    # --- To run `# docker` scripts (bash scripts with a `# docker` annotation) on
    #     this worker: comment the `image` line above and uncomment the *-full
    #     image below. Each docker job then runs in its OWN ephemeral rootless
    #     podman, torn down with the job — no dind sidecar, no host Docker socket,
    #     your scripts unchanged. The *-full image also bundles the heavier runtimes
    #     (Java, .NET, Ruby, R, Rust, Ansible, Nushell). `# docker` scripts are
    #     auto-tagged `docker` (served by default workers); to send them to a
    #     dedicated/bigger group instead, run a worker with WORKER_TAGS=docker. ---
    # image: ghcr.io/windmill-labs/windmill-full:main   # windmill-ee-full:main for EE
    # On old kernels (<5.13, no native rootless overlay) podman needs fuse-overlayfs;
    # expose the device then (harmless to keep; auto-provided by `privileged` if the
    # host has it):
    # devices:
    #   - /dev/fuse
    # Keep this worker running as ROOT (the default — do NOT set `user: 1000`):
    # windmill itself drops the per-job podman to a non-root uid, so containers are
    # rootless AND the worker's own secrets in /proc (DATABASE_URL etc.) stay
    # root-owned, unreadable by a `docker run --pid=host` container. (NB: this does
    # not confine the container's filesystem view — a `# docker` script can still
    # `docker run -v` to read WORLD-READABLE host state: other job dirs' world-readable
    # files, the dep cache, and world-readable /proc like process cmdlines/args — though
    # NOT 0400 files like /proc/<pid>/environ (env secrets stay safe; don't pass secrets
    # as args). So treat docker workers as trusted-tenant / dedicate them on shared
    # fleets.) Docker jobs use disk like any other job (no docker-specific cap); bound
    # it at the infra level (e.g. a sized volume for /tmp/windmill) for all jobs.
    # If you enable nsjail (DISABLE_NSJAIL=false or job isolation = nsjail), per-job
    # podman is NOT auto-provided for docker jobs — nsjail signals "fully sandbox jobs"
    # and the podman daemon runs outside the jail, so docker jobs then require an
    # explicit DOCKER_HOST or a separate non-nsjail worker group. (nsjail is off by
    # default; the default worker uses unshare, so docker works out of the box here.)
    # To use an external/host Docker daemon instead (legacy): set DOCKER_HOST or mount
    # /var/run/docker.sock.
