    ```bash
    docker system df # See what's eating space

    docker ps
    docker ps -a
    docker container ls

    docker stop <container> # SIGTERM, then SIGKILL after 10s (use -t N to change)
    docker kill <container> # immediate SIGKILL

    docker system prune # Remove stopped containers, dangling images, unused networks
    docker system prune -a --volumes # Same as above plus all images not used by any container and unused volumes (volumes may contain DB/data)

    docker image prune # Only dangling
    docker image prune -a # All
    docker container prune # Stopped containers
    docker volume prune # Only dangling volumes


    docker images -a # List images
    docker rmi $(docker images -q) # remove all images not in use; add --force as needed

    docker volume ls
    docker volume ls -qf dangling=true | xargs -r docker volume rm # Remove volumes (data loss if used)

    docker network ls
    docker network prune
    ```

    # Docker Compose
    ```bash
    docker compose up
    docker compose ps # see running services
    docker compose stop # graceful stop all services in this stack
    docker compose down # stop + remove containers (keeps volumes unless --volumes)
    ```
