The huge success of Docker in energizing the tech community around containers has been truly amazing to see. As containers are the foundation of Kubernetes, it goes hand in hand that Docker was a core part of the platform. As Kubernetes matured, and the needs of the community and our customers grew, the tight coupling of Docker to Kubernetes through dockershim (the interface between the Kubernetes platform and the Docker runtime) needed to evolve. On 2 December 2020, with the release of Kubernetes 1.20, Kubernetes announced it is deprecating Docker as a container runtime, through the use of dockershim, in a future release of Kubernetes.
We work very closely with the community through our participation in the Kubernetes Special Interest Groups (SIG) from Storage, to Windows and everything in between and I'd like to thank both the community and our engineering teams for the work to get to this milestone.
