Node-red + docker-compose (updating flows, and dependencies)

michaltaberski · 19 January 2020 18:30

Hey,

I am planning to run node-red using docker (docker-compose in particular). The initial run works and obviously is very simple if you follow this instruction.

However things are getting a bit more complex if a) you are inexperienced with docker-compose b) you need some more configs.

I would like to about advice how to setup following things:

How to set / add dependencies to package.json using nodered/node-red ??
How to load / backup flows.json?

I have setup very initial repo:

github.com

michaltaberski/iot-docker/blob/master/docker-compose.yml

version: "3.7"

# https://nodered.org/docs/getting-started/docker
services:
  node-red:
    image: nodered/node-red:latest
    environment:
      - TZ=Europe/Warsaw
    ports:
      - 1880:1880
    networks:
      - node-red-net
    volumes:
      # it seems it doesn't work - `./volumes/node-red` is permanently empty
      - ./volumes/node-red:/data

networks:
  node-red-net:

Thanks in advance for any advice!

If your Node-RED data directory is bind-mounted at volumes/ and named node-red then set the permissions for the data to be persistent.

chown -R 1000:1000 /volumes/node-red
