node-onbuild

Like official docker node onbuild image, but we're installing npm packages one level above the app folder. Modules will still be found but won't be overridden when mounting the project directory for development.

Breaking change

❗️2016-02-16: Now using CMD [ "node", "app.js" ]`` instead of npm start`, due to npm not forwarding signals such as SIGTERM.

Use in development setup

Dockerfile:

FROM hiotlabs/node-onbuild:latest
RUN npm install -g supervisor

docker-compose.yml:

node:
  build: .
  volumes:
    - .:/usr/src/app
  command: supervisor -e js,json app.js
