Thank you for this! I am working on it now. Having issues with installing docker as it seems like their repo for Raspbian is actually empty… I suppose I can just tell it to use an Ubuntu repo and put in the most recent Ubuntu version name so it pulls from there. I’ll let you know how it all goes.

Okay so here are the contents of the nginx.conf file:

worker_processes 1;
events {
    worker_connections 1024;
}
http {
upstream lemmy {
    # this needs to map to the lemmy (server) docker service hostname
    server "lemmy:8536";
}
upstream lemmy-ui {
    # this needs to map to the lemmy-ui docker service hostname
    server "lemmy-ui:1234";
}

server {
    # this is the port inside docker, not the public one yet
    listen 80;
    # change if needed, this is facing the public web
    server_name localhost;
    server_tokens off;

    gzip on;
    gzip_types text/css application/javascript image/svg+xml;
    gzip_vary on;

    # Upload limit, relevant for pictrs
    client_max_body_size 20M;

    add_header X-Frame-Options SAMEORIGIN;
    add_header X-Content-Type-Options nosniff;
    add_header X-XSS-Protection "1; mode=block";

    # frontend general requests
    location / {
        # distinguish between ui requests and backend
        # don't change lemmy-ui or lemmy here, they refer to the upstream definitions on top
        set $proxpass "http://lemmy-ui";

        if ($http_accept = "application/activity+json") {
          set $proxpass "http://lemmy";
        }
        if ($http_accept = "application/ld+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 common stuff
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        # 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;
    }
}

}

Okay so I don’t see

build:
  context: ../
  dockerfile: docker/Dockerfile

in the docker compose file anywhere. Where should I then place

image: dessalines/lemmy:<tag>

?
