- $enable_v2_messenger
    Enables Ceph messenger version 2 ( >= Nautilus release)
- $enable_libvirt_rbd
    Configure Ceph for libvirt based RBD clients
    Currently requires openstack::nova::compute::service::ocata::stretch
- $osd_hosts [Optional]
    Hash that defines the ceph object storage hosts, and public and private IPv4 information
- $radosgw_port [Optional]
    Listen port for the rados gateway. Gateway will only be configured if this is set.
- $keystone_internal_uri [Optional]
    URI for internal keystone service. Only used if radosgw_port is set.
- $radosgw_service_user [Optional]
    Name of radosgw service user (probably 'swift'). Only used if radosgw_port is set.
- $radosgw_service_user_project [Optional]
    Project for radosgw service user (probably 'service'). Only used if radosgw_port is set.
- $radosgw_service_user_password [Optional]
    Password for radosgw service user. Only used if radosgw_port is set.

  • enable_libvirt_rbd (Boolean)
  • enable_v2_messenger (Boolean)
  • mon_hosts (Hash[String,Hash])
  • cluster_networks (Array[Stdlib::IP::Address])
  • public_networks (Array[Stdlib::IP::Address])
  • fsid (String)
  • osd_hosts (Optional[Hash[String,Hash]]) (defaults to: {})
  • radosgw_port (Optional[Stdlib::Port]) (defaults to: 0)
  • keystone_internal_uri (Optional[String]) (defaults to: '')
  • radosgw_service_user (Optional[String]) (defaults to: '')
