Minimal example of deploying a Nix'd Haskell App to Heroku using the container registry

Haskell on Heroku

Development

Ensure you have Nix installed and run:

$ nix-shell -A env --command "runhaskell Main.hs"

You should now have a pretty great web site running. Point a web browser at http://localhost:8000/hello/world to see it.

Deployment

1. Create a new Heroku App.

2. Ensure you have Docker installed and running.

3. Log into the heroku cli and container registry.

$ nix-shell -p heroku
$ heroku login
$ heroku container:login

4. Run the deploy script with your Heroku App name.

$ ./deploy infinite-anchorage-09330

5. Open a browser and see it in action.
