Testing a Graphical Program

First get your IPv4 address:

Windows:

ipconfig

Under the Ethernet adapter vEthernet (WSL): header there should be a line containing IPv4 Address.

Linux:

ip route

The first line should contain the IP address.

In the terminal run:

docker build -f Dockerfile.xeyes . -t xeyes
docker run --rm --name xeyes -e DISPLAY=<your_IPv4_address>:0.0 xeyes:latest

Or use a pre-built image: https://hub.docker.com/r/openiss/openiss-xeyes

docker run --rm --name xeyes -e DISPLAY=<your_IPv4_address>:0.0 openiss/openiss-xeyes:F22-01

xeyes

If you see the xeyes program appear, that means graphics are working. (The xeyes example is not technically OpenGL, but more so X11 but allows for a quick test of graphical display from Linux to Windows).
