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!

    Sure thing. lemmy.hjson:

    spoiler
    {
      # for more info about the config, check out the documentation
      # https://join-lemmy.org/docs/en/administration/configuration.html
      # only few config options are covered in this example config
    
      setup: {
        # username for the admin user
        admin_username: "noUsrHere"
        # password for the admin user
        admin_password: "noPassHere"
        # name of the site (can be changed later)
        site_name: "Bulwark of Boredom"
      }
    
      # the domain name of your instance (eg "lemmy.ml")
      hostname: "lemmy.bulwarkob.com"
      # address where lemmy should listen for incoming requests
      bind: "0.0.0.0"
      # port where lemmy should listen for incoming requests
      port: 8536
      # Whether the site is available over TLS. Needs to be true for federation to work.
      tls_enabled: true
    
      # pictrs host
      pictrs: {
        url: "http://pictrs:8080/"
        api_key: "API_KEY"
      }
    
      # settings related to the postgresql database
      database: {
        # name of the postgres database for lemmy
        database: "noDbHere"
        # username to connect to postgres
        user: "noUsrHere"
        # password to connect to postgres
        password: "noPassHere"
        # host where postgres is running
        host: "postgres"
        # port where postgres can be accessed
        port: 5432
        # maximum number of active sql connections
        pool_size: 5
      }
    }
    

    I am not certain if I am somehow getting the wrong location of the config in the container. 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;

                  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 ps in 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

                I appreciate your patience and clear assistance.

                conf.d/* has two configurations that appear to be some form of default. default.conf and production.conf. production.conf is only for the admin GUI. default.conf:

                Container has a volume set /lemmy/docker/nginx-proxy-manager/data:/data

                I have those folders and more, and they DO seem to have the correct custom item.

                Specifically, in the proxy_host folder I have a configuration for the proxy host I set up (1.conf) in the GUI:

                  okay, i don’t know how npm works, could you check this tutorial to see if you have set it up similarly?

                  https://youtu.be/6lQFZvCCe7U

                  also - check docker-compose.yml settings to remove port for lemmy host and i think you need to set use https to true as it is provided by npm

                    I actually started with this tutorial a few days ago after failing the official guide. I followed it but was unable to get it running due to unexpected errors. Im guessing this tutorial is somewhat out of date. Ive made progress since using that guide though so I will see if I can pull any useful bits out of it later today and continue.

                    Worst case, I could also just ditch NPM if I can get another NGINX set up in a way that you might know how to do correctly.

                    Hey, if you still feel like helping out :D

                    Ive been through a boatload of changes today since earlier. Ive rebuilt using mostly the provided yml in the official guide, and after some tweaking, almost everything is working. The internal proxy is now working, and the containers are working amongst themselves fully as far as I can tell. I do not know how to setup a web facing reverse proxy in a way that works around the internal proxy already running (other than the already in place NPM). I turned the NPM back on, and was able to get it working to reach the site, however I cannot reach any other communities from within my site. I believe the reverse proxy NPM is just not set up right. Error message in lemmy:
