<p>I have k8s cluster with three workers and when I explicitly creates the pod, corresponding docker images get downloaded to worker. When I explicitly deletes the pods corresponding docker images are still present on worker nodes. Is this expected case?  </p>

<p>Possibly, considering the <a href="https://kubernetes.io/docs/concepts/cluster-administration/kubelet-garbage-collection/" rel="noreferrer">Kubernetes Garbage collection policy for images</a>:</p>
<blockquote>
<p>Kubernetes manages lifecycle of all images through <code>imageManager</code>, with the cooperation of <code>cadvisor</code>.</p>
<p>The policy for garbage collecting images takes two factors into consideration: <code>HighThresholdPercent</code> and <code>LowThresholdPercent</code>.<br />
Disk usage above the high threshold will trigger garbage collection.<br />
The garbage collection will delete least recently used images until the low threshold has been met.</p>
