站在用戶的角度思考問題，與客戶深入溝通，找到張店網(wǎng)站設(shè)計與張店網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設(shè)計與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：成都做網(wǎng)站、網(wǎng)站建設(shè)、企業(yè)官網(wǎng)、英文網(wǎng)站、手機端網(wǎng)站、網(wǎng)站推廣、域名注冊、網(wǎng)絡(luò)空間、企業(yè)郵箱。業(yè)務(wù)覆蓋張店地區(qū)。

一、k8s管理界面

這里主要列舉以下3個：

• 官方的kubernetes-dashboard
• Rancher
• Kuboard

二、安裝步驟

1、前言

之前部署過dashboard v1.x的版本，后來dashboard升級了，按照之前的部署方式部署后，總是出現(xiàn)無法訪問的現(xiàn)象，后面又去github找到最新版的dashboard 部署方式，特此記錄。

2、正式安裝

step1：安裝方式也是類似k8s pod創(chuàng)建，通過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里配置這個

echo "151.101.108.133 raw.githubusercontent.com" >> /etc/hosts

注意：選擇版本時要注意，一定要下載與自己k8s的版本對應(yīng)dashboard，不然web界面會報404。也就是要看看版本中的"Compatibility"

各版本見官方項目地址：

https://github.com/kubernetes/dashboard github.com/kubernetes/dashboard

step3：優(yōu)化配置文件(修改相應(yīng)的鏡像配置以免國內(nèi)無法下載)

我將此服務(wù)改為NodePort方式進行部署，方便后續(xù)進行測試，鏡像地址也修改為阿里云倉庫的地址，配置文件地址：

github.com/pythonTaotao/kubernetes/tree/master/dashboard

p.s.recommended.yaml文件需要修改2處

• recommended.yaml 中的鏡像地址改成(一般官方默認的鏡像下載不了)：

registry.cn-hangzhou.aliyuncs.com/kubernetes_ns/dashboard:v2.0.3

• recommended.yaml 指定nodeport端口，方便主機上訪問

具體如何修改參見此文：

step4：Getting a Bearer Token(登錄WEB頁面是需要使用)

kubectl describe secrets -n kubernetes-dashboard admin-user-token  | grep token | awk 'NR==3{print $2}'

step5：查看服務(wù)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：登錄驗證

https://IP:Port

解決辦法安裝dashboard-adminuser.yaml

kubectl apply -f https://hub.fastgit.org/pythonTaotao/kubernetes/blob/master/dashboard/dashboard-adminuser.yaml
