Nova Cell Controller

Learn about configurations >

• action-managed-upgrade | boolean

  If True enables openstack upgrades for this charm via juju actions. You will still need to set openstack-origin to the new repository but instead of an upgrade running automatically across all units, it will wait for you to execute the openstack-upgrade action for this charm on each unit. If False it will revert to existing behavior of upgrading all units on config change.

  Comma-separated list of key=value config flags. These values will be placed in the nova.conf [DEFAULT] section.

  Enable debug logging.

• os-internal-hostname | string

  The hostname or address of the internal endpoints created in the keystone identity provider. . This value will be used for internal endpoints.
