node-docker-raspberry-zero

Sample Dockerfile and build script for running Node on a Raspberry Pi Zero/1 (armv6)

Purpose

There is an image for Node and armv6 processors but in my experience if you have even a medium sized project it takes a long time to run npm install and I've also had problem with the rpi0 running out of memory. I made this script to easily create the images on a Mac (should work on other OS as well) and then transfer the image to my Pi. That way I can develop my app and the deploy it without having to push to a Docker registry.

Usage

On your local machine

First copy the necessary files to your node-project.

cp .dockerignore \
   Dockerfile.armv6 \
   Dockerfile.armv6.local_npm \
   build_arm.sh \
   PROJECT_DIR

Make sure your Node version is available as an image for armv6 and edit the Dockerfiles accordingly.

Build the armv6 image and save it to a tarball.

./build_arm.sh -n [IMAGE_NAME]

For example ./build_arm.sh -n node-docker-raspberry-zero will generate a file node-docker-raspberry-zero.tar and an image node-docker-raspberry-zero:armv6

If you want to transfer the created tar, pass a hostname and path for scp

./build_arm.sh -d host:/home/pi

If you have NPM installed locally you can fetch node_modules and then copy them into the image (faster). Make sure you local version works with the one in the Dockerfile.

./build_arm.sh -l

On your pi

# Load the transfered tar
docker load -i node-docker-raspberry-zero.tar

docker run  -d --rm --name sample-app \
            -p 5000:5000 \
            node-docker-raspberry-zero:armv6
