# Helm Chart for Harbor

## Introduction

This [Helm](https://github.com/kubernetes/helm) chart installs [Harbor](http://vmware.github.io/harbor/) in a Kubernetes cluster. Welcome to [contribute](CONTRIBUTING.md) to Helm Chart for Harbor.

## Prerequisites

- Kubernetes cluster 1.8+ with Beta APIs enabled
- Kubernetes Ingress Controller is enabled
- Helm CLI 2.8.0+

## Setup a Kubernetes cluster

You can use any tools to setup a K8s cluster.
In this guide, we use [minikube](https://github.com/kubernetes/minikube) 0.25.0 to setup a K8s cluster as the dev/test env.
```bash
# Start minikube
minikube start --vm-driver=none
# Enable Ingress Controller
minikube addons enable ingress
```
## Installing the Chart

First install [Helm CLI](https://github.com/kubernetes/helm#install), then initialize Helm.
```bash
helm init
```
Download Harbor helm chart code.
```bash
git clone https://github.com/vmware/harbor
cd harbor/contrib/helm/harbor
```
Download external dependent charts required by Harbor chart.
```bash
helm dependency update
```
Install the Harbor helm chart with a release name `my-release`:
```bash
helm install --debug --name my-release --set externalDomain=harbor.my.domain,externalPort=443 .
```
**Note:** Make sure `harbor.my.domain` can be resolved to the K8s Ingress Controller IP on the machines where you run docker or access Harbor UI.
You can add `harbor.my.domain` and IP mapping in the DNS server, or in /etc/hosts, or use the FQDN `harbor.<IP>.xip.io`.

The command deploys Harbor on the Kubernetes cluster with the default configuration.
The [configuration](#configuration) section lists the parameters that can be configured in values.yaml or via '--set' flag during installation.

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```bash
helm delete my-release
```

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 Harbor chart and the default values.

## Persistence

You need to create `StorageClass` before you can persist data in persistent volume.

To create a `StorageClass`, set the following value in `values.yaml`:

```yaml
persistence:
  enabled: true

```

Four PVCs will be created automatically:
- adminserver-config
- chartmuseum-data
- database-data
- registry-data

All the created PVCs need to be removed manually after Helm deletes the Chart. 

When running a cluster without persistence, this Chart uses `emptyDir` as the temporary volumes. Data does not survive the termination of a pod.
