Node-RED is a programming tool for wiring together hardware devices, APIs, and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single click.

Running on Torizon​


  • A Toradex Computer on Module with Torizon installed.

Executing the Node-RED Container through the Command-Line​

Getting Node-RED to run on Torizon is very easy, especially because the Node-RED project provides good support and documentation for Docker.

Below is the most basic setup to get started. Execute this command on the SoM:


you can try to use another tag for a newer version, such as latest or any other tag listed on the images's Docker Hub, as long as it is available for your hardware architecture. We use a fixed version to make sure that such a version actually works and further updates do not compromise our examples and documentation.

# docker run -it -p 1880:1880 --name mynodered nodered/node-red:1.0.6-2

Expand the collapsible section below to see sample output. A similar output will be presented:

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

In summary, the Docker image is downloaded and started, and Node-RED is exposed through port 1880.

Alternative: Executing the Node-RED Container through Portainer​

The image TorizonCore with evaluation containers has many different demos. For instructions about how to install Torizon on your board, refer to Toradex Quickstart Guide.

With Portainer opened, explore it by going to the App Templates section in Portainer and click on the Node-RED template.

Available Container Examples in Portainer


On a desktop PC connected to the same network as the Computer on Module, open a web-browser (for example Chrome or Firefox) and use either one of the following URLs:

  • http://<Board's Ethernet IP>:1880


  • http://<SoM name>-<serial number>.local:1880

See the example below for my Apalis iMX8, with Ethernet IP and serial number 0333444555. The zero to the left cannot be disregarded:



  • http://apalis-imx8-0333444555.local:1880

And now you have access to the web-based Node-RED dashboard:
