### Deploy a sample Zookeeper cluster with Ephemeral storage

Create a Yaml file called `zk.yaml` with the following content to install a 3-node Zookeeper cluster.

```yaml
apiVersion: "zookeeper.pravega.io/v1beta1"
kind: "ZookeeperCluster"
metadata:
name: "example"
spec:
replicas: 3
storage:
storagetype: ephemeral
