kubernetes-dashboard

Kubernetes Dashboard is a general purpose, web-based UI for Kubernetes clusters. It allows users to manage applications running in the cluster and troubleshoot them, as well as manage the cluster itself.

TL;DR

# Add kubernetes-dashboard repository
helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
# Deploy a Helm Release named "kubernetes-dashboard" using the kubernetes-dashboard chart
helm install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard

Introduction

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

Installing the Chart

To install the Chart with the Release name kubernetes-dashboard:

helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
helm install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard

The command deploys kubernetes-dashboard on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the kubernetes-dashboard deployment:

helm delete kubernetes-dashboard

The command removes all the Kubernetes components associated with the chart and deletes the release.

Access control

It is critical for the Kubernetes cluster to correctly setup access control of Kubernetes Dashboard. See this guide for details.

It is highly recommended to use RBAC with minimal privileges needed for Dashboard to run.

Configuration

Please refer to values.yaml for valid values and their defaults.

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

helm install kubernetes-dashboard/kubernetes-dashboard --name kubernetes-dashboard \
  --set=service.externalPort=8080,resources.limits.cpu=200m

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

helm install kubernetes-dashboard/kubernetes-dashboard --name kubernetes-dashboard -f values.yaml

Tip

: You can use the default values.yaml, which is used by default, as reference

Upgrading an existing Release to a new major version

A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an incompatible breaking change needing manual actions.

Upgrade from 5.x.x to 6.x.x

  • Switch PodDisruptionBudget from policy/v1beta1 to policy/v1. Requires kubernetes >= 1.21.0 if podDisruptionBudget.enabled is set to true (false by default).

Upgrade from 4.x.x to 5.x.x

  • Switch Ingress from networking.k8s.io/v1beta1 to networking.k8s.io/v1. Requires kubernetes >= 1.19.0.

Upgrade from 2.x.x to 3.x.x

  • Switch Ingress from extensions/v1beta1 to networking.k8s.io/v1beta1. Requires kubernetes >= 1.14.0.

Upgrade from 1.x.x to 2.x.x

Version 2.0.0 of this chart is the first version hosted in the kubernetes/dashboard.git repository. v1.x.x until 1.10.1 is hosted on https://github.com/helm/charts.

  • This version upgrades to kubernetes-dashboard v2.0.0 along with changes in RBAC management: all secrets are explicitely created and ServiceAccount do not have permission to create any secret. On top of that, it completely removes the clusterAdminRole parameter, being too dangerous. In order to upgrade, please update your configuration to remove clusterAdminRole parameter and uninstall/reinstall the chart.
  • It enables by default values for podAnnotations and securityContext, please disable them if you don't supoprt them
  • It removes enableSkipLogin and enableInsecureLogin parameters. Please use extraArgs instead.
  • It adds a ProtocolHttp parameter, allowing you to switch the backend to plain HTTP and replaces the old enableSkipLogin for the network part.
  • If protocolHttp is not set, it will automatically add to the Ingress, if enabled, annotations to support HTTPS backends for nginx-ingress and GKE Ingresses.
  • It updates all the labels to the new recommended labels, most of them being immutable.
  • dashboardContainerSecurityContext has been renamed to containerSecurityContext.

In order to upgrade, please update your configuration to remove clusterAdminRole parameter and adapt enableSkipLogin, enableInsecureLogin, podAnnotations and securityContext parameters, and uninstall/reinstall the chart.

Version 4.x.x

Starting from version 4.0.0 of this chart, it will only support Helm 3 and remove the support for Helm 2. If you still use Helm 2 you will need first to migrate the deployment to Helm 3 and then you can upgrade your chart.

To do that you can follow the guide

Access

For information about how to access, please read the kubernetes-dashboard manual

Using the dashboard with 'kubectl proxy'

When running 'kubectl proxy', the address localhost:8001/ui automatically expands to:

  • http://localhost:8001/api/v1/namespaces/my-namespace/services/https:kubernetes-dashboard:https/proxy/

For this to reach the dashboard, the name of the service must be 'kubernetes-dashboard', not any other value as set by Helm. You can manually specify this using the value 'fullnameOverride':

fullnameOverride: 'kubernetes-dashboard'
