      NOTE: updating this setting to a source that is known to provide
      a later version of OpenStack will trigger a software upgrade unless
      action-managed-upgrade is set to True.
  action-managed-upgrade:
    type: boolean
    default: False
    description: |
      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.

  use-internal-endpoints:
    type: boolean
    default: False

      Openstack mostly defaults to using public endpoints for
      internal communication between services. If set to True this option will
      configure services to use internal endpoints where possible.
  ceph-osd-replication-count:
    type: int
    default: 3
    description: |
      This value dictates the number of replicas ceph must make of any
      object it stores within the images rbd pool. Of course, this only
      applies if using Ceph as a backend store. Note that once the images
      rbd pool has been created, changing this value will not have any
      effect (although it can be changed in ceph by manually configuring
      your ceph cluster).
  ceph-pool-weight:
    type: int
    default: 5
    description: |
      Defines a relative weighting of the pool as a percentage of the total
      amount of data in the Ceph cluster. This effectively weights the number
      of placement groups for the pool created to be appropriately portioned
      to the amount of data expected. For example, if the compute images
      for the OpenStack compute instances are expected to take up 20% of the
      overall configuration then this value would be specified as 20. Note -
      it is important to choose an appropriate value for the pool weight as
      this directly affects the number of placement groups which will be
      created for the pool. The number of placement groups for a pool can
      only be increased, never decreased - so it is important to identify the
      percent of data that will likely reside in the pool.
  restrict-ceph-pools:
    type: boolean

      Optionally restrict Ceph key permissions to access pools as required.

  ec-rbd-metadata-pool:
    type: string
    default:
    description: |
      Name of the metadata pool to be created (for RBD use-cases). If not
      defined a metadata pool name will be generated based on the name of

    default:
    description: |
      (lrc plugin - l) Group the coding and data chunks into sets of size l.
      For instance, for k=4 and m=2, when l=3 two groups of three are created.
      Each set can be recovered without reading chunks from another set. Note
      that using the lrc plugin does incur more raw storage usage than isa or
      jerasure in order to reduce the cost of recovery operations.
  ec-profile-crush-locality:
    type: string
    default:
    description: |
      (lrc plugin) The type of the crush bucket in which each set of chunks
      defined by l will be stored. For instance, if it is set to rack, each
      group of l chunks will be placed in a different rack. It is used to
      create a CRUSH rule step such as step choose rack. If it is not set,
      no such grouping is done.

    type: int
    default:
    description: |
      (shec plugin - c) The number of parity chunks each of which includes
      each data chunk in its calculation range. The number is used as a

      The CPU core multiplier to use when configuring worker processes for
      this service. By default, the number of workers for each daemon is
      set to twice the number of CPU cores a service unit has. This default
      value will be capped to 4 workers unless this configuration option
      is set.
  expose-image-locations:
    type: boolean
    default: True
    description: |
      Expose underlying image locations via the API. Enabling this is
      useful especially when using Ceph for image storage. Only disable
      this option if you do not wish to use copy-on-write clones of RAW
      format images with Ceph in Cinder and Nova.
      .
      NOTE: When S3 backend is enabled, this value will be ignored. The
      charm will not expose the image location for all backends not to
      expose S3 credentials.
  restrict-image-location-operations:
    type: boolean
    default: False
    description: |
      If this is set to True, all *_image_location operations in the Glance api
      will be restricted to role:admin which will result in non-admin users no
      longer being able to view the "locations" information for an image.
      This only affects environments that have expose-image-locations set to
      True.
      WARNING: enabling this restriction will cause Nova to no longer be able
      to create COW clones or snapshots for non-admin users when using the

      the write access isn’t available, a BadStoreConfiguration exception is
      raised and the filesystem store may not be available for adding new
