as same host directory is not shared between
the cephfs and the rbd plugin pod. we need
to keep the netNamespaceFilePath separately
for both cephfs and rbd. CephFS plugin will
use this path to execute mount -t commands.

# 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 "rbd.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 "cephFS.netNamespaceFilePath" fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the CephFS CSI plugin to execute the mount -t in the
|
|
# network namespace specified by the "cephFS.netNamespaceFilePath".
|
|
# The "rbd.netNamespaceFilePath" fields are the various network namespace
|
|
# path for the Ceph cluster identified by the <cluster-id>, This will be used
|
|
# by the RBD CSI plugin to execute the rbd map/unmap in the
|
|
# network namespace specified by the "rbd.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.
