Helm Chart for Harbor

Introduction

This Helm chart installs Harbor in a Kubernetes cluster. Currently this chart supports Harbor v1.4.0 release.

Prerequisites

• Kubernetes cluster 1.8+ with Beta APIs enabled
• Kubernetes Ingress Controller is enabled
• kubectl CLI 1.8+
• 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 to setup a K8s cluster as the dev/test env.

# Start minikube
minikube start --vm-driver=none
# Enable Ingress Controller
minikube addons enable ingress

Installing the Chart

First install Helm CLI, then initialize Helm.

helm init

Download Harbor helm chart code.

git clone https://github.com/vmware/harbor
cd contrib/helm/harbor

Download external dependent charts required by Harbor chart.

helm dependency update

Secure Registry Mode

By default this chart will generate a root CA and SSL certificate for your Harbor. You can also use your own CA signed certificate:

open values.yaml, set the value of 'externalDomain' to your Harbor FQDN, and set value of 'tlsCrt', 'tlsKey', 'caCrt'. The common name of the certificate must match your Harbor FQDN.

Install the Harbor helm chart with a release name my-release:

helm install . --debug --name my-release --set externalDomain=harbor.my.domain

Make sure harbor.my.domain resolves 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.

Follow the NOTES section in the command output to get Harbor admin password and add Harbor root CA into docker trusted certificates.

The command deploys Harbor on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured in values.yaml or via '--set' params during installation.

Tip

: List all releases using helm list

Insecure Registry Mode

If setting Harbor Registry as insecure-registries for docker, you don't need to generate Root CA and SSL certificate for the Harbor ingress controller.

Install the Harbor helm chart with a release name my-release:

helm install . --debug --name my-release --set externalDomain=harbor.my.domain,insecureRegistry=true

Make sure harbor.my.domain resolves 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.

Then add "insecure-registries": ["harbor.my.domain"] in the docker daemon config file and restart docker service.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

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.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example:

helm install --name my-release --set mysql.pass=baconeggs .

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install --name my-release -f /path/to/values.yaml .

Tip

: You can use the default values.yaml

Persistence

Harbor stores the data and configurations in emptyDir volumes. You can change the values.yaml to enable persistence and use a PersistentVolumeClaim instead.

"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."
