pbrisbin/heroku-haskell-stack repository overview

⁠Heroku Haskell Docker Image

This image is for use with Heroku Docker CLI.

⁠Usage

To build, your project must have

• A stack.yaml
• A cabal file
• A LICENSE

This build stops after stack build --dependencies-only, so your own Dockerfile should COPY in the appropriate source files and RUN stack install itself.

Example:

FROM pbrisbin/heroku-haskell-stack:1.0.2
MAINTAINER Pat Brisbin <[email protected]>

COPY src /app/user/src
COPY app /app/user/app
RUN stack install

Executables will be installed in /app/user/bin, which is added to $PATH, in case you want to set one as CMD.

To deploy, your project must have

• A Procfile:

  web: ./bin/foo
  

  Copy

• An app.json:

  {
    "name": "foo",
    "description": "Doesn't matter"
  }
  

  Copy

• A docker-compose.yml

  web:
    build: .
  

  Copy

Then run heroku docker:release
