# Guide for Node-Red and Kafka-EventHubs Plugin
For tests purposes, this guide will show how you can have a Node-Red running and using stream accessories in a development environment.
## Node-Red

The Node-Red will run in Kubernetes environment. So you must have minikube for tests.

* First of all you must have docker installed. Minikube will need for virtualization.
* Install minikube:

wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
chmod +x minikube-linux-amd64
sudo mv minikube-linux-amd64 /usr/local/bin/minikube

* Install helm: https://helm.sh/docs/intro/install/
* Using this chart helm https://artifacthub.io/packages/helm/k8s-at-home/node-red you can install Node-Red without problems. You must be aware that Node-Red needs a persistent volume, otherwise, you'll lost all your work when you turn off your machine.

#
# IMPORTANT NOTE
#
# This chart inherits from our common library chart. You can check the default values/options here:
# https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common/values.yaml
#

global:
  fullnameOverride: node-red-2

image:
  # -- image repository
  repository: nodered/node-red
  # -- image tag
  tag: 2.1.4
  # -- image pull policy
  pullPolicy: IfNotPresent

# -- environment variables. See [image docs](https://nodered.org/docs/getting-started/docker) for more details.
# @default -- See below
env:
  # -- Set the container timezone
  TZ: UTC
  # -- Node.js runtime arguments
  NODE_OPTIONS:
  # -- Setting to `true` starts Node-RED with the projects feature enabled
  NODE_RED_ENABLE_PROJECTS:
  # -- Setting to `true` starts Node-RED in safe (not running) mode
  NODE_RED_ENABLE_SAFE_MODE:
  # -- Location of the flows configuration file.
  # If you set `FLOWS: ""` then the flow file can be set via the `flowFile` property in the `settings.js` file.
  FLOWS: flows.json

# -- Configures service settings for the chart.
# @default -- See values.yaml
service:
  main:
    ports:
      http:
        port: 1880

ingress:
  # -- Enable and configure ingress settings for the chart under this key.
  # @default -- See values.yaml
  main:
    enabled: true

# -- Configure persistence settings for the chart under this key.
# @default -- See values.yaml
persistence:
  data:
    enabled: true
    mountPath: /data
    accessMode: ReadWriteOnce
    size: 1Gi

* Create a file called values.yaml and paste this content. After that, create the chart:

helm repo add k8s-at-home https://k8s-at-home.com/charts/
helm repo update
helm install node-red k8s-at-home/node-red -f values.yaml

* The last command will help you with configuration, as PVC and Ingresses. Obs.: You can change the field "fullNameOverride" to put your own name.
* Your Node-Red is running somewhere in default namespace
* `kubectl get pods` will show you
* After that, type `kubectl port-forward <pod name> 1880:1880`
* Access your browser on `http://localhost:1880` and you should have access to Node-Red.

## Kafka-EventHubs plugin

**Manage Palette**>>**Install**

If your project is in npm registry, automatically will appear in nodes to install. If not, you will need to pass a tarball (npm pack) of your plugin for Node-Red.

As all plugins in Node-Red, you must install and uninstall using the palette.



If the palette is not working, you can install the plugin directly inside the container using `kubectl exec`, entering in container and applying `npm install <package>`.
