# Node-RED

Flow-based programming for the Internet of Things

## TL;DR;

```console
helm repo add billimek https://raw.githubusercontent.com/billimek/helm-repo/master
helm install billimek/node-red
```

## Introduction

This code is adopted from the [official node-red docker image](https://hub.docker.com/r/nodered/node-red-docker/) which runs the [Node-RED application](https://nodered.org/)


## Installing the Chart

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

```console
helm install --name my-release billimek/node-red
```
## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
helm delete my-release --purge
```

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

## Configuration

The following tables lists the configurable parameters of the Sentry chart and their default values.

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

```console
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,

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

Read through the [values.yaml](values.yaml) file. It has several commented out suggested values.
