The latest version of Kubernetes Kubernetes v1.20.0-rc.0 is now available. The Kubernetes project plans to deprecate Docker Engine support in the kubelet and support for dockershim will be removed in a future release, probably late next year. The net/net is support for your container images built with Docker tools is not being deprecated and will still work as before.

Even better news however, is that Mirantis and Docker have agreed to partner to maintain the shim code standalone outside Kubernetes, as a conformant CRI interface for Docker Engine. We will start with the great initial prototype from Dims, at https://github.com/dims/cri-dockerd and continuing to make it available as an open source project, at https://github.com/Mirantis/cri-dockerd. This means that you can continue to build Kubernetes based on Docker Engine as before, just switching from the built in dockershim to the external one. Docker and Mirantis will work together on making sure it continues to work as well as before and that it passes all the conformance tests and works just like the built in version did. Docker will continue to ship this shim in Docker Desktop as this gives a great developer experience, and Mirantis will be using this in Mirantis Kubernetes Engine.
