Hello Friends:

I need `JupyterHub` to launch `JupyterLab` containers in `privileged` mode. So in `jupyterhub_config.py` (the **HUB** configuration file, not the **LAB** configuration file), I added the following entry:

```auto
c.DockerSpawner.extra_host_config = {
           "privileged" : True,
           "devices" : ["/sys/fs/cgroup:/sys/fs/cgroup:ro",],
           "tmpfs" : {"/tmp":"", "/run":"", "/run/lock":""}, }

```

After implementing that (and restarting), and then launching a **LAB** server, I don’t see a `--privileged` option in the output of `docker ps --no-trunc`. As well, the output of `docker inspect jupyter-jdoe | grep -i priv` shows `Privileged` as `false`.

Does anyone know how to properly implement this? I think I’m close, but I need help.

Thank you!

Sigh! I determined what the issue was. The above is correct. The issue is that, while I correctly set `c.DockerSpawner.extra_host_config` as shown, I accidentally clobbered that `dict()` later in the code by overwriting it versus `.update()`ing it. 🤡 Apologies for the false alarm. Hoping others find the question and method useful though. 😊
