Node-RED

Flow-based programming for the Internet of Things

TL;DR;

helm repo add billimek https://billimek.github.io/helm-repo
helm install billimek/node-red

Introduction

This code is adopted from the official node-red docker image which runs the Node-RED application

Installing the Chart

To install the chart with the release name my-release:

helm install --name my-release billimek/node-red

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release --purge

The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install --name my-release \
  --set config.timezone="America/New_York" \
    billimek/node-red

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

helm install --name my-release -f values.yaml billimek/node-red

Read through the values.yaml file. It has several commented out suggested values.
