Custom Images

By default, Rook will deploy the latest stable version of the Ceph CSI driver. Commonly, there is no need to change this default version that is deployed. For scenarios that require deploying a custom image (e.g. downstream releases), the defaults can be overridden with the following settings.

The CSI configuration variables are found in the rook-ceph-operator-config ConfigMap. These settings can also be specified as environment variables on the operator deployment, though the configmap values will override the env vars if both are specified.

kubectl -n $ROOK_OPERATOR_NAMESPACE edit configmap rook-ceph-operator-config

The default upstream images are included below, which you can change to your desired images.

ROOK_CSIADDONS_IMAGE: "quay.io/csiaddons/k8s-sidecar:v0.4.0"

Use default images

If you would like Rook to use the default upstream images, then you may simply remove all variables matching ROOK_CSI_*_IMAGE from the above ConfigMap and/or the operator deployment.

Verifying updates

You can use the below command to see the CSI images currently being used in the cluster. Note that not all images (like volumereplication-operator) may be present in every cluster depending on which CSI features are enabled.

kubectl --namespace rook-ceph get pod -o jsonpath='{range .items[*]}{range .spec.containers[*]}{.image}{"\n"}' -l 'app in (csi-rbdplugin,csi-rbdplugin-provisioner,csi-cephfsplugin,csi-cephfsplugin-provisioner)' | sort | uniq

The default images can also be found with each release in the images list
