brickd and brickv containers for Raspberry Pi/gokrazy

This repo builds container images for:

• ghcr.io/tonobo/brickd-docker:latest — Tinkerforge Brick Daemon
• ghcr.io/tonobo/brickd-docker/brickv:latest — Brick Viewer with VNC/noVNC

Both images are arm64-only and install packages from the official Tinkerforge APT repository.

Usage with Podman (e.g., on gokrazy)

Brick Daemon:

podman run --network host --rm \
  --device /dev/bus/usb \
  --device /dev/gpiochip0 --device /dev/gpiochip1 \
  -v /perm/brickd-config:/config:ro \
  ghcr.io/tonobo/brickd-docker:latest

If your HAT exposes more nodes, add them with --device (e.g., /dev/spidev0.0, /dev/i2c-1). If needed, run fully privileged with --privileged and bind /sys to expose the HAT EEPROM/DT to brickd.

Brick Viewer (VNC/noVNC):

podman run --rm --network host \
  -e XVFB_RES=1280x800x24 \
  -p 5900:5900 -p 6080:6080 \
  ghcr.io/tonobo/brickd-docker/brickv:latest

Access noVNC at http://<pi>:6080, or VNC at <pi>:5900.
