<p>I've created a JOB pod with 2 INIT containers
At pod creation, my job completed successfully but no sign of the init containers</p>

<p>To me, the job should have wait for the completion of the 2 init containers before starting</p>

<p>My job blueprint (taken from Kubernetes documentation) in case you'd like to reproduce the problem</p>

<pre><code>apiVersion: batch/v1
kind: Job
metadata:
  name: pi
annotations:
  pod.beta.kubernetes.io/init-containers: '[
    {
      "name": "init-myservice",
      "image": "busybox",
      "command": ["sh", "-c", "until nslookup myservice; do echo waiting for myservice; sleep 2; done;"]
    },
    {
      "name": "init-mydb",
      "image": "busybox",
      "command": ["sh", "-c", "until nslookup mydb; do echo waiting for mydb; sleep 2; done;"]
    }
    ]'

<p>NO SIGN OF THE INIT CONTAINERS !!!</p>

<p>My Environment:
--- Kubernetes version (use kubectl version):
Client Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.2+43a9be4", GitCommit:"43a9be4", GitTreeState:"clean", BuildDate:"2017-04-20T15:38:11Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}

<p>I'm working in a Cluster from OpenStack</p>

<p>OS is Red Hat Enterprise Linux Server 7.3 (Maipo)</p>

<p>Thanks in advance for any help.</p>

<p>Try adding the annotation to the spec template rather than the Job object:</p>

<pre><code>apiVersion: batch/v1
kind: Job
metadata:
  name: pi
spec:
  template:
    metadata:
      name: pi
    annotations:
      pod.beta.kubernetes.io/init-containers: '[
        {
          "name": "init-myservice",
          "image": "busybox",
          "command": ["sh", "-c", "until nslookup myservice; do echo waiting for myservice; sleep 2; done;"]
        },
        {
          "name": "init-mydb",
          "image": "busybox",
          "command": ["sh", "-c", "until nslookup mydb; do echo waiting for mydb; sleep 2; done;"]
        }
        ]'
    spec:
      containers:
      - name: pi
        image: perl
        command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
      restartPolicy: Never
</code></pre>
