Node-RED Image for Architecture arm64v8

With the contained Dockerfile it is possible to build an image for Node-RED, which runs on an ARM64v8 architecture. This image is for example useable on a Raspberry Pi Mod B.

Features

The following features are included:

• newest Node-RED version
• based on a small Apline OS base image
• username an user id (uid) choosable within build process
• runable on the ARM64v8 architecture

Image Build Process

The image is to build with the following "docker build" command:

docker build --tag <imagename>:<tag> \
--build-arg NODE_RED_USERNAME=<username> \
--build-arg NODE_RED_USERID=<uid> .

Note: With the variables NODE_RED_USERNAME and NODE_RED_USERID the username and the userid (uid) are choosable. With this username and userid will Node-RED starts.

Run the Container

When the image is built the following command the conatiner starts:

docker container run -d \
-p 1880:1880 \
-v <data directory of the host>:<data directory of the host> \
--name <containername> \
<imagename>:<tag>

Run the Container with docker-compose

The following yaml structure must be placed in the docker-compose.yml file:

version: '3.8'
services:
  nodered:
    container_name: <containername>
    build:
      context: .
      dockerfile: <location of the Dockerfile>
      args:
        NODE_RED_USERNAME: <username>
        NODE_RED_USERID: <uid>
    user: <uid>:<gid equal the uid>
    ports:
      - 1880:1880
    volumes:
      - <data directory of the host>:<data directory of the host>
    environment:
      - TZ=Europe/Berlin
    restart: always

With docker-compose build and docker-compose up -d the stack starts.
