--- # 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. data: config.json: |- [ { "clusterID": "<cluster-id>", "rbd": { "netNamespaceFilePath": "<kubeletRootPath>/plugins/rbd.csi.ceph.com/net", "radosNamespace": "<rados-namespace>", }, "monitors": [ "<MONValue1>", "<MONValue2>", ...
