## Step 1: Create Minio Headless Service
Headless Service controls the domain within which we create StatefulSets. The domain managed by this Service takes the form: `$(service name).$(namespace).svc.cluster.local` (where “cluster.local” is the cluster domain), and the pods in this domain take the form: `$(pod-name-{i}).$(service name).$(namespace).svc.cluster.local`. This is required to get a DNS resolvable URL for each of the pods created within the Statefulset.

This is the Headless service description.
