Hi guys, I am trying to bring a lemmy instance up but I have no idea why it freezes on “building lemmy”

This is what I get: https://i.imgur.com/GjcHPkd.png

    re: container logs issue, the proper fix is setting this once in daemon.json (which is what you did) and fixing this issue node-wide instead of adding custom logging into compose files, unless the situation requires it (we had an application which had to use gelf for, oh god) which isn’t the case here. i just have an ansible role to deploy docker which configures logging, among other things.

    agree that multiple networks may have a use but definitely not in this particular case.

    I always see docker compose files like this as a starting point

    same here, unfortunately not everyone has necessary expertise to do that, default setup linked on the project page shouldn’t be this half-baked.

    also, unless they fixed it already, 3 days ago compose file and nginx.conf had mismatching ports so it would just never work ootb.

      I mean, either of us could be contributing to fix the docs/compose file on github instead of arguing agreeing about it here on reddit lemmy.

      fixing this issue node-wide instead of adding custom logging into compose files

      Yeah, they should probably have that in the docs as part of the “install docker” step, IIRC such a change takes restarting the docker daemon (which requires restarting all containers), which kinda sucks. I see having this in the compose as a way to prevent people who won’t follow the instructions closely from shooting themself in the foot, and then if you know what you’re doing you’ll probably just strip that stuff out of the config anyways.

      default setup linked on the project page shouldn’t be this half-baked

      Agreed, though it does seem like it is continuing to evolve. As someone who works in DevOps I have learned not to expect devs to worry about or be interested in the actual running of their software. This project is very immature and experience a significant spkie in users, I think stumbling through things at this point is fine as long as lessons are learned and improvements are made (which seems to be happening).

      I mean, when I installed lemmy I am pretty sure a significant number of these things (debug settings, logging) weren’t even in the example compose file. That is still a pretty funny oversight regardless.
