ENTRYPOINT ["i3"]

Thank you for sharing this!
Where should i put the "docker run [image_name]" command? i tried putting it in my .xinitrc file but it did not work. (getting a blank screen)
Obviously, running from inside Gnome gives me "i3: cannot openm display"
Is it even possible to use i3 via docker?
