Howdy! Forgive the link to the site that must not be named, but I found this guide to get it hosted using portainer and Nginx proxy manager. Perhaps some of the config and notes over there will help ya. Or perhaps it will make it worse since you may not have the same setup that I do haha.
Seems like you are building Lemmy from source as it has "build:" specified. I personally use "image: dessalines/lemmy:0.17.4" to avoid building Lemmy from source.
I always see docker compose files like this as a starting point rather than the best way to do things, haha.
so much debugging enabled
Yeah, the log level is pretty excessive, though lemmy is still pretty young software-wise so they are probably doing it to make sure they can get good bug reports from users. At least they are necessarily showing you how you can change those levels yourself if you are unhappy with their suggested settings.
two networks for whatever reason
Two networks isn't strictly necessary, but it is generally a good practice to isolate things that don't need to talk to each other at a network/vlan/whatever level. IMO it's not particularly useful since docker compose makes a somewhat isolated network by default (have to be on the same box and know the IPs to hit it). I would just use ports to expose the LB, also is less powerful when they're exposing postgres like they are.
bespoke logging setup instead of just using system default
Unless it has changed the "default" logging for docker retains a stupid amount of logs. I literally filled disks because of this until I figured out what was happening. IMO this is actually a very good production-oriented change.
host mounted directories instead of docker volumes
Maybe a controversial opinion, but I actually want to control where the disks are being mounted very explicitly (pictrs on NAS, pg on local fast disk, etc) and find this far easier to do with host directories than volumes.
Thanks! I just tried the docker-compose.yml you shared and I am getting the follwoing error:
ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for networks: 'lemmyinternal'
Unsupported config option for services: 'pictrs'
If you're not using arm remove the arm tags. Not sure about the network issue as u should be able to declare networks in compose easily. Id check if some formatting got messed up in copying it over as the yaml is usually whitespace sensitive. Is there more to the pictrs error because that image is pretty basic and jus pulls it doen
Honestly, i don't think anyone knows what is happening what is going on inside the docker-compose files i set my instance up with 0.17.4/prod file with some tweaks.
Gotta stick with the 1st rule of engineering: "If it works, do not touch it"
Also i don't know if my full works, cause i can federate with everybody except lemmy.ml (which i guess is a error on their end?)
