dockerize-node-app

CLI tool to generate a Dockerfile for running a NodeJS application, and starting a Docker container from it.

This project was a bit of fun to learn a bit more about combining Docker and Node.js. The features documented below should work but no more features will be added.

Installation

npm install -g dockerize-app

Usage

# creates dockerfile, builds image and runs container
cd /path/to/node/app
dockerize

Dockerfile generation

• Sets node:x.x.x as the base image, where x.x.x is the latest version (using https://semver.io), which satisifies:
• .nvmrc file
• OR engines.node property from package.json
• Adds source code into docker image
• Runs npm install
• Sets start command as npm start or node [entrypoint.js] depending on package.json settings
