Docker and docker-compose setup for a simple node environment which is setup to support using `yarn` and `yo`

README.md

Run Yarn and Yeoman in a Docker container

Part of my mission to not install any dev tools or dev environments outside of Docker.

Build container

Run docker-compose build.

Get a bash prompt in the container

Run docker-compose run app bash.

Start a new project with yarn

Either:

docker-compose run app bash
yarn init

or:

docker-compose run app yarn init

Adding additonal yeoman generators:

1. Modify Dockerfile to globally include additional generators

   • example: Add RUN yarn globa add generator-exrpess to the end of the Dockerfile

2. Run docker-compose build to rebuild the container

3. Either:

   docker-compose run app bash
   yo express
   

   or:

   docker-compose run app yo express
   

docker-compose.yml

version: "2"
services:
  app:
    build: .
    working_dir: /home/docker/app
    environment:
      - NODE_ENV=production
    volumes:
      - ./:/home/docker/app

Dockerfile

FROM node:9.3

RUN apt-get update
RUN apt-get install sudo

RUN adduser --disabled-password --gecos '' docker
RUN adduser docker sudo
RUN echo '%sudo ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers

USER docker

RUN sudo apt-get update
RUN sudo apt-get install apt-transport-https

RUN sudo curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
RUN sudo echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

RUN sudo apt-get update
RUN sudo apt-get install yarn

ENV PATH=/home/docker/.yarn/bin:$PATH
RUN yarn global add yo

Thanks for pointing that out! I've updated it.
