2. Edit the /etc/magnum/magnum.conf file:

   • In the [api] section, configure the host:

     [api]
     ...
     host = controller

   • In the [certificates] section, select barbican (or x509keypair if you don't have barbican installed):

     • Use barbican to store certificates:

       [certificates]
       ...
       cert_manager_type = barbican

     Important

     Barbican is recommended for production environments.

     • To store x509 certificates in magnum's database:

       [certificates]
       ...
       cert_manager_type = x509keypair

   • In the [cinder_client] section, configure the region name:

     [cinder_client]
     ...
     region_name = RegionOne

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

     [database]
     ...
     connection = mysql+pymysql://magnum:MAGNUM_DBPASS@controller/magnum

     Replace MAGNUM_DBPASS with the password you chose for the magnum database.

   • In the [keystone_authtoken] and [trust] sections, configure Identity service access:

     [keystone_authtoken]
     ...
     memcached_servers = controller:11211
     auth_version = v3
     auth_uri = http://controller:5000/v3
     project_domain_id = default
     project_name = service
     user_domain_id = default
     password = MAGNUM_PASS
     username = magnum
     auth_url = http://controller:35357
     auth_type = password
     
     [trust]
     ...
     trustee_domain_name = magnum
     trustee_domain_admin_name = magnum_domain_admin
     trustee_domain_admin_password = DOMAIN_ADMIN_PASS

     Replace MAGNUM_PASS with the password you chose for the magnum user in the Identity service and DOMAIN_ADMIN_PASS with the password you chose for the magnum_domain_admin user.

   • In the [oslo_messaging_notifications] section, configure the driver:

     [oslo_messaging_notifications]
     ...
     driver = messaging

   • In the [DEFAULT] section, configure RabbitMQ message queue access:
