Node-RED¶

Description¶

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.

Install/Setup¶

This application does not have any specific setup instructions documented. If you need assistance setting up this application please visit our support page.

Common Issues¶

When you first spin up Node-RED, check your container logs docker logs nodered and you might see something like this:

> [email protected] start /usr/src/node-red
> node $NODE_OPTIONS node_modules/node-red/red.js $FLOWS "--userDir" "/data"

fs.js:114
    throw err;
    ^

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

This can be resolved by fixing the permissions on the appdata folder, just run:

sudo chown $USER:$GROUP -R ~/.config/appdata/nodered
