Node-RED

Low-code programming for event-driven applications

This chart is not maintained by the Node-RED project and any issues with the chart should be raised here

TL;DR;

helm repo add k8s-at-home https://k8s-at-home.com/charts/
helm install k8s-at-home/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 k8s-at-home/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" \
    k8s-at-home/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 k8s-at-home/node-red

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