iHaskell JupyterLab

A Haskell JupyterLab environment in a Docker container.

  1. Current working directory files are accesible in the container.
  2. Matching host user and container user.
  3. JupyterLab extensions; Vim, TOC, Spellchecker, installed and activated.
  4. CodeHappens@ToiletHill.io if I have made an error or if you have questions.

Quickstart

  • Clone IHaskell.
    • git clone https://github.com/gibiansky/IHaskell.git
  • Replace the contents of Dockerfile with 02_Dockerfile.md below.
  • touch jupyter_lab_extensions.sh copy and paste the contents of 03_jupyter_lab_extensions.sh.
  • Build image: 
    docker build --build-arg NB_USER=$(id -un) --build-arg NB_UID=$(id -u) -t heathdrobertson/ihaskell:latest .
  • Run a container: 
    docker run --rm -it -v $(pwd):/home/$(id -un)/codehappens -p=8888:8888 heathdrobertson/ihaskell:latest
  • Copy the produced link to a new browser tab e.g. http://127.0.0.1:8888/?token=cf4cca2dc8c50982f3c90bc843197fc8be1d89c04855fbcb. The token will be different in your console output.

Docker Container Using Nix Shell

Building Haskell Projects With Nix

  • Docker image and container setup.
    • Clone or copy my Dockerfile.
    • Link to my Docker file in github
  • Build the image.
    • docker build --rm -t heathdrobertson/nixshell:latest .
  • Run a container.
    • docker run -it --init --name haskell-mule --network toilethill-net -v $(pwd):/home -p 3000:3000 heathdrobertson/nixshell:latest
  • Building projects With Nix
    • $ nix-shell --pure -p ghc cabal-install --run "cabal init"
  • Auto-generate default.nix file.
    • nix-shell --pure -p cabal2nix --run "cabal2nix ." > default.nix
  • Change file permisions so they can be editied ouside the container.
    • chmod 777 -R ./*

The default.nix file would contain the dependencies and build information extracted from the .cabal file. Note that you have to regenerate default.nix every time you update the .cabal file.
