Execute the following commands to install: 

kubectl create namespace middleware
kubectl apply -f es.yaml

Verify Deployment

  • Check Pod Status
kubectl get pods -n middleware -l app=elasticsearch

Successful result:

NAME           READY   STATUS    RESTARTS   AGE
es-cluster-0   1/1     Running   0          24h

Configure Accounts

Create Admin Account (Authentication Required)

Use the kubectl command-line client to log in interactively to the deployed ES service and execute the operation to create a superuser.

kubectl exec -ti -n middleware es-cluster-0 \
    -- bin/elasticsearch-users useradd copriwolf -p sayHi2Elastic -r superuser

Change Elastic Password

Note

The {"password": "4dIv4VJQG5t5dcJOL8R5"} part highlighted can be modified with your own password.

kubectl exec -ti -n middleware es-cluster-0 -- curl -u copriwolf:sayHi2Elastic \
       -XPUT "http://localhost:9200/_xpack/security/user/elastic/_password?pretty" \
       -H 'Content-Type: application/json' \
       -d '{"password": "4dIv4VJQG5t5dcJOL8R5"}'

How to Uninstall

kubectl delete -f es.yaml
kubectl delete -n middleware pvc data-es-cluster-0
