Hi @Newyean

running graphical applications in a Docker container is not a common thing and the workarounds of getting an X11 server to run in Docker is complicated (have a look her: GitHub - mviereck/x11docker: Run GUI applications and desktops in docker and podman containers. Focus on security.)

Cheers,
Simon
