Devcontainer

  1. Install Docker: Ensure that Docker is installed on your machine. You can download and install Docker Desktop from the official Docker website.

  2. Configure X Server: On Windows, you will need an X server to display the Pygame window. VcXsrv is a common choices for Windows. Install and configure an X server to allow connections from your Docker container.

  3. Start .devcontainer: Open the project in Visual Studio Code and click on the green "Remote-Containers" icon in the bottom left corner. Select "Reopen in Container" to start the container.

Here is a step-by-step guide:

X11 GUI support for the .devcontainer

Unfortunately, the remote-containers extension does not support GUI applications out of the box. However, you can still run GUI applications in the container by connecting to an X server running on your host machine. We need to identify our host OS manually and follow the appropriate steps.

Install X Server on Windows

  1. Download and Install VcXsrv:
    • Download VcXsrv from sourceforge.net.
    • Install VcXsrv using the default settings.
    • Run VcXsrv, selecting the "Multiple windows" option, and ensure the "Disable access control" option is checked.

Inside the docker container, the DISPLAY environment variable should be set to host.docker.internal:0.0 to connect to the X server running on your Windows host.

X11 on ubuntu

enable x11 access for the docker container

# on the host system

# if docker requires sudo
sudo xhost +local:root

# if docker does not require sudo
xhost +local:docker

In the docker container, set the DISPLAY environment variable to:

# inside the container
export DISPLAY=:0

This command sets the DISPLAY environment variable to use the X server running on your host.

You should see the Pygame window appear on your Windows desktop, managed by the X server.
