Docker makes it easy to set up and remove apps. Simply (a) create folder, (b) download/copy-paste the docker-compose template into the folder, © run ‘docker-compose up -d’ and watch the magic happen. And if you want to remove the image just do a ‘docker-compose down’ followed by ‘docker system prune -a’ and poof, it’s gone (although this command will remove any docker container that’s not running, so be careful! (Otherwise remove manually with ‘docker ps’ and then ‘rm name-of-container’). I’m in a similar boat to you and my L2 now runs Plex (media), Immich (photos), Mealie (recipes), Kavita (books), OwnCloud (files), PaperlessNgx (important documents) and Joplin (notes). It also runs Nginx Proxy Manager so I can access some of these apps outside my network (you can grab free domains from duckdns.org), and the others I access via Tailscale for extra security (highly recommend looking it up). Enjoy your journey. It gets very addictive!
