      accessModes: [ "ReadWriteOnce" ]
      resources:

          storage: 100Mi

You can set up the cluster using:

export NODES=$(kubectl get pods -l app=redis-cluster -o jsonpath='{range.items[*]}{.status.podIP}:6379')
kubectl run -it --tty --image=softputer/redis-trib --restart=Never ./redis-trib.rb create $NODES
