nix-fly-template

This is a barebones template to build an application with Nix and deploy it on Fly.io.

You can take a look at this barebones application serving this README.md on two environments:

• Staging: https://nix-fly-template-staging.fly.dev
• Production: https://nix-fly-template.fly.dev

How to use

1. Use this template to create a repository for your app
2. Launch a Fly app for each environment you want (prod, staging, etc.)
3. Add your Fly apps' names in fly.nix, and configure .github/workflows/fly.yml to deploy to your apps
4. Add a FLY_API_TOKEN secret to your GitHub repo containing a Fly API token
5. Modify app.nix and flake.nix to build your app and Docker container however you want

GitHub Actions will deploy to staging then production on every push to the main branch.
