Rook Ceph in DKP - Prerequisites

Important information you should know prior to using Rook Ceph in DKP

The Ceph instance installed by DKP is intended only for use by the logging stack and velero platform applications.

If you have an instance of Ceph that is managed outside of the DKP lifecycle, see Bring Your Own Storage to DKP Clusters.

If you do not plan on using any of the logging stack components such as grafana-loki or velero for backups, then you do not need Rook Ceph for your installation and you can disable it by adding the following to your installer config file:

CODE
apiVersion: config.kommander.mesosphere.io/v1alpha1
kind: Installation
apps:
  ...
  ...
  grafana-loki:
    enabled: false
  ...
  rook-ceph:
    enabled: false
  rook-ceph-cluster:
    enabled: false
  ...
  velero:
    enabled: false
...

You must enable rook-ceph and rook-ceph-cluster if any of the following is true:

  • If grafana-loki is enabled.

  • If velero is enabled. If you applied config overrides for velero to use a storage that is external to your cluster, then you do not need Ceph to be installed.

For more information about Ceph, refer to the following:

See Rook Ceph Configuration for information on how you can configure Ceph for you Ceph Envirnoment.
