dashboard
图形化界面，k8s官方提供的，也可以使用第三方的插件
安装dashboard
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml# 会创建一些资源
[root@master dashboard]# kubectl get pod -n kubernetes-dashboard
NAME READY STATUS RESTARTS AGE
dashboard-metrics-scraper-6f669b9c9b-rggkc 1/1 Running 0 24s
kubernetes-dashboard-758765f476-t2wk9 1/1 Running 0 24s修改svc类型,默认是clusterip改成nodeport
[root@master dashboard]# kubectl get svc -n kubernetes-dashboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
dashboard-metrics-scraper ClusterIP 10.109.89.187 <none> 8000/TCP 108s
kubernetes-dashboard ClusterIP 10.100.202.80 <none> 443/TCP 108s# 将clusterIP改成NodePort
[root@master dashboard]# kubectl edit svc -n kubernetes-dashboard kubernetes-dashboard
service/kubernetes-dashboard edited[root@master dashboard]# kubectl get svc -n kubernetes-dashboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
dashboard-metrics-scraper ClusterIP 10.109.89.187 <none> 8000/TCP 2m26s
kubernetes-dashboard NodePort 10.100.202.80 <none> 443:32154/TCP 2m26s访问
可以使用kubeconfig文件登录，将admin.conf上传即可
或者使用token，是sa中的token,也就是sa绑定的secret中的token
创建一个sa
kubectl create sa sa-dashboard -n kube-system --dry-run=client -o yaml > sa-dashboard.yml创建一个集群角色绑定
将admin角色绑定到sa
kubectl create clusterrolebinding dashboard-role --clusterrole=admin --serviceaccount kube-system:sa-dashboard -n kube-system --dry-run=client -o yaml > dashboard-rolebinding.yml
查看secret中的token
我这个是1.23的，创建sa会自动的创建一个secret,如果是高版本的话，还需要手动的创建secret关联sa账户才可以
[root@master dashboard]# kubectl describe secrets -n kube-system sa-dashboard-token-5b84z
helm
helm就是一个自动化部署一些资源
自定义一些配置
1、安装helm
、下载tar包
[root@master helm]# wget https://get.helm.sh/helm-v3.14.1-linux-amd64.tar.gz[root@master helm]# tar -xf helm-v3.14.1-linux-amd64.tar.gz
[root@master linux-amd64]# mv helm /usr/local/bin/、配置helm补全
[root@master linux-amd64]# echo "source <(helm completion bash)" >> /etc/profilebash
2、配置helm源
就是这个源有很多的模版，自定义一些配置，自动化部署
# 当前没有添加源
[root@master ~]# helm repo list
Error: no repositories to show[root@master ~]# helm repo add microsoft http://mirror.azure.cn/kubernetes/charts
"microsoft" has been added to your repositories
[root@master ~]# helm repo list
NAME URL
microsoft http://mirror.azure.cn/kubernetes/charts3、使用helm
search
[root@master ~]# helm search repo mysql

[root@master mysql]# ls
Chart.yaml README.md templates values.yaml执行安装
# 修改values.yml这个文件，即可
[root@master mysql]# ls
Chart.yaml README.md templates values.yaml# templates目录下面有很多的yml文件修改自定义一些配置
# 将pv关闭
persistence:enabled: false# 设置root密码

# db起的名字，mysql为目录
[root@master ~]# helm install db mysql# 自动的部署了一个pod
[root@master rbac]# kubectl get pod
