【Server/Mac】K8S and Dashboard 搭建

本文主要是介绍【Server/Mac】K8S and Dashboard 搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

大概步骤

1. docker 安装
2. k8s dashboard 安装

Docker Install

• 安装 docker edge 会自动安装 k8s
  个人垃圾笔记

K8S dashboard 安装

kubectl apply kubernetes-dashboard.yaml

• 以下是 kubernetes-dashboard.yaml文件的内容
• 遇见的问题：镜像无法下载（docker search kubernetes-dashboard && docker pull ***）

启动 kubectl proxy

端口号处理

1. kubectl get pods --namespace=kube-system

2. 执行：kubectl port-forward kubernetes-dashboard-675cd9bf74-nw67r 8443:8443 --namespace=kube-system
3. 执行：kubectl proxy

安装完成后可以在浏览器中输入以下地址

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login?namespace=default

浏览器结果
