Nice! Downloaded and configured. Looks like a great gboard replacement

SHUN THE NON-BELIEVER! _shunnnn…

Added internal nginx and external proxy configs to a reply. I didn’t make any changes to the postgres config.

Hope it helps

This is the nginx.conf file for my external proxy:

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name ;

    include /config/nginx/ssl.conf;

    location / {
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
#        set $upstream_app lemmy;
        set $upstream_app proxy;
        set $upstream_port 8536;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
#        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-Real-IP $remote_addr;
#        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size 50M;            
    }
}

access_log /var/log/nginx/access.log combined;

You’ll need to change  to the appropriate value. I’m forwarding requests to the proxy container referenced by the compose file

My nginx.conf for lemmy-nginx is below, sorry if it’s a bit messy. I prefer to comment than remove working config. You’ll have to change

    worker_connections 1024;

#Beginning of kbin fix
# We construct a string consistent of the "request method" and "http accept header"
    # and then apply soem ~simply regexp matches to that combination to decide on the
    # HTTP upstream we should proxy the request to.
    #
    # Example strings:
    #
    #   "GET:application/activity+json"
    #   "GET:text/html"

Commenting to vouch for lcs. It works well and isn’t resource heavy

Adding on to the comment by @[email protected], Lemmy Community Seeder can help with populating your instance.

Isn’t kbin compatible with both Lemmy and Mastodon? I see tons of Mastodon content in the Microblog tab currently

Check out lemmy community seeder

I was able to get it running with the docker compose CA app and minimal changes to the official docker-compose file (docs). I’m running swag in front of the lemmy proxy with no issues with federation. Ibracorp’s tutorial can help with the compose plugin

You’ll need to make sure the volume locations and ports are appropriate for your unraid install. You’ll also have to update your domain in the compose file. I’m running swag so I needed to make a new reverse proxy configuration per the official docs.

My compose file is below:
