I tried this but it’s not working on my site. So basically I am using the default nginx and doin the ssl offloading with Traefik

You can simply use traefik as ssl offloading pointing to the nginx container in the lemmy stack. That’s what I am doing with docker swarm. I have not figured out how to get rid of that additional nginx

A way to migrate to a smaller “instance” is by using a synology nas with enough bays. You could split them by using ssd hdd raids and dockerize all applications or even create vm on it

could you paste your docker-compose file ? This would help a bit.
