-# Node-RED

-Low-code programming for event-driven applications
+This is a helm chart for [Node-Red](https://nodered.org/).
 
 **This chart is not maintained by the Node-RED project and any issues with the chart should be raised [here](https://github.com/k8s-at-home/charts/issues/new)**
 
 ## TL;DR;
 
 ```shell
-helm repo add k8s-at-home https://k8s-at-home.com/charts/
+$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
-helm install k8s-at-home/node-red
+$ helm install k8s-at-home/node-red
 ```
 
-## Introduction
-
-This code is adopted from the [official node-red docker image](https://hub.docker.com/r/nodered/node-red/) which runs the [Node-RED application](https://nodered.org/)
-
 ## Installing the Chart
 
 To install the chart with the release name `my-release`:
 
-```shell
+```console
 helm install --name my-release k8s-at-home/node-red
 ```
+
 ## Uninstalling the Chart
 
 To uninstall/delete the `my-release` deployment:
 
-```shell
+```console
 helm delete my-release --purge
 ```
 
 The command removes all the Kubernetes components associated with the chart and deletes the release.
 
 ## Configuration
-
+Read through the charts [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/node-red/values.yaml)
-The following tables lists the configurable parameters of the Node-RED chart and their default values.
+file. It has several commented out suggested values.
-
+Additionally you can take a look at the common library [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/common/values.yaml) for more (advanced) configuration options.

+---
+**NOTE**
+
+If you get
+```console
+Error: rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: ...`
+```
+it may be because you uninstalled the chart with `skipuninstall` enabled, you need to manually delete the pvc or use `existingClaim`.

+
+## Upgrading an existing Release to a new major version
+
+A major chart version change (like 4.0.1 -> 5.0.0) indicates that there is an incompatible breaking change potentially needing manual actions.
+
+### Upgrading from 3.x.x to 4.x.x
+
+Due to migrating to a centralized common library some values in `values.yaml` have changed.
+
+Examples:
+
+* `service.port` has been moved to `service.port.port`.
+* `persistence.type` has been moved to `controllerType`.
+
+Refer to the library values.yaml for more configuration options.
