      for precise but is provided in the Ubuntu cloud archive.
  key:
    type: string
    default:

      Key ID to import to the apt keyring to support use with arbitary source
      configuration from outside of Launchpad archives or PPA's.
  harden:

      to run. Supported modules currently include os, ssh, apache and mysql.
  config-flags:

      User provided Ceph configuration. Supports a string representation of

      WARNING: this is not the recommended way to configure the underlying
      services that this charm installs and is used at the user's own risk.
      This option is mainly provided as a stop-gap for users that either
      want to test the effect of modifying some config or who have found
      a critical bug in the way the charm has configured their services
      and need it fixed immediately. We ask that whenever this is used,
      that the user consider opening a bug on this charm at
      http://bugs.launchpad.net/charms providing an explanation of why the
      config was needed so that we may consider it for inclusion as a
      natively supported config in the charm.
  port:
    type: int
    default:
    description: |
      The port that the RADOS Gateway will listen on.
      .
      The default is 80 when no TLS is configured and 443 when TLS is
      configured.
  prefer-ipv6:
    type: boolean
    default: False
    description: |
      If True enables IPv6 support. The charm will expect network interfaces
      to be configured with an IPv6 address. If set to False (default) IPv4
      is expected.
      .
      NOTE: these charms do not currently support IPv6 privacy extension. In
      order for this charm to function correctly, the privacy extension must be
      disabled and a non-temporary address must be configured/available on
      your network interface.
  pool-prefix:
    type: string
    default:
    description: |
      DEPRECATED, use zone instead - pool name can be inherited from the zone config
      option. The rados gateway stores objects in many different pools. If you
      would like to have multiple rados gateways each pointing to a separate
      set of pools set this prefix. The charm will then set up a new set of pools.
      If your prefix has a dash in it that will be used to split the prefix into
      region and zone. Please read the documentation on federated rados gateways
      for more information on region and zone.
  restrict-ceph-pools:
    type: boolean
    default: False
    description: |
      Optionally restrict Ceph key permissions to access pools as required.
  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 RGW pools. Note that once the RGW pools have been
      created, changing this value will not have any effect (although it can be
      changed in ceph by manually configuring your ceph cluster).
  rgw-buckets-pool-weight:
    type: int
    default: 20
    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 amount of data loaded
      into the RADOS Gateway/S3 interface is expected to be reserved for or
      consume 20% of the data in the Ceph cluster, then this value would be
      specified as 20.
  rgw-lightweight-pool-pg-num:
    type: int
    default: -1
    description: |
      When the Rados Gatway is installed it, by default, creates pools with
      pg_num 8 which, in the majority of cases is suboptimal. A few rgw pools
      tend to carry more data than others e.g. .rgw.buckets tends to be larger
      than most. So, for pools with greater requirements than others the charm
      will apply the optimal value i.e. corresponding to the number of OSDs
      up+in the cluster at the time the pool is created. For others it will use
      this value which can be altered depending on how big you cluster is. Note
      that once a pool has been created, changes to this setting will be
      ignored. Setting this value to -1, enables the number of placement
      groups to be calculated based on the Ceph placement group calculator.
  relaxed-s3-bucket-names:
    type: boolean
    default: false
    description: |
      Enables relaxed S3 bucket names rules for US region buckets. This
      allows for bucket names with any combination of  letters, numbers,
      periods, dashes and underscores up to 255 characters long, as long
      as bucket names are unique and not formatted as IP addresses.

    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
      the data pool used by the application.  The metadata pool is always

      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
      durability estimator. For instance, if c=2, 2 OSDs can be down

      (clay plugin - d) Number of OSDs requested to send data during
      recovery of a single chunk. d needs to be chosen such that

  sync-policy-state:
    type: string
    default: enabled
    description: |
      This setting is used by the primary ceph-radosgw in multi-site
      replication.

      By default, all the buckets are synced from a primary RGW zone to the
      secondary zone. This config option allows us to have selective buckets
      sync. If this is set, it will be used as the default policy state for
      all the buckets in the zonegroup.

      Valid values are:
        * enabled - sync is allowed and enabled
        * allowed - sync is allowed
        * forbidden - sync is not allowed
  sync-policy-flow-type:

      This setting is used by the secondary ceph-radosgw in multi-site

      set on the primary ceph-radosgw.

      Valid values are:
        * directional - data is only synced in one direction, from primary to
          secondary.
        * symmetrical - data is synced in both directions.
  namespace-tenants:
    type: boolean
    default: False
    description: |
      Enable tenant namespacing. If tenant namespacing is enabled, keystone
      tenants will be implicitly added to a matching tenant in radosgw, in
      addition to updating the catalog URL to allow radosgw to support
      publicly-readable containers and temporary URLS. This namespacing
      also allows multiple tenants to create buckets with the same names,
      as the bucket names are namespaced into the tenant namespaces in the
      RADOS gateway.

      This configuration option will not be enabled on a charm upgrade, and
      cannot be toggled on in an existing installation as it will remove
      tenant access to existing buckets.

      compressible.
      'aggressive' means use compression unless clients hint that
      data is not compressible.
      'force' means use compression under all circumstances even if the clients
      hint that the data is not compressible.

    type: float
    default:
    description: |
      The ratio of the size of the data chunk after compression relative to the

    type: boolean
    default: false
    description: |
      If true, radosgw is configured to allow the use of virtual hosted bucket
      name. This also requires the creation of a DNS CNAME to point all wildcard
      subdomains (*.radosgw.domain) to the radosgw IP (or VIP). The host name part
      (radosgw.domain) is taken from os-public-hostname so it must have a value too.
