I set it to debug at somepoint and forgot maybe? Idk, but why the heck does the default config of the official Docker is to keep all logs, forever, in a single file woth no rotation?

Feels like 101 of log files. Anyway, this explains why my storage recipt grew slowly but unexpectedly.

You should always setup logrotate. Yes the good old Linux logrotate...

    We should each not have to configure log rotation for every individual service. That would require identify what and how it logs data in the first place, then implementing a logrotate config. Services should include a reasonable default in logrotate.d as part of their install package.

  • Docker services should let docker handle it, and the user could then manage it through Docker or forward to some other logging service (syslog, systemd, etc). Processes in containers shouldn't touch rotation or anything, just log levels and maybe which types of logs go to stdout vs stderr.

    Imho it’s because docker does away with (abstracts?) many years of sane system administration principles (like managing logfile rotations) that you are used to when you deploy bare metal on a Debian box. It’s a brave new world.

    It's because with docker you don't need to do log files. Logging should be to stdout, and you let the host, orchestration framework, or whoever is running the container so logs however they want to. The container should not be writing log files in the first place, containers should be immutable except for core application logic.

    Or you can use Podman, which integrates nicely with Systemd and also utilizes all the regular system means to deal with log files and so on.

    Good suggestion, although I do feel it always comes back to this “many ways to do kind of the same thing” that surrounds the Linux ecosystem. Docker, podman, … some claim it’s better, I hear others say it’s not 100% compatible all the time. My point being more fragmentation.

    100 ways to configure a static ip.
    Why does it need that? At least one per distro controlled by the distro-maintainers.

    I disagree with this, container runtimes are a software like all others where logging needs to be configured. You can do so in the config of the container runtime environment.

    Containers actually make this significantly easier because you only need to configure it once and it will be applied to all containers.

    You are right and as others have pointed out correctly it’s Nextcloud not handling logging correctly in a containerized environment. I was ranting more about my dislike of containers in general, even though I use the technology (correctly) myself. It’s because I am already old on the scale of technology timelines.

    Everything I hear about Nextcloud scares me away from messing with it.

    for some helpful config, the below is the logging config I have and logs have never been an issue.

    You can even add 'logfile' => '/some/location/nextcloud.log', to get the logs in a different place

      'logtimezone' => 'UTC',
      'logdateformat' => 'Y-m-d H:i:s',
      'loglevel' => 2,
      'log_rotate_size' => 52428800,

    Reminds me of when my Jellyfin container kept growing its log because of something watchtower related. Think it ended up at 100GB before I noticed. Not even debug, just failed updates I think. It's been a couple of months.

    Wow, thanks for the heads up! I use Nextcloud AIO and backups take VERY long. I need to check about those logs!

    Don't know if I'm just lucky or what, but it's been working really well for me and takes good care of itself for the most part. I'm a little shocked seeing so many complaints in this thread because elsewhere on the Internet that's the go-to method.
