I have the qbittorrent web UI running in a separate container that’s attached to my gluetun container. I use the VPN_PORT_FORWARDING_UP_COMMAND option in my gluetun container:

    environment:
      - VPN_PORT_FORWARDING_UP_COMMAND=/bin/sh -c 'wget -O- --retry-connrefused --post-data "json={\"listen_port\":{{PORTS}}}" http://127.0.0.1:8072/api/v2/app/setPreferences 2>&1'

You may have to adjust the http://127.0.0.1:8072/ part based on your setup.

Its literally just the word uinput.

So you can do

sudo echo 'uinput' > /etc/modules-load.d/uinput.conf

Which just tells your system to load the uinput module on startup.

Just to tag on to this, I only needed to enable the uinput module to fix my issue (steam suddenly stopped seeing my 8BitDo controller when it previously could). Didn’t have to do anything with udev rules.
