はじめに

Docker Hub に PureScript が動作するイメージがいくつかアップされていますが、 Node.js v12 かつ spago を使用しているものが見当たらなかったので自分で作成してみました

検証環境

Windows10 Home Edition
VirtualBox 6.1.16
docker-machine.exe version 0.16.1, build cce350d7

# Docker Host OS (CoreOS)
$ uname -a
Linux default 4.14.154-boot2docker #1 SMP Thu Nov 14 19:19:08 UTC 2019 x86_64 GNU/Linux

Docker version 19.03.5, build 633a0ea838
docker-compose version 1.26.0, build d4451659

ディレクトリ構成

purescript フォルダの中に docker-compose.yml と Dockerfile のみ

purescript
|   docker-compose.yml
|   Dockerfile

`docker-compose.yml`

docker-compose.yml

version: "3.7"
services:
  purescript:
    build:
      context: .
      dockerfile: Dockerfile
    image: takaya030/purescript

`Dockerfile`

Dockerfile

FROM node:12
LABEL maintainer "takaya030"

# install purescript
RUN npm install --global --unsafe-perm purescript spago

# add user
RUN userdel node && \
	useradd -m -s /bin/bash pureuser

WORKDIR /home/pureuser
USER pureuser

RUN mkdir tmp && cd tmp && spago init

CMD cd tmp && spago repl

イメージのビルド

$ cd purescript
$ docker-compose build purescript

イメージの確認

$ docker images

動作確認

$ docker-compose run --rm purescript
