  use_swift:
    type: boolean
    default: True
    description: >
        Controls whether swift will be used for image metadata storage
        or not. If set to False, image metadata will not be written to
        object store while images will still be synced to Glance.

      description: |
          Controls whether Juju model proxy settings are going to be used
          by sstream-mirror-glance when connecting to object-store endpoints
          from the Keystone catalog.

    description: "This is prefixed to the object name when uploading to glance."
  visibility:

    description: >
      Visibility to apply to stored images. Possible values are
      'public', 'private', 'community', and 'shared'.      
  custom_properties:

    description: >
      Space separated list of custom properties (format key=value) to be

      hw_vif_multiqueue_enabled.      
  set_latest_property:

    default: false
    description: >
      Set property `latest=true` to recently synced image and then remove
      the `latest` property from all the os_version/architecture matching
      images.      
  content_id_template:
    type: string
    default: "auto.sync"
    description: >
      A Python-style .format() template to use when generating
      content_id properties for images uploaded to glance.

      The content_id is considered when matching images between the
      source and destination to decide which images to mirror.  By
      varying this value you can mirror disjoint sets of images from
      the same source into a single glance, either by using multiple
      deployments of this charm, or by using a tool such as
      sstream-mirror-glance, and they will not interfere with each
      other.

      Here is a more interesting example value:

          com.example.customstack.{region}:ubuntu:celery-worker

      Currently the only available substitution is "region".  Any
      other attempted substitutions will break the sync script.      
  ssl_ca:
    type: string
    default:
    description: |
      base64-encoded SSL CA to use to verify certificates from keystone and
      glance if using SSL on the services.      
  nagios_context:
    default: "juju"
    type: string
    description: |
      Used by the nrpe-external-master subordinate charm.
      A string that will be prepended to instance name to set the host name
      in nagios. So for instance the hostname would be something like:
          juju-myservice-0
      If you're running multiple environments with the same services in them
      this allows you to differentiate between them.      
  nagios_servicegroups:
    default: ""
    type: string
    description: |
      A comma-separated list of nagios servicegroups.
      If left empty, the nagios_context will be used as the servicegroup

  hypervisor_mapping:
    type: boolean
    default: false
    description: |
      Enable configuration of hypervisor-type on synced images.
      .
      This is useful in multi-hypervisor clouds supporting both LXD and KVM.      
  snap-channel:

  use-internal-endpoints:
    type: boolean
    default: False
    description: |
      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.      
  image_import_conversion:
    type: boolean
    default: False
    description: |
      Enable conversion of images to raw format when uploading images to Glance.
      Only supported when "image_conversion" is enabled in Glance.      
  custom_keyring:
    type: string
    default:
    description: |
      base64-encoded GPG keyring for verifying the simplestreams mirror
      signature. Only required when mirroring a custom user-created repository,
      defaults to /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg which is
      used to sign cloud-images.ubuntu.com.

      Can be produced with the following command:
      gpg --no-default-keyring --keyring gnupg-ring:custom_keyring.gpg \
      --keyserver keyserver.ubuntu.com --recv-keys KEYID
