Headless/Offscreen rendering

Part of my deployment scenario requires Headless/Offscreen rendering (in this case, inside of Docker containers) - for example, as might be used for rendering movies or streaming games from the server. I'm not seeing a documented way to do this at the moment.
I know this is possible in the general sense (UnrealEngine, for one example), but not whether Kha supports this, or whether it was a planned feature.

The issue names no files, tests, or entry points. First determine whether Kha or Armory supports headless/offscreen rendering inside Docker; done requires documenting a supported setup or clarifying whether this remains a planned feature.
