I have minimal Ubuntu installation in my container and I want to have Xserver running. I need XServer, because my app requires meshlabserver, which itself needs Xserver.
I installed xserver-xorg and all other packages, but when I try to start X in container via
/usr/bin/X :0
it says:
Fatal server error:
(EE) xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)
What am I doing wrong? How do I start X server?
UPDATE:
related question: Host screen turns off when I start X server in docker container
In my case it works nicely when I start container in privileged mode:
docker run --privileged
So XServer gets access to some devices from host (including /dev/tty0).
In general case it is a bad idea to run container in privileged mode, but in my case it's okay.
To avoid using --privileged you can also try --device option of docker run command.
