Kubernetes(K8S)管理，图形界面，Web UI
一、k8s管理界面
这里主要列举以下3个：
官方的kubernetes-dashboardRancherKuboard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
复制
$ kubectl apply -f
https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.3/aio/deploy/recommended.yaml1.2.
step2：如果拉取不了，可以在hosts里配置这个
复制
echo "151.101.108.133 raw.githubusercontent.com" >> /etc/hosts1.
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/dashboardp.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)：复制
registry.cn-hangzhou.aliyuncs.com/kubernetes_ns/dashboard:v2.0.31.
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)
复制
kubectl describe secrets -n kubernetes-dashboard admin-user-token | grep token | awk NR==3{print $2}1.
step5：查看服务端口
复制
[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 11h1.2.3.4.
step6：登录验证

解决办法安装dashboard-adminuser.yaml
复制
kubectl apply -f https://hub.fastgit.org/pythonTaotao/kubernetes/blob/master/dashboard/dashboard-adminuser.yaml1.
