metadata:
  name: sitting-duck
  labels:
    name: sitting-duck
spec:
  replicas: 1
  selector:
    name: sitting-duck
  template:
    metadata:
      labels:
        name: sitting-duck
    spec:
      containers:
      - name: duck
        image: gosharplite/duck:v4
        command:
        - /duck
        - -delay
        - "62"

   "apiVersion":"v1",
   "metadata":{
      "name":"sitting-duck",
      "labels":{
         "name":"sitting-duck"
      }
   },
   "spec":{
      "ports": [
        {
          "port":80
        }
      ],
      "selector":{
