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:

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_processes 1;
events {
worker_connections 1024;
}
http {
#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"
# "POST:application/activity+json"
#
# You can see some basic match tests in this regex101 matching this configuration
# https://regex101.com/r/vwMJNc/1
#
# Learn more about nginx maps here http://nginx.org/en/docs/http/ngx_http_map_module.html
map "$request_method:$http_accept" $proxpass {
# If no explicit matches exists below, send traffic to lemmy-ui
default "http://lemmy-ui";
# GET/HEAD requests that accepts ActivityPub or Linked Data JSON should go to lemmy.
#
# These requests are used by Mastodon and other fediverse instances to look up profile information,
# discover site information and so on.
"~^(?:GET|HEAD):.*?application\/(?:activity|ld)\+json" "http://lemmy";
# All non-GET/HEAD requests should go to lemmy
#
# Rather than calling out POST, PUT, DELETE, PATCH, CONNECT and all the verbs manually
# we simply negate the GET|HEAD pattern from above and accept all possibly $http_accept values
"~^(?!(GET|HEAD)).*:" "http://lemmy";

Any chance you can post your config, internal nginx conf, postgresql.conf, and the swag conf? I'm trying to do the same thing and I've been running into various errors. And I've yet to find a good unraid guide for lemmy. Would appreciate!
