<p>I have Question on pod termination on using image: kodekloud/throw-dice </p>

<p>pod-defintion.yml</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: throw-dice-pod
spec:
  containers:
  -  image: kodekloud/throw-dice
     name: throw-dice
  restartPolicy: Never
</code></pre>

<p>I have checked the steps in <a href="https://hub.docker.com/r/kodekloud/throw-dice/dockerfile" rel="nofollow noreferrer">DockerFile </a>. It runs <a href="https://github.com/kodekloudhub/throw-dice/blob/master/throw-dice.sh" rel="nofollow noreferrer">throw-dice.sh</a> which randomly returns number in between 1 - 6.</p>

<p>let's consider first time container return 3, so how below pod is terminated ? where is the condition defined in the pod level it suppose to terminate if script return number is !6.</p>

<p>Below steps were performed to execute pod-definition.yml</p>

<pre><code>master $ kubectl create -f /root/throw-dice-pod.yaml

<p>The dockerfile has <code>ENTRYPOINT sh throw-dice.sh</code> which means execute the script and then the container terminates automatically. If you want the container to keep running you need to start a long running process for example a java process <code>ENTRYPOINT ["java", "-jar", "/whatever/your.jar"]</code></p>
