# Node-RED
|
||||
|
||||
Flow-based programming for the Internet of Things
|
||||
|
||||
## TL;DR;
|
||||
|
||||
```console
|
||||
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](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.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------- | ------------------------------- | ---------------------------------------------------------- |
|
||||
| `image.repository` | node-red image | `nodered/node-red-docker` |
|
||||
| `image.tag` | node-red image tag | `0.19.4-v8` |
|
||||
| `image.pullPolicy` | node-red image pull policy | `IfNotPresent` |
|
||||
| `flows` | Default flows configuration | `` |
|
||||
| `nodeOptions` | Node.js runtime arguments | `` |
|
||||
| `timezone` | Default timezone | `` |
|
||||
| `service.type` | Kubernetes service type for the GUI | `ClusterIP` |
|
||||
| `service.port` | Kubernetes port where the GUI is exposed | `1880` |
|
||||
| `service.nodePort` | Kubernetes nodePort where the GUI is exposed | `` |
|
||||
| `service.annotations` | Service annotations for the GUI | `{}` |
|
||||
| `service.labels` | Custom labels | `{}` |
|
||||
| `service.loadBalancerIP` | Loadbalance IP for the GUI | `{}` |
|
||||
| `service.loadBalancerSourceRanges` | List of IP CIDRs allowed access to load balancer (if supported) | None
|
||||
| `service.externalTrafficPolicy` | Set the externalTrafficPolicy in the Service to either Cluster or Local | `Cluster`
|
||||
| `ingress.enabled` | Enables Ingress | `false` |
|
||||
| `ingress.annotations` | Ingress annotations | `{}` |
|
||||
| `ingress.path` | Ingress path | `/` |
|
||||
| `ingress.hosts` | Ingress accepted hostnames | `chart-example.local` |
|
||||
| `ingress.tls` | Ingress TLS configuration | `[]` |
|
||||
| `persistence.enabled` | Use persistent volume to store data | `false` |
|
||||
| `persistence.size` | Size of persistent volume claim | `5Gi` |
|
||||
| `persistence.existingClaim` | Use an existing PVC to persist data | `nil` |
|
||||
| `persistence.storageClass` | Type of persistent volume claim | `-` |
|
||||
| `persistence.accessModes` | Persistence access modes | `ReadWriteOnce` |
|
||||
| `resources` | CPU/Memory resource requests/limits | `{}` |
|
||||
| `nodeSelector` | Node labels for pod assignment | `{}` |
|
||||
| `tolerations` | Toleration labels for pod assignment | `[]` |
|
||||
| `affinity` | Affinity settings for pod assignment | `{}` |
|
||||
|
||||
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.
|
||||
The node-red chart is now an official helm chart: https://github.com/helm/charts/tree/master/stable/node-red
