Installation

Install with helm

If you have a kubernetes cluster, helm is the recommended installation method.

The following tutorial will guide you to install Karpor using Helm, which will install the chart with the release name karpor-release in namespace karpor.

Prerequisites

• Helm v3+
• A Kubernetes Cluster (The simplest way is to deploy a kubernetes cluster locally using kind or minikube)

Remote Installation

First, add the karpor chart repo to your local repository.

helm repo add kusionstack https://kusionstack.github.io/charts
helm repo update

Then you can use the following command to install the latest version of Karpor.

helm install karpor-release kusionstack/karpor

Note that installing this chart directly means it will use the default template values for Karpor.

You may have to set your specific configurations if it is deployed into a production cluster, or you want to customize the chart configuration, such as resources, replicas, port etc.

All configurable parameters of the Karpor chart are detailed here.

helm install karpor-release kusionstack/karpor --set server.replicas=3 --set syncer.port=7654

Search all available versions

You can use the following command to view all installable chart versions.

helm repo update
helm search repo kusionstack/karpor --versions

Upgrade specified version

You can specify the version to be upgraded through the --version.

# Upgrade to the latest version.
helm upgrade karpor-release kusionstack/karpor

# Upgrade to the specified version.
helm upgrade karpor-release kusionstack/karpor --version 1.2.3

Local Installation

If you have problem connecting to https://kusionstack.github.io/charts/ in production, you may need to manually download the chart from here and use it to install or upgrade locally.

git clone https://github.com/KusionStack/charts.git
helm install karpor-release charts/karpor
helm upgrade karpor-release charts/karpor

Uninstall

To uninstall/delete the karpor-release helm release in namespace karpor:

helm uninstall karpor-release

Image Registry Proxy for China

If you are in China and have problem to pull image from official DockerHub, you can use the registry proxy:

helm install karpor-release kusionstack/karpor --set registryProxy=docker.m.daocloud.io

NOTE: The above is just an example, you can replace the value of registryProxy as needed.
