Self-Hosted Main

I have Portainer running several self-hosted apps, but I am having a hard time getting a recipe and food planner app like Mealie or Tandoor to work. I'm sure some of you have gotten this to work, and I'm hoping you'll share how you do it.

Some context: I have nothing exposed to the Internet, and I just have a Wireguard VPN set up on my phone and laptop for if I want to access my self-hosted apps while away from my home. All the docs and examples I can find for Mealie and Tandoor assume that I am exposing them to the Internet in some way, and that is not my use case.

I access my self-hosted apps via their IP and port number (and I have them organized in a dashboard for ease of use.) I know this is not the most common way, but I know others do this, too. So that's why I am asking for some of you lovely people to share your docker compose files for self-hosting Mealie or Tandoor with no domain name, proxy manager, etc. Just connection via IP address and port number from the local network.

P.S. I am fine with either using SQLite to avoid needing a seperate database, or including something like Postgres inside the same Docker Compose file, either way.
