  1. Edit the /etc/magnum/magnum.conf file:
    • In the [api] section, configure the host:

      [api]
      ...
      host = CONTROLLER_IP

      Replace CONTROLLER_IP with the IP address on which you wish magnum api should listen.

    • 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
      www_authenticate_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:5000
      auth_type = password
      admin_user = magnum
      admin_password = MAGNUM_PASS
      admin_tenant_name = service
      
      [trust]
      ...
      trustee_domain_name = magnum
      trustee_domain_admin_name = magnum_domain_admin
      trustee_domain_admin_password = DOMAIN_ADMIN_PASS
      trustee_keystone_interface = KEYSTONE_INTERFACE

      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.

      Replace KEYSTONE_INTERFACE with either public or internal depending on your network configuration. If your instances cannot reach internal keystone endpoint which is often the case in production environments it should be set to public. Default to public

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

      [oslo_messaging_notifications]
      ...
      driver = messaging
    • In the [DEFAULT] section, configure RabbitMQ message queue access:

      [DEFAULT]
      ...
      transport_url = rabbit://openstack:RABBIT_PASS@controller

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