Earlier today people started mentioning the news that Kubernetes 1.20 deprecated support for Docker. But what does that mean?

Kubernetes will still run Docker images just fine, since Docker images conform to the OCI standard. But Kubernetes recommends using a more lightweight container runtime, like containerd, or CRI-O, to actually run containers inside a Kubernetes cluster.

So don’t fret, this change likely won’t affect you no matter what tools you use, unless you regularly install new Kubernetes clusters and set up Docker with them. And in that case, it should be a simple fix—install containerd instead of Docker on your Kubernetes nodes!
