一、k8s管理界面
这里主要列举以下3个：
- 官方的kubernetes-dashboard
- Rancher
- Kuboard
二、安装步骤
1、前言
之前部署过dashboard v1.x的版本，后来dashboard升级了，按照之前的部署方式部署后，总是出现无法访问的现象，后面又去github找到最新版的dashboard 部署方式，特此记录。
2、正式安装
step1：安装方式也是类似k8s pod创建，通过kubectl apply方式
$ kubectl apply -f
https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.3/aio/deploy/recommended.yamlstep2：如果拉取不了，可以在hosts里配置这个
echo "151.101.108.133 raw.githubusercontent.com" >> /etc/hosts注意：选择版本时要注意，一定要下载与自己k8s的版本对应dashboard，不然web界面会报404。也就是要看看版本中的"Compatibility"
各版本见官方项目地址：
https://github.com/kubernetes/dashboard github.com/kubernetes/dashboard
step3：优化配置文件(修改相应的镜像配置以免国内无法下载)
我将此服务改为NodePort方式进行部署，方便后续进行测试，镜像地址也修改为阿里云仓库的地址，配置文件地址：
点击直达
github.com/pythonTaotao/kubernetes/tree/master/dashboard
p.s.recommended.yaml文件需要修改2处
- recommended.yaml 中的镜像地址改成(一般官方默认的镜像下载不了)：
registry.cn-hangzhou.aliyuncs.com/kubernetes_ns/dashboard:v2.0.3- recommended.yaml 指定nodeport端口，方便主机上访问
具体如何修改参见此文：

step4：Getting a Bearer Token(登录WEB页面是需要使用)
kubectl describe secrets -n kubernetes-dashboard admin-user-token | grep token | awk 'NR==3{print $2}'
step5：查看服务端口
[root@master ~]# kubectl get svc -n kubernetes-dashboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
dashboard-metrics-scraper ClusterIP 10.100.164.29 <none> 8000/TCP 11h
kubernetes-dashboard NodePort 10.107.131.103 <none> 443:32136/TCP 11hstep6：登录验证
