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.yaml

step2：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：

https://www.cnblogs.com/caoxb/p/www.cnblogs.com/caoxb/p/11244285.html

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            8000/TCP        11h
kubernetes-dashboard        NodePort    10.107.131.103           443:32136/TCP   11h

step6：登录验证

https://IP:Port
