address details and credentials of RabbitMQ server:

   [DEFAULT]
   
   # A URL representing the messaging driver to use and its full
   # configuration. (string value)
   transport_url = rabbit://RPC_USER:RPC_PASSWORD@RPC_HOST:RPC_PORT/

3. Configure the ironic-api service to use these credentials with the Identity service. Replace PUBLIC_IDENTITY_IP with the public IP of the Identity server, PRIVATE_IDENTITY_IP with the private IP of the Identity server and replace IRONIC_PASSWORD with the password you chose for the ironic user in the Identity service:

   [DEFAULT]
   
   # Authentication strategy used by ironic-api: one of
   # "keystone" or "noauth". "noauth" should not be used in a
   # production environment because all authentication will be
   # disabled. (string value)
   auth_strategy=keystone
   
   [keystone_authtoken]
   
   # Authentication type to load (string value)
   auth_type=v3password
   
   # Complete public Identity API endpoint (string value)
   auth_uri=http://PUBLIC_IDENTITY_IP:5000/v3/
   
   # Complete admin Identity API endpoint. (string value)
   auth_url=http://PRIVATE_IDENTITY_IP:35357/v3/
   
   # Service username. (string value)
   admin_user=ironic
   
   # Service account password. (string value)
   admin_password=IRONIC_PASSWORD
   
   # Service tenant name. (string value)
   admin_tenant_name=service

4. Create the Bare Metal service database tables:

   $ ironic-dbsync --config-file /etc/ironic/ironic.conf create_schema

5. Restart the ironic-api service:

   Fedora/RHEL7/CentOS7:
     sudo systemctl restart openstack-ironic-api
   
   Ubuntu:
     sudo service ironic-api restart
