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.

This article is about how to use Helm to deploy kubernetes-dashboard on Kubernetes (K8S).

Prerequisites

Kubernetes (K8S)
Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications.

For more information about installing and using Kubernetes (K8s), see the Kubernetes (K8s) Docs.
Helm
Helm is the best way to find, share, and use software built for Kubernetes.

For more information about installing and using Helm, see the Helm Docs.
