How do you use GUI apps with Docker? Do you have an X server (or equivalent) running on the Docker container that you connect to remotely?
On a local machine using X or XWayland you can pass in the DISPLAY environment variable and X socket. Any program that expects a local X server will just connect to that over a unix socket like normal. It took a little trial and error but there are some guides online.
