What’s actually happening here is that Dockershim is being removed from Kubelet as early as v1.23 release, which removes support for Docker as a container runtime as a result.

The image that Docker produces isn’t really a Docker-specific image -- it’s an OCI (Open Container Initiative) image. Any OCI-compliant image, regardless of the tool you use to build it, will look the same to Kubernetes. Both containerd and CRI-O know how to pull those images and run them. This is why we have a standard for what containers should look like.
