KubeView

KubeView is a Kubernetes cluster visualiser and graphical explorer.

DISCLAIMER: This is an unofficial chart not supported by KubeView authors.

TL;DR;

$ helm repo add cowboysysop https://cowboysysop.github.io/charts/
$ helm install my-release cowboysysop/kubeview

Introduction

This chart bootstraps a KubeView deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes >= 1.19
• Helm >= 3.1

Installing

Install the chart using:

$ helm repo add cowboysysop https://cowboysysop.github.io/charts/
$ helm install my-release cowboysysop/kubeview

These commands deploy KubeView on the Kubernetes cluster in the default configuration and with the release name my-release. The deployment configuration can be customized by specifying the customization parameters with the helm install command using the --values or --set arguments. Find more information in the configuration section of this document.

Upgrading

Upgrade the chart deployment using:

$ helm upgrade my-release cowboysysop/kubeview

The command upgrades the existing my-release deployment with the most latest release of the chart.

TIP: Use helm repo update to update information on available charts in the chart repositories.

Upgrading to version 3.0.0

Some parameters related to image management have been modified:

• Registry prefix in image.repository parameters is now configured in image.registry.
• Parameter imagePullSecrets has been renamed global.imagePullSecrets.

Upgrading to version 2.0.0

The chart is no more compatible with Helm 2.

Refer to the Helm documentation for more information.

Uninstalling

Uninstall the my-release deployment using:

$ helm uninstall my-release

The command deletes the release named my-release and frees all the kubernetes resources associated with the release.

TIP: Specify the --purge argument to the above command to remove the release from the store and make its name free for later use.

Setting parameters

Specify the parameters you which to customize using the --set argument to the helm install command. For instance,

$ helm install my-release \
    --set nameOverride=my-name cowboysysop/kubeview

The above command sets the nameOverride to my-name.

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

$ helm install my-release \
    --values values.yaml cowboysysop/kubeview

TIP: You can use the default values.yaml.
