> kubectl port-forward --address 0.0.0.0 service/azblob-service 20001:10000

4. Eecode azblob-service IP address to base64

Get the cluster IP of azblob-service

> kubectl get svc
NAME             TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)     AGE
kubernetes       ClusterIP   10.43.0.1     <none>        443/TCP     6h3m
azblob-service   ClusterIP   10.43.81.75   <none>        10000/TCP   13m

Edcode the IP address to base64

> echo -n "http://10.43.81.75:10000/" | base64

apiVersion: v1
data:
  AZBLOB_ACCOUNT_KEY: RWJ5OHZkTTAyeE5PY3FGbHFVd0pQTGxtRXRsQ0RYSjFPVXpGVDUwdVNSWjZJRnN1RnEyVVZFckN6NEk2dHEvSzFTWkZQVE90ci9LQkhCZWtzb0dNR3c9PQ==
  AZBLOB_ACCOUNT_NAME: ZGV2c3RvcmVhY2NvdW50MQ==
  AZBLOB_ENDPOINT: aHR0cDovLzEwLjQzLjgxLjc1OjEwMDAwLw==

6. Create container demo

Perform below command to create Azure container demo

> az storage container create -n demo --connection-string "DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://0.0.0.0:20001/devstoreaccount1;"

After the command, should see below reply

{
  "created": true
}

7. Set Longhorn backuptarget

Set backup-target to azblob://demo@core.windows.net/

Set backup-target-credential-secret to azblob-secret
