Describe the problem

I've been running Netbird on my Ubuntu 22.04.4 for about two months.
Last week two peers failed to connect and I discovered that the Ubuntu VM was out of disk space. I couldn't do much other than logging in so I had to restore the VM from backup to a week old image and I was then able to resize the volumes.

I have been trying to figure out the culprit (I'm a Linux beginner) and found the following issues:

There is a root_caddy_1 docker image that seems to be saving logs in "debug" mode, which caused the volume to fill up. So far is about 17Gb in size and growing about 1Gb every 36 hrs.
I couldn't find a /etc/docker/daemon.json file to change the log level to "info" or to set logging rotation -- according to some research I did.
If there is not an automated way to clear the logs, what is the recommended way to do this?

Expected behavior

The logs should automatically truncate so the server doesn't run out of disk space.

Are you using NetBird Cloud?
