docker-node-minimal

Tiny Docker - node.js image

This image is based on Michael Hart's (mhart) great mhart/alpine-node Image

Main Purpose

The official Docker node image is about 650MB - which is quite huge. Michael Hart did a really great job to minimize the overhead of an node image down to 50 MB. His image is based on Alpine Linux. I just added a few things, i needed for my base images (git for some npm dependencies) and here is the result:

REPOSITORY                     TAG         SIZE
plusinnovations/node_minimal   latest      66.99 MB
mhart/alpine-node              latest      49.41 MB
node                           latest      652.8 MB

Usage

In the Dockerfile and package.json, you find code to improve the image build process:

Your app

Place your source code in the ./app directory. Starting point is ./app/index.js. If you have a different starting point, just modify it in your package.json ("start" script and "main")

Dockerfile

Please feel free to modify the Dockerfile: here you can enable/disable installation of additional built tools in case that you have native dependencies (line 5 and 6).

Building Your Image

Start building your image with

npm run build

If you want your own image name, just modify the package.json built script (line 9) like so:

  "scripts": {
  	...
  	"build": "docker build -t YOUR_IMAGE_NAME .",
    ...
  },

Running Your New Container

As soon as your image is created, just run it:

docker run plusinnovations/node_minimal
