Cluster Metering and Cost Management

Prerequisites

  • OpenShift 4.6 on VMware 6.7 U3+ or 7.0
  • VMware Cloud Native Storage to support CNS CSI

OpenShift Internal Registry for vSphere

After you install the cluster, you must create storage for the registry Operator.

For VMware environement, we usually don't have Object Storage available for Registry, so we will use RWO PV storage for single registry instance here

Procedure

  1. Create image-registry-storage PVC. The example use default thin storageclass, please change per strageclass available in your environment. 
    cat <<EOF | oc create -f -
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: image-registry-storage
  namespace: openshift-image-registry
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 100Gi
  storageClassName: thin
  volumeMode: Filesystem
EOF
  2. Apply block registry storage for VMware vSphere 
    oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"managementState":"Managed","rolloutStrategy":"Recreate","storage":{"pvc":{"claim":"image-registry-storage"}}}}'
