Hello! I have been struggling through a few tutorials on getting a lemmy instance to work correctly when setup with Docker. I have it mostly done, but there are various issues each time that I do not have the knowledge to properly correct. I am familiar with Docker, and already have an Oracle VPS set up on ARM64 Ubuntu. I already have portainer and an NGINX proxy set up and working okay. I have an existing lemmy instance “running” but not quite working. My best guess here would be to have someone assist with setting up the docker-compose to work with current updates/settings, as well as the config.hjson.
TIA, and I cant wait to have my own entry into the fediverse working right!
hi, can you post your docker-compose.yaml, nginx config and screenshots/logs of failures?
(1/2) Alright, thanks for helping.
docker-compose.yml

I did not customize the conf that it installed with, and only used the UI to set up the proxy host and SSL, both of which are working (front end, at least.). The config seems to be unrelated on this, however I can share it if the rest of the information below is not enough.
nginx config and lemmy.hjson would be useful as well
Sure thing. lemmy.hjson:

There is no volume or link for a conf file from host:container, so I am just grabbing from the default area /etc /nginx/nginx.conf:

I may be mistaken in my choice of proceeding, but as many are reporting, the install guide provided docker-compose and general docker instructions dont quite seem to work as expected. I have been trying to piecemeal this together, and the Included lemmy nginx service container was completely excluded (edited out/deleted) once I had the standalone nginx-proxy-manager setup and working for regular 80,443 ->1234 proxy requests to the lemmy-ui container.
Does the lemmy nginx have a specific role or tie in? I am still fairly new to reverse proxying in general.
yeah, nginx config for lemmy is not very straighforward. you need to mimic this:
worker_processes 1; events { worker_connections 1024; } http { upstream lemmy { server "lemmy:8536"; } upstream lemmy-ui { server "lemmy-ui:1234"; } server { listen 1236; server_name localhost; # frontend location / { set $proxpass "http://lemmy-ui"; if ($http_accept = "application/activity+json") { set $proxpass "http://lemmy"; } if ($http_accept = "application/ldr+json; profile=\"https://www.w3.org/ns/activitystreams\"") { set $proxpass "http://lemmy"; } if ($request_method = POST) { set $proxpass "http://lemmy"; } proxy_pass $proxpass; rewrite ^(.+)/+$ $1 permanent; # Send actual client IP upstream proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } # backend location ~ ^/(api|pictrs|feeds|nodeinfo|.well-known) { proxy_pass "http://lemmy"; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; # Add IP forwarding headers proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } }also - can you check if all containers are running? just do
docker-compose psin the lemmy dir.All containers are running. I handle them with Portainer, though I build the stack from the CLI in the lemmy dir, so Portainer cant fully manage them. Reboots and logs and networking and such work fine though.
As for the nginx config, the nginx proxy manager I use currently has all proxy-host/settings setup from the webGUI, where I use the GUI to set up the proxy host information and SSL information. I did no manual edits to any configurations or settings of the container during or after compose. Only GUI actions. When looking at the nginx.conf I replied with here (my current conf), I do not see anything related to that proxy host I created from the GUI. I am not sure if that is normal or not, or if I maybe have a wrong .conf included here.
With that in mind, would you suggest I simply overwrite and/or add your snippet to my existing conf file?
try to look here for the config file:
include /etc/nginx/conf.d/*.conf; include /data/nginx/default_host/*.conf; include /data/nginx/proxy_host/*.conf; include /data/nginx/redirection_host/*.conf; include /data/nginx/dead_host/*.conf; include /data/nginx/temp/*.conf;btw, i think port in lemmy.bulwarkob.com:1236 in docker-compose is not needed for you, should be just lemmy.bulwarkob.com
(2/2) I am able to connect to my lemmy UI site and navigate. When I try to view “Communities”, I get stuck with just a spinning wheel, and never get results. Same for trying to login or create an account. I have checked logs for all the containers, and so far the only error is on the lemmy_lemmy_1 container, which is the following (Error is the last entry, labelled DEBUG):
