The system shuts down right after the start

[SoerenSofke]

I am using Docker (Version 2.0.0.0-win81 (29211)) on Windows 10. Following exactly your example "Getting started" provided in README.md, I got the following log, mentioning "s6-applyuidgid: fatal: unable to exec /startapp.sh: No such file or directory":

[services.d] done.
14/12/2018 20:36:41 X DAMAGE available on display, using it for polling hints.
14/12/2018 20:36:41 To disable this behavior use: '-noxdamage'
14/12/2018 20:36:41
14/12/2018 20:36:41 Most compositing window managers like 'compiz' or 'beryl'
14/12/2018 20:36:41 cause X DAMAGE to fail, and so you may not see any screen
14/12/2018 20:36:41 updates via VNC. Either disable 'compiz' (recommended) or
14/12/2018 20:36:41 supply the x11vnc '-noxdamage' command line option.
14/12/2018 20:36:41 X COMPOSITE available on display, using it for window polling.
14/12/2018 20:36:41 To disable this behavior use: '-noxcomposite'
14/12/2018 20:36:41
14/12/2018 20:36:41 Wireframing: -wireframe mode is in effect for window moves.
14/12/2018 20:36:41 If this yields undesired behavior (poor response, painting
14/12/2018 20:36:41 errors, etc) it may be disabled:
14/12/2018 20:36:41 - use '-nowf' to disable wireframing completely.
14/12/2018 20:36:41 - use '-nowcr' to disable the Copy Rectangle after the
14/12/2018 20:36:41 moved window is released in the new position.
14/12/2018 20:36:41 Also see the -help entry for tuning parameters.
14/12/2018 20:36:41 You can press 3 Alt_L's (Left "Alt" key) in a row to
14/12/2018 20:36:41 repaint the screen, also see the -fixscreen option for
14/12/2018 20:36:41 periodic repaints.
14/12/2018 20:36:41 GrabServer control via XTEST.
14/12/2018 20:36:41
14/12/2018 20:36:41 Scroll Detection: -scrollcopyrect mode is in effect to
14/12/2018 20:36:41 use RECORD extension to try to detect scrolling windows
14/12/2018 20:36:41 (induced by either user keystroke or mouse input).
14/12/2018 20:36:41 If this yields undesired behavior (poor response, painting
14/12/2018 20:36:41 errors, etc) it may be disabled via: '-noscr'
14/12/2018 20:36:41 Also see the -help entry for tuning parameters.
14/12/2018 20:36:41 You can press 3 Alt_L's (Left "Alt" key) in a row to
14/12/2018 20:36:41 repaint the screen, also see the -fixscreen option for
14/12/2018 20:36:41 periodic repaints.
14/12/2018 20:36:41
14/12/2018 20:36:41 XKEYBOARD: number of keysyms per keycode 7 is greater
14/12/2018 20:36:41 than 4 and 51 keysyms are mapped above 4.
14/12/2018 20:36:41 Automatically switching to -xkb mode.
14/12/2018 20:36:41 If this makes the key mapping worse you can
14/12/2018 20:36:41 disable it with the "-noxkb" option.
14/12/2018 20:36:41 Also, remember "-remap DEAD" for accenting characters.
14/12/2018 20:36:41
14/12/2018 20:36:41 X FBPM extension not supported.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval. It should work with any VNC viewer. Try it by running:

x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.

Issue solved:

line ending set to UNIX-format (LF) instead of Windows (CR LF)

Great Docker image!
