Using containerd as a Kubernetes Container Runtime

Anthony Nocentino does a switcheroo:

In this post, I’m going to show you how to install containerd as the container runtime in a Kubernetes cluster. I will also cover setting the cgroup driver for containerd to systemd which is the preferred cgroup driver for Kubernetes. In Kubernetes version 1.20 Docker was deprecated and will be removed after 1.22. containerd is a CRI compatible container runtime and is one of the supported options you have as a container runtime in Kubernetes in this post Docker Kubernetes world. I do want to call out that you can use containers created with Docker in containerd.

There are a few steps, but it’s not crazy by any stretch, and that’s part of why the post-Docker-in-Kubernetes world won’t be chaos.
