Actually gluetun is working as expected, I can't fix anything really I think.

Maybe have a look at https://github.com/qdm12/gluetun/wiki/TUN-device-errors see if anything can help in there?

As per the wiki I'm running as root.

did you start it with sudo or as root user?

I've tried both, as root and with sudo.

Sorry I lost track of this.
Did you figure out why cannot create TUN device file node: operation not permitted failed? Are you sure you passed --cap-add=NET_ADMIN? If so, please create a bug issue sharing your config, logs, OS, kernel etc. asked by the fields to fill up.

For anyone else having the same issue In a docker compose file, pass the ENV variables as: "- PGID=0 -PUID=0" so the container runs as root.

Meh the container runs as root already (must for vpn and firewall), PGID and PUID is used only for subprocesses (openvpn, unbound) and files written (other than the tun device), so I doubt this would make any difference with the tun device creation.
