Sway on Pod-Arcade

Usage

The Pod-Arcade Sway container can be accessed via VNC using port 6900:5900. For web access, port-forward 7900:7900 to use noVNC. When using this with pod-arcade, this port isn't needed, as you'll access it through the pod-arcade/server webpage.

Running with Hardware Acceleration

Use this command to run the container with hardware acceleration. It requires mounting the /dev/dri directory to /host/dev/dri in the container.

docker run --rm \
 -it \
 --name "pod-arcade-sway" \
 --privileged \
 -v /dev/dri:/host/dev/dri \
 -p 6900:5900 \
 ghcr.io/pod-arcade/sway

Running Without Hardware Acceleration

Use this command to run the container without hardware acceleration.

docker run --rm \
 -it \
 --name "pod-arcade-sway" \
 --privileged \
 -p 6900:5900 \
 ghcr.io/pod-arcade/sway

Hardware Acceleration Configuration

The container's behavior for hardware acceleration depends on the mounted volumes:

MKNOD Mode

  • Mount Path: /dev/dri -> /host/dev/dri/
  • Requires CAP_MKNOD capability.
  • Best for high compatibility and shared mount paths.
  • Recreates device nodes inside the container with 777 permissions.

ADD_GROUP Mode

NOTE: If you're using the ADD_GROUP mode, you must specifically set DRI_DEVICE_MODE=ADD_GROUP. This is to prevent accidentally enabling hardware acceleration when none was requested. When running docker in privileged mode, it automatically mounts the GPU device into the container.

  • Mount Path: /dev/dri -> /dev/dri/
  • No special permissions needed.
  • Creates new groups inside the container with the same GID as the host, and adds the ubuntu user to them.
  • Suitable for single-container setups.
  • Not ideal for multi-container environments with shared GPU access.

Environment Variables

Set custom resolutions for the container (default is 1280x720):

export RESOLUTION="1280x720"
