  • First check if the wireguard family exists
  • If not, try loading the wireguard kernel module
  • If it succeeds, re-check the wireguard family exists

I just testet it (with multiple reboots) and I can report that it works perfectly.

Don't forget to add the following to the Wiki and/or example docker-compose.yml:

cap_add:
  - SYS_MODULE
volumes:
  - /lib/modules:/lib/modules:ro

Awesome thanks!

Don't forget to add the following to the Wiki and/or example docker-compose.yml

I would rather keep the default docker-compose.yml as it is, since the error you see is a bit niche, and newer kernels are likely to have wireguard built-in, or systems configured to load wireguard at boot. Speaking of which, wouldn't it be possible (I guess too late for me haha) to just configure a unit service to modprobe wireguard before launching docker on boot ? That feels maybe a bit more appropriate (and worth mentioning in the wiki) 🤔

Back to the internal module probing, I would like to handle different errors and log info messages depending on the error; what error message is logged (debug level) when:

  1. SYS_MODULE is absent, bind mount is absent
  2. SYS_MODULE is absent, bind mount is present
  3. SYS_MODULE is present, bind mount is absent

So I can handle the error and log a more useful info message such as 'bind mount missing', 'sys_module capability missing' in case the module prob fails.

Yes, in hindsight a service unit to load the module would have been less work.

I don't get any different error messages with LOG_LEVEL=debug depending on what is present/absent:

  1. SYS_MODULE is absent, bind mount is absent:

That's odd, I pushed another commit d1a86a2 adding more debug logs.

At the very least, it should log

wireguard family not found, trying to load wireguard kernel module

and then either

failed loading wireguard kernel module: error message
# or
wireguard kernel module loaded successfully

Please try again (repull the image) - no need to try all of them if you don't get the debug logs mentioned

qdm12 commented Aug 4, 2023

Thanks! I added custom error messages mentioning the missing bind mount or missing capability depending on the error message obtained; these will be logged at debug level still since there are some systems out there without wireguard at all, and I don't want to spam them with useless information.

Our discussion is more or less sumarized here: https://github.com/qdm12/gluetun-wiki/blob/main/setup/advanced/wireguard.md#load-wireguard-kernel-module

It will be up to the user to either use the Gluetun modprobe custom code, or use modprobe wireguard at boot.
