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;
    ^

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

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