Desktop GUI Workspace

This image is using Ubuntu 22.04 and provides a desktop environment that users can access from a web browser. There are a few components that are running to get this working:

• XVFB (Creates a headless X11 server)
• x11vnc (Provides the VNC server)
• Websockify (Provides a TCP VNC -> Websocket layer)
• Custom Node server (Wraps the VNC stuff and serves the client pages)

Building

docker build . -t "prairielearn/workspace-desktop"
