# w4 Docker image

Public Linux/amd64 Docker image snapshot created from the `w4` container on 2026-07-18.

## Download and load

```bash
hf download Wolfie-Jr/w4-docker-image w4-docker-image-20260718.tar.zst --local-dir .
zstd -dc w4-docker-image-20260718.tar.zst | docker load
```

The archive restores both `wolfie-jr/w4:20260718` and `wolfie-jr/w4:latest`.

## Run

The original container used host networking, host IPC, X11, and a host data bind mount:

```bash
docker run --rm -it \
  --network host \
  --ipc host \
  -e DISPLAY \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -v /path/to/Data:/workspace/JointCali \
  wolfie-jr/w4:20260718
```

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