dc_haskell - Docker Compose and Docker files for a haskell container

docker-compose build
docker-compose run haskell bash

cd Projects/my-project
stack install hpack
stack setup
stack build
stack exec my-project

add dependency, for example: directory, it's module System.Directory

package.yaml

dependencies:
- directory

for curated packages that are not part of LTS set, add it in stack.yaml:

extra-deps:
- acme-misiles-0.3

To run scotty-hello:

docker-compose run --rm haskell bash

This will publish the 3000 port. When running not as host mode for its network, will need to do this:

docker-compose run -p 3000 --rm haskell bash

2017 12 08 Started experiementing with Haskell. It's interesting, powerful, mind bending. Its purity is satisfying.
