• why use two networks, instead they shouldn’t expose any internal ports if using reverse proxy container within compose (I’m using a separate external load balancer/reverse proxy, so I exposed lemmy & lemmy-backend only);
• stuff like hostname: shouldn’t be needed because it matches service name;
• instead of using generic nginx container image with custom nginx.conf you need to place somewhere manually they should pre-build a container which would work OOTB with the compose setup, this would also solve current situation where nginx.conf and compose file are seemingly maintained separately because they don’t match (i had to change one to match the other);
• a minor thing but i would appreciate environment-based setup instead of needing configuration files (lemmy.hjson) on the filesystem (my ansible-based container deploy system has provisions for this stuff, still its something that i’d rather not have to use…);
• in general compose setup feels like development environment because of all the debugging that is enabled, i think it also tries to build one of lemmy components instead of using an image by default;

it’s all minor stuff, really, but it adds up and people who are not particularly savvy might give up on self-hosting lemmy because of if. so some polish and cleanup might be a good idea.

i know there’s an ansible role too but i haven’t looked through it. i have to do way too much ansible code review & refactoring at work. :)
