Question

Can I use Azure Blob Storage for Kubernetes persistent storage in Hybrid Deployment?

Environment

Container platform: Kubernetes

Answer

Yes, you can use Azure Blob Storage as persistent storage for Kubernetes in Hybrid Deployment. To enable this, first ensure that your Azure Kubernetes Service (AKS) cluster has the Azure Blob CSI driver installed. For more information about the driver, see Azure documentation.

After enabling the driver, configure a Persistent Volume (PV) and a Persistent Volume Claim (PVC) that use the Azure Blob CSI driver.

You can then create a PVC that uses the Azure Blob Storage driver.

Example of Persistent Volume definition for using Azure Blob Storage:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: YOUR_PERSISTENT_VOLUME_NAME
  namespace: YOUR_NAMESPACE
spec:
  capacity:
    storage: 40Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: azureblob-csi
  csi:
    driver: blob.csi.azure.com
    volumeHandle: YOUR_STORAGE_ACCOUNT_NAME/YOUR_BLOB_CCONTAINER_NAME
    volumeAttributes:
      containerName: YOUR_BLOB_CCONTAINER_NAME
    nodeStageSecretRef:
      name: YOUR_SECRET
      namespace: YOUR_NAMESPACE

Example of Persistent Volume Claim definition for using Azure Blob Storage:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: YOUR_PERSISTENT_VOLUME_CLAIM_NAME
  namespace: YOUR_NAMESPACE
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: azureblob-csi
  volumeName: YOUR_PERSISTENT_VOLUME_NAME
  resources:
    requests:
      storage: 40Gi
