|
|
|
|
|
* Start an interactive interpreter session with `ghci`:
|
|
|
|
|
|
-```
|
|
|
$ docker run -it --rm haskell:7.8

* Dockerize a [Hackage](http://hackage.haskell.org) app with a Dockerfile inheriting from the base image:
|
|
|
|
|
|
-```
|
|
|
FROM haskell:7.8

RUN cabal update && cabal install MazesOfMonad

ENTRYPOINT ["/root/.cabal/bin/mazesofmonad"]
|
|
|
-```
|

* Iteratively develop then ship a Haskell app with a Dockerfile utilizing the
|
|
|
build cache:

|
|
|
