### Step Two: Turn up the master service.
A Kubernetes 'service' is named load balancer that proxies traffic to one or more containers. The services in a Kubernetes cluster are discoverable inside other containers via environment variables. Services find the containers to load balance based on task labels. The task that you created in Step One has the label "name=redis-master", so the corresponding service is defined by that label. Create a file named redis-master-service.json that contains:
