Prerequisites

Ensure that you have installed the Coherence Operator by following the instructions here.

Installation Steps

Change to the samples/coherence-deployments/extend/default directory. Ensure that you have your maven build environment set for JDK8, and build the project.
```
$ mvn clean install
```

Install the Coherence cluster.

$ helm install \
   --namespace sample-coherence-ns \
   --name storage \
   --set clusterSize=3 \
   --set cluster=storage-tier-cluster \
   --set imagePullSecrets=sample-coherence-secret \
   --set logCaptureEnabled=false \
   coherence/coherence

Once the installation is complete, get the list of pods by using the kubectl command:

$ kubectl get pods -n sample-coherence-ns

All the three storage-coherence pods should be running and ready, as shown in the output:

NAME                  READY   STATUS    RESTARTS   AGE
storage-coherence-0   1/1     Running   0          4m
storage-coherence-1   1/1     Running   0          2m
storage-coherence-2   1/1     Running   0          1m

Port forward the proxy port on the storage-coherence-0 pod using the kubectl command:
```
$ kubectl port-forward -n sample-coherence-ns storage-coherence-0 20000:20000
```

Connect via CohQL and run the following commands:

$ mvn exec:java

Run the following CohQL commands to insert data into the cluster.

insert into 'test' key('key-1') value('value-1');

select key(), value() from 'test';
Results
["key-1", "value-1"]

select count() from 'test';
Results
1

Uninstall the Chart

Run the following command to delete the chart installed in this sample.

$ helm delete storage --purge

Before starting another sample, ensure that all pods are removed from the previous sample. To remove coherence-operator, use the helm delete command.
