@KSDaemon What about docker files?

[KSDaemon]

@ovr good addition, thnx! I forgot about them initially, but they are in my queue!

[ovr]

@KSDaemon, could you please update @types/node in the resolutions section of the packages.json files in the root directory? And regenerate yarn.lock file. Thanks
