Controller Configurations

Within the PowerProtect Data Manager UI, you can add controller configurations for a Kubernetes cluster.

The following controller configuration keys can be specified when adding or editing the Kubernetes cluster asset source Advanced Options.

Table 1. Controller configuration keys
Key	Value	Description
k8s.ppdm.autoenable.cbt	true or false	This setting is only applicable for PVCs provisioned by the VMware CSI driver. PowerProtect Data Manager enables changed block tracking (CBT) by default on First Class Disks (FCDs). Set the value to `false` to disable this behavior and perform only full backups.
k8s.ppdm.support.volumeGroup	true or false	PowerProtect Data Manager uses volumegroup snapshots by default for PVCs provisioned by the PowerFlex CSI driver that have volume group snapshotting enabled. Set the value to `false` if you do not want to use volumegroupsnapshot.
k8s.ppdm.readonly.storageclass	`storageclass1`,`storageclass2`	A comma separated list of storageclass names. During the backup for these storage classes, PowerProtect Data Manager uses ReadOnlyMany (ROX) mode to create a temporary PVC from the snapshot. NOTE The provisioner for these storage classes should support ROX mode.
k8s.docker.registry	`fqdn`:`port`	The fully qualified domain name (FQDN) of the internal registry for air gapped clusters. For example, `artifacts.example.com` or `artifacts.example.com:8446`.
k8s.image.pullsecrets	`pull secret name`	Name of the image pull secret that you create in the powerprotect namespace and the velero-ppdm namespace when containers are hosted in an internal registry and the registry requires authentication.
k8s.ppdm.create.timeout	`timeout in seconds`	The length of time that the powerprotect-controller waits for the CSI snapshot and temporary PVC to be created during the backup before timing out. The default value is 600 seconds.
k8s.velero.exclude.resources	`resourcetype1`,`resourcetype2`	A comma separated list of Kubernetes resource types to be excluded for all backups in the Kubernetes cluster.

NOTE When updates to Advanced Options result in changes to the configuration of PowerProtect Data Manager components in the Kubernetes cluster, the interruption of running Kubernetes protection activities can occur.
