How to automatically deploy a Node-RED instance in Docker (including extra nodes)?

I'd like to automatically deploy a Node-RED instance using docker-compose.

The goal is to deploy:

I can't figure out how to deploy palettes on first start, essentially it would be enough to run cd /data; npm install on first start.

Here is my docker-compose.yml file:

version: '2'

services:
  nodered:
    image: nodered/node-red
    user: root:root             # necessary, otherwise we get 'access denied'
    environment:
      TZ: Europe/Amsterdam
    ports:
      - "1880:1880"
    volumes:
      - ./data:/data

After some research I'd like to propose a simple answer to my question.

Pros:

  • Lightweight
  • Works without cloning the official image
  • Doesn't need a rebuild when dependencies change

Cons:

  • I don't like the very last line of my entrypoint.sh (since I had to copy it from the official image)

Modified docker-compose.yml:

version: '2'

services:
  nodered:
    image: nodered/node-red
    user: root:root             # necessary, otherwise we get 'access denied'
    entrypoint: /data/entrypoint.sh
    environment:
      TZ: Europe/Amsterdam
    ports:
      - "1880:1880"
    volumes:
      - ./data:/data

/data/entrypoint.sh file:

#!/bin/sh

DIR=`pwd`

cd /data
npm install

cd "$DIR"
npm start -- --userDir /data

For the sake of simplicity npm install is run during each startup since I figured out that it takes close to nothing (time) and it's very useful if I need to modify package.json on-the-fly. It's very easy to make it run only once by touch-ing a file and then testing for the presence of the file.

You create your own Docker container that extends the nodered/node-red container and include your own package.json that has the extra nodes you want to include in the dependencies section.

Make sure you add your dependencies to the existing package.json file that is included in the base image.

More detailed instuctions can be found in the node-red-docker project on github here
