# Ubiqiti Network's Unifi Controller

This is a helm chart for [Ubiqiti Network's](https://www.ubnt.com/) [Unifi Controller](https://unifi-sdn.ubnt.com/)

## TL;DR;

```console
$ helm install stable/unifi
```

## Introduction

This code is adopted from [this original repo](https://github.com/jacobalberty/unifi-docker)

## Installing the Chart

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

```console
$ helm install --name my-release stable/unifi
```
## 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 timezone="America/New York" \
    stable/unifi
```

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/unifi
```

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


## Regarding the services

* `guiService`: represents the main web UI and is what one would normally point the ingress to
* `controllerService`: This is needed in order for the unifi devices to talk to the controller and must be otherwise exposed to the network where the unifi devices run.  If you run this as a NodePort (the default setting), make sure that there is an external loadbalancer that is directing traffic from port 8080 to the NodePort for this service
* `discoveryService`: This needs to be reachable by the unifi devices on the network similar to the controllerService but only during the discovery phase. This is a UDP service
* `stunService`: Also used periodically by the unifi devices to communicate with the controller using UDP.
