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 Node-RED is easiest in a Docker container. This is really easy to set up.
docker pull nodered/node-red
Pull the container from the Docker Repository
sudo docker run -d -p 1880:1880 -v /home/ubuntu/docker-nodered/data:/data --name mynodered nodered/node-red
The default port for Node-RED is 1880. Also ensure that the volumes are mapped to a local folder on the host to preserve the configuration.
