title: What does it mean that Kubernetes removed support for Docker but supports containerd (which is part of Docker)?
body: <p>What does it mean that Kubernetes removed support for Docker but supports containerd. Docker developed containerd and uses it for managing containers.</p>
  <p>Are there 2 different containerd?</p>
  <ol>
  <li>one that is supported by kubernetes</li>
  <li>another one which is used by docker</li>
  </ol>
  <p>If not, then why kubernetes cannot talk/use to containerd used by the Docker daemon?</p>
