Forwarding this from upstream kubernetes mailing list.
The TL;DR is that with the release that is due for September 2021
(assuming that happens as planned), Docker will no longer be usable as
a Container Runtime Engine for vanilla Kubernetes. And that's it. All
other usages of Docker remain unchanged.
Given the support cycle of 12 months after a release is out, that
gives us something less than 2 years for having evaluated the
available replacements, settled on one, drafted and implemented a
migration plan. It's a pretty early warning, which is nice.
The above sounds more complicated than it will probably prove, for
what is worth (although the devil is always in the details). As far as
running services in our Wikimedia production kubernetes clusters goes,
we never invested in Docker specific features/customizations on
purpose, choosing to treat it as a replaceable part of the
infrastructure, which should make this easier than initially thought.

Folks,
If you haven't seen the discussions around $SUBJECT, please see [1]
and [2]. Tl;dr Please evaluate and switch to CRI implementations that
are or will be available in the community (like containerd, cri-o
etc).
For those who want to continue to use docker as their runtime, please
see [3] and [4]. There will be changes to how you deploy/run your
clusters as and when Mirantis/Docker folks come up with a migration
plan for a separate (new!) external cri implementation. So watch that
space.
Issues, concerns, we can chat in sig-node slack channel or meetings
(or drop a reply to this note).
Thanks,
Dims

Release Team Manager
Hello all!
Thanks for responding to the call for interest in docker and local
development for MediaWiki (etc!).
I've scheduled a first meeting for this group:
* Thursday February 28th
* 16:00 UTC / 8am Pacific
* Video call: https://meet.google.com/smp-tgoh-uim
** (What's the best way to share a gcal invite with a mailing list?)
Agenda will be fairly basic during the first meeting:
* What is this group? What is a SIG? What are we trying to do? - Greg
* Description/status of the in-flight projects
* Discussion
As a reminder, there is a wiki page[1] and IRC channel[2] which is
already getting some activity!
Thanks!
Greg
