Redis Cluster requires at least 3 master nodes, so we have 6 replicas here ( 3 master / 3 slave )

```bash

kubectl apply -f statefulset.yml

kubectl apply -f service.yml

```

## Make cluster

You should scale the cluster up or down manually

### Get cluster nodes

```bash

kubectl get pods -l app=redis-cluster -o jsonpath='{range.items[*]}{.status.podIP}:6379 '

```

Now we are going to create the cluster ( assign master/slave roles, distribute slot maps) using the `redis-cli --cluster create` script.  

Since we are going create 3 masters cluster with 3 dedicated slaves, the `--cluster-replicas 1` flag is passed.

```bash

kubectl exec -it redis-cluster-0 -- redis-cli --cluster create --cluster-replicas 1 <<< node list from previous command >>>

```

Or you can merge command like this :

```bash

kubectl exec -it redis-cluster-0 -- redis-cli --cluster create --cluster-replicas 1 $(kubectl get pods -l app=redis-cluster -o jsonpath='{range.items[*]}{.status.podIP}:6379 ')

```
