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
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:
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-cluster if any of the following is true:
velerois enabled. If you applied config overrides for
veleroto use a storage that is external to your cluster, then you do not need Ceph to be installed.
