Flink Prerequisites: Creating PersistentVolumeClaims

Before deploying Flink modules, create the required PersistentVolumeClaims (PVCs) on the AKS cluster.

About this task

Note:
The access mode ReadWriteMany (RWM) requires a StorageClass backed by a provisioner that supports RWX. Update the namespace from cdp-dev-app to the specific namespace required for the deployment.

Procedure

  1. Create a flink-pvs.yaml file with the following PVC definitions. 
    apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: flink-pvc
  namespace: cdp-dev-app
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: azurefile-csi-premium
  volumeMode: Filesystem
  resources:
    requests:
      storage: 50Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: flink-usrlib-pvc
  namespace: cdp-dev-app
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: azurefile-csi-premium
  volumeMode: Filesystem
  resources:
    requests:
      storage: 50Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: flink-conf-pvc
  namespace: cdp-dev-app
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: azurefile-csi-premium
  volumeMode: Filesystem
  resources:
    requests:
      storage: 50Gi
  2. Apply the PVC manifest. 
    kubectl apply -f flink-pvc.yaml -n <namespace>
