| # 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. | |
