The reason that 17.12.0 didn't work (in #2427) was because DOCKER_RAMDISK stopped working in containerd: moby/moby#35957 But now that 17.12.1 has been released as "stable", it should be OK ?
Alternatively, one could upgrade from 17.09.0 to 17.09.1 if there is an issue - or wanting to play it safe...
Kubernetes still doesn't "support" anything beyond Docker 17.03, as pointed out so nicely by
kubeadm
:WARNING: docker version is greater than the most recently validated version.
So let's go with the latest (stable), unless there is a reason to stick with the earlier (stable) Sep version ?
