config.yaml

options:
  driver-source:
    type: string
    default:
    description: |
      Optional configuration to support use of additional sources such as:
        - ppa:myteam/ppa
        - cloud:trusty-proposed/kilo
        - http://my.archive.com/ubuntu main
      The last option should be used in conjunction with the key configuration
      option.
  driver-key:
    type: string
    default:
    description: |
      Key ID to import to the apt keyring to support use with arbitary source
      configuration from outside of Launchpad archives or PPA's.
  use-multipath:
    type: boolean
    default: True
    description: |
      Whether to use a multipath connection for iSCSI or FC in Cinder
      volume service. Enabling multipath for VMs is managed by the
      "use-multipath" option in the nova-compute charm.
  protocol:
    type: string
    default: iscsi
    description: |
      The only supported value is "iscsi"; there may be experimental
      support for the StorPool block client specified by "block" in the
      future.
  volume-backend-name:
    type: string
    description: |
        Volume backend name for the backend. The default value is the
        application name in the Juju model, e.g. "cinder-mybackend"
        if it's deployed as `juju deploy cinder-storpool cinder-mybackend`.
        A common backend name can be set to multiple backends with the
        same characters so that those can be treated as a single virtual
        backend associated with a single volume type.
