While some open-source solutions are read-only, the dashboard allows you to deploy, troubleshoot, and actively manage system components. Kubernetes provides a dashboard for users to interact with Kubernetes and perform some tasks. What version of Kubernetes Dashboard (1.6 or 1.7) is this Yaml file? It uses Kubernetes manifests for the setup. To access the dashboard with full administrative permission, create a YAML file named dashboard-admin.yaml. This YAML file by itself isn't enough to use the Operator, but the Operator installation will come later in this tutorial. As such, it is a crucial piece of the Kubernetes puzzle since it allows DevOps and Kubernetes administrators to observe and control the monitoring and operational elements of their Kubernetes clusters. To do this from dashboard by uploading the yaml file - delete your existing deployment and upload the modified file. Kubernator is a capable YAML editor linked directly into a Kubernetes cluster. Deploy the latest Kubernetes dashboard. Apply the manifest file ingress-dashboard.yaml: kubectl apply -f ingress-dashboard.yaml. Note that default kubernetes-dashboard service is created using ClusterIP type - so you are able right now to access it. In contrast to high-level Kubernetes Dashboard, Kubernator provides low-level control and clean view on all objects in a cluster with the ability to create new ones, edit and resolve conflicts. 在阅读本文前你需要： 有一个可以操作的 kubernetes 集群 熟悉 kubectl 命令，比如 get，lo.

Getting Started IMPORTANT: Read the Access Control guide before performing any further steps. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized application, and manage the cluster resources. 3. The Kubernetes Dashboard is essentially a web UI for managing the Kubernetes cluster that it is deployed on. First, open your favorite SSH client and connect to your Kubernetes master node. YAML is a human-readable text-based format that let's you easily specify configuration-type information by using a combination of maps of name-value pairs and lists of items (and nested versions of each). Before installing Kubernetes, you need to install the command line (CLI) tool called kubectl (pronounced: cube-cuttle). View the manifest file or files that you downloaded and note the name of the image. The dashboard can display all workloads running in the cluster. A Kubernetes dashboard is a web-based Kubernetes user interface which is used to deploy containerized applications to a Kubernetes cluster, troubleshoot the applications, and manage the cluster itself along with its attendant resources.
