This image is part of the resin.io base image series for IoT devices. The image is optimized for use with resin.io and resinOS, but can be used in any Docker environment running on the appropriate architecture.
What is resin.io?
Resin.io is the simplest way to build, deploy, and manage containers on a fleet of connected devices. Resin.io brings a modern developer workflow to the Internet of Things, enabling rapid innovation at every stage and scale of your project.

resin-io-library/official-images GitHub repo.
What is Node.js?
Node.js applications are designed to maximize throughput and efficiency, using non-blocking I/O and asynchronous events. Node.js applications run single-threaded, although Node.js uses multiple threads for file and network events. Node.js is commonly used for real-time applications due to its asynchronous nature.
How to use this image
OpenRC can be enabled by adding
ENV INITSYSTEM on to your Dockerfile below the
FROM <Docker image> line. This will trigger OpenRC init system on the Docker image.
Dockerfile in your Node.js app project
FROM resin/am571x-evm-alpine-node:onbuild # Enable OpenRC ENV INITSYSTEM on # replace this with your application's default port EXPOSE 8888
You can then build and run the Docker image:
docker build -t my-nodejs-app . docker run -it --rm --name my-running-app my-nodejs-app
Run a single Node.js script
For many simple, single file projects, you may find it inconvenient to write a complete
Dockerfile. In such cases, you can run a Node.js script by using the Node.js Docker image directly:
docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp resin/am571x-evm-alpine-node:latest node your-daemon-or-script.js
