Adds container image and accompanying GitHub Workflow to build the image and deploy to GitHub's own registry.

It's been a full year, but I wonder if we could use Nix for this? Tried building a simple image with it, and it resulted in a 298M tarball?

Nix is great for reproducible builds, but Docker and Nix serve different purposes and work well together. Docker provides a reproducible runtime environment for deployment, while Nix ensures your builds are deterministic. Using Nix to build your application and Docker to package it gives you the strengths of both: reliable builds and consistent deployment across machines. Even if a Nix-built image is larger, Docker’s portability and isolation make it the right tool for shipping and running applications.

you can already build docker image with nix

There's also work in progress to publish the nix-built OCI containers to ghcr, but that's not my area of expertise so i'll defer :)
