Chapter 3. Edit the Environment File
The environment file contains the back end settings you want to define. It also contains other settings relevant to the deployment of the Shared File System service. For more information about environment files, see Environment Files (from the Director Installation and Usage guide).
This release includes an integrated environment file for defining a CephFS back end. This file is located in the following path of the undercloud node:
This file provides default settings for deploying a Shared File System service.
Create an environment file which will contain the settings necessary for your environment — namely,
~/templates/manila-cephfsnative-config.yaml. The following snippet shows the default values used by the director when deploying the Shared File System service:
parameter_defaults: # 1 ManilaCephFSNativeBackendName: cephfsnative ManilaCephFSNativeDriverHandlesShareServers: false # 2 ManilaCephFSNativeCephFSConfPath: '/etc/ceph/ceph.conf' # 3 ManilaCephFSNativeCephFSAuthId: 'manila' # 4 ManilaCephFSNativeCephFSClusterName: 'ceph' ManilaCephFSNativeCephFSEnableSnapshots: true
parameter_defaultsheader signifies the start of your configuration. Specifically, it allows you to override default values set in
resource_registry. This includes values set by
OS::Tripleo::Services::ManilaBackendCephFs, which sets defaults for a CephFS back end.
false, the driver will not handle the lifecycle of the share server.
ManilaCephFSNativeCephFSConfPath:sets the path to the configuration file of the Ceph cluster.
ManilaCephFSNativeCephFSAuthId:is the Ceph auth ID that the director will create for share access.
