運(yùn)維 之前部署過(guò)Dashboard v1.x的版本，后來(lái)Dashboard升級(jí)了，按照之前的部署方式部署后，總是出現(xiàn)無(wú)法訪問(wèn)的現(xiàn)象，后面又去Github找到最新版的Dashboard 部署方式，特此記錄。
站在用戶的角度思考問(wèn)題，與客戶深入溝通，找到張店網(wǎng)站設(shè)計(jì)與張店網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗(yàn)，讓設(shè)計(jì)與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個(gè)性化、用戶體驗(yàn)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(jī)端網(wǎng)站、網(wǎng)站推廣、域名注冊(cè)、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(gè)：
- 官方的kubernetes-dashboard
- Rancher
- Kuboard
二、安裝步驟
1、前言
之前部署過(guò)dashboard v1.x的版本，后來(lái)dashboard升級(jí)了，按照之前的部署方式部署后，總是出現(xiàn)無(wú)法訪問(wèn)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(guò)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里配置這個(gè)
echo "151.101.108.133 raw.githubusercontent.com" >> /etc/hosts注意：選擇版本時(shí)要注意，一定要下載與自己k8s的版本對(duì)應(yīng)dashboard，不然web界面會(huì)報(bào)404。也就是要看看版本中的"Compatibility"
各版本見(jiàn)官方項(xiàng)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(guó)內(nèi)無(wú)法下載)
我將此服務(wù)改為NodePort方式進(jìn)行部署，方便后續(xù)進(jìn)行測(cè)試，鏡像地址也修改為阿里云倉(cāng)庫(kù)的地址，配置文件地址：
點(diǎn)擊直達(dá)
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(rèn)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(jī)上訪問(wèn)
具體如何修改參見(jiàn)此文：
https://www.cnblogs.com/caoxb/p/www.cnblogs.com/caoxb/p/11244285.html
step4：Getting a Bearer Token(登錄WEB頁(yè)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(yàn)證
https://IP:Port
