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 in 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:
/usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml
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:
/home/stack/templates/manila-cephfsnative-config.yaml
parameter_defaults: # 1 ManilaCephFSNativeBackendName: cephfsnative ManilaCephFSNativeDriverHandlesShareServers: false # 2 ManilaCephFSNativeCephFSConfPath: '/etc/ceph/ceph.conf' # 3 ManilaCephFSNativeCephFSAuthId: 'manila' # 4 ManilaCephFSNativeCephFSClusterName: 'ceph' ManilaCephFSNativeCephFSEnableSnapshots: true
