Snap haskell web framework set up to build inside docker using stack

# What's going on here?!

Here we have a lovely little project which hopefully nicely joins together;

• Snap, a web framework for Haskell
• Persistent, for typed data serialization with multiple backends (although just postgres here)
• Stack, a build tool for Haskell
• Docker, which is awesome

We have two docker files, snap.dev and snap.prod.

• snap.dev

  • This is the toolchain for building our application. To run a local dev server which rebuilds every time you make a change, just run docker-compose build && docker-compose up

• snap.prod

  • This is the base for our production image. Once snap.dev has built our app, it is copied into this image, which uses the application as its entrypoint. To make a full production image, simply run make. Warning - this takes a while
