OSBot fails to start without an X server

[Timothyofawesome]

I'm currently trying to get osbot to run inside of either a docker container or my linux server from ssh. I keep getting the error below. If I run it on my local linux machine it runs perfectly fine ( has an X server/graphical interface running). Any ideas on how to resolve this? I am using the same java installation between my working machine and docker. Setting the DISPLAY variable causes it to crash with null pointer exceptions.

Update: got it working!

Dockerfile:

ENTRYPOINT ["./entrypoint.sh"]

 

Entrypoint.sh:

java -jar /root/OSBot/osbot.jar -allow nointerface,lowcpu -login redacted -bot redacted -script Skeleton:1 -world 301
cat /proc/$(ps aux | grep "/root/OSBot/osbot.jar" | grep -v grep -m 1 | awk '{print $2}')/fd/1

Xvfb runs an X server with a display. 

Most of this was stolen from:

 

Just had to figure out the xserver stuff.
