I am defining

1: a Deployment for a pod running the official rabbitmq image

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: rabbitmq-deployment
spec:
  replicas: 1
  template:
    metadata:
      labels:
        els-pod: rabbitmq
    spec:
      containers:
      - image: rabbitmq
        name: rabbitmq
        ports:
        - containerPort: 5672
      restartPolicy: Always

2: a Service as a wrapper, so that the pod(s) are discoverable

apiVersion: v1
kind: Service
metadata:
  name: rabbit
spec:
  ports:
  - name: rabbit-port
    port: 5672
    targetPort: 5672
  selector:
      els-pod: rabbit

I am logged in a container(pod):

/# nslookup rabbit
Server:     100.64.0.10
Address:    100.64.0.10#53

Name:   rabbit.default.svc.cluster.local
Address: 100.71.124.222

However:

nc rabbit 5672 &> /dev/null; echo $?
1

The port is NOT open/accessible!

Is sth wrong with my manifests?
