Mathieu,
This is configuration I'm using:
links:
# Make sure that the future built-in Docker/containerd sysext images won’t be enabled.
- path: /etc/extensions/docker-flatcar.raw
target: /dev/null
- path: /etc/extensions/containerd-flatcar.raw
target: /dev/null
So apparently we're not using containerd shipped with Flatcar OS. There's containerd v1.7.1, which is shipped by kubespray 2.22 (with k8s 1.26).
And I now see Flatcar ships containerd 1.6.x across all releases, which gives a lot of sense to the compatibility table, putting me on pretty good ground at the same time.
Many thanks for this clarification!
Best,
Piotr Kowalczyk
