# Node-RED | ||
|
||
Flow-based programming for the Internet of Things | ||
|
||
## TL;DR; | ||
|
||
```console | ||
helm install stable/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 stable/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 | `UTC` | | ||
| `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" \ | ||
stable/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 stable/node-red | ||
``` | ||
|
||
Read through the [values.yaml](values.yaml) file. It has several commented out suggested values. |
