This example folder contains multiple node-red flow setups, each is isolated with a folder that allows you to run the different examples with the same settings.
You can add customized npm package via npm install or directly modify packages.json. Then rebuild your container image.
Simply to run the following command to build node-red image
./build.sh
To run the container image, use
./run.sh <example-args>
which would mount the current folder (i.e. ./example) onto the containers. We took this as a convenient step as you could change codes with node-red UI and the mounting volume allows the changes to be reflected onto your local file system.
The example-args allows you to specify which example you want to run, for example
./run 0.helloworld
would run the 0.helloworld example.
then you can go to UI, check it out: http://127.0.0.1:1880/
