I made a Distroless Minecraft Server using Nix and Fly.io!

Hello everyone!

To learn Github Actions, Nix Flakes, and Distroless Docker, I used my favorite hosting provider (Fly.io) to deploy a Minecraft server in a Docker container!

My project is open source and reasonably well-documented on GitHub at mboyea/nixflymc.

You probably don’t want to use this.

I don’t recommend that anyone else actually use this unless you want to learn these tools.
To host a Minecraft server on Fly, I would suggest you take a look at this other repository instead that makes use of this Docker image.

Some current known issues with my project:

  • Technically the project isn’t “true distroless” because I use the Busybox base Docker image.
  • The nix run .#uploadWorld script is only functional when manually input line-by-line on the CLI; I couldn’t quickly get ssh working through Nix (though scp does work, so it’s a scripting issue not an authentication issue).
  • The server isn’t configured by Fly to automatically shut off or turn on when it isn’t receiving traffic, but those would be quick changes to Fly.toml.
  • The setup process is fairly involved. At least it’s documented!

Hopefully someone else out there can get something out of this :slight_smile:
Have a great day :yellow_heart:
