[preflight] WARNING: docker version is greater than the most recently validated version. Docker version: 17.03.1-ce. Max validated version: 1.12
[preflight] Some fatal errors occurred:

[preflight] If you know what you are doing, you can skip pre-flight checks with --skip-preflight-checks

I've been using it with --skip-preflight-checks and haven't encountered any issues so far.

From a user point of view the error message clearly states that this is a serious (fatal) problem resulting in cluster initialization failure. This is my very first attempt to try the kubernetes and I have no idea about the impact of missing cgroups: memory on the setup. I will risk switching --skip-preflight-checks on this Jessie box equipped with Xenial repository for kubernetes but I'm afraid that I may hit other missing dependencies without being aware of.

@errordeveloper, is this an already known issue scheduled for fixation? Clear and accurate log messages are invaluable specifically for newcomers.

--EDIT--

Seems that skipping preflight checks resulted in #228 now :-( [apiclient] Created API client, waiting for the control plane to become ready
