# v4 Docker image

Public Linux/amd64 Docker image snapshot created from the `v4` container on 2026-07-18.

## Download and load

```bash
hf download Wolfie-Jr/v4-docker-image v4-docker-image-20260718.tar.zst --local-dir .
zstd -dc v4-docker-image-20260718.tar.zst | docker load
```

The archive restores both `wolfie-jr/v4:20260718` and `wolfie-jr/v4:latest`.

## Run

The original container used host networking, host IPC, privileged mode, X11, USB access, and a host data bind mount:

```bash
docker run --rm -it \
  --network host \
  --ipc host \
  --privileged \
  -e DISPLAY \
  -e QT_X11_NO_MITSHM=1 \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -v /dev/bus/usb:/dev/bus/usb \
  -v /path/to/Data:/workspace/JointCali \
  wolfie-jr/v4:20260718
```

Replace `/path/to/Data` with the appropriate host directory. Bind-mounted host data is not part of the image.
