### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

kubectl get svc --namespace {{ .Release.Namespace }} -l app={{ template "minio.fullname" . }}

Note that the public IP may take a couple of minutes to be available.

You can now access MinIO server on http://<External-IP>:9000. Follow the below steps to connect to MinIO server with mc client:

You may also setup etcd with TLS following this documentation [here](https://coreos.com/etcd/docs/latest/op-guide/security.html)

### 3. Setup MinIO with etcd
