# This is a sample configmap that helps define a Ceph cluster configuration
|
|
# as required by the CSI plugins.
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
# Lets see the different configuration under config.json key.
|
|
# The <cluster-id> is used by the CSI plugin to uniquely identify and use a
|
|
# Ceph cluster, the value MUST match the value provided as `clusterID` in the
|
|
# StorageClass
|
|
# The <MONValue#> fields are the various monitor addresses for the Ceph cluster
|
|
# identified by the <cluster-id>
|
|
# If a CSI plugin is using more than one Ceph cluster, repeat the section for
|
|
# each such cluster in use.
|
|
# To add more clusters or edit MON addresses in an existing configmap, use
|
|
# the `kubectl replace` command.
|
|
# The <rados-namespace> is optional and represents a radosNamespace in the pool.
|
|
# If any given, all of the rbd images, snapshots, and other metadata will be
|
|
# stored within the radosNamespace.
|
|
# NOTE: The given radosNamespace must already exists in the pool.
|
|
# NOTE: Make sure you don't add radosNamespace option to a currently in use
|
|
# configuration as it will cause issues.
|
|
# The field "cephFS.subvolumeGroup" is optional and defaults to "csi".
|
|
# The <netNamespaceFilePath#> fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the CSI plugin to execute the rbd map/unmap and mount -t commands in the
|
|
# network namespace specified by the <netNamespaceFilePath#>.
|
|
# If a CSI plugin is using more than one Ceph cluster, repeat the section for
|
|
# each such cluster in use.
|
|
# NOTE: Changes to the configmap is automatically updated in the running pods,
|
|
# thus restarting existing pods using the configmap is NOT required on edits
|
|
# to the configmap.
|
|
|
|
# Lets see the different configuration under cluster-mapping.json key.
|
|
# This configuration is needed when volumes are mirrored using the Ceph-CSI.
|
|
# clusterIDMapping holds the mapping between two clusterId's of storage
|
|
# clusters.
|
|
# RBDPoolIDMapping holds the mapping between two poolId's of storage clusters.
|
|
# CephFSFscIDMapping holds the mapping between two FscId's of storage
|
|
# clusters.
