三、使用dashboard 一、dashboard介绍 Dashboard是k8s集群管理的一个WebUI它是k8s的一个附加组件所以需要单独来部署我们可以通过图形化的方法创建、删除、修改、查询k8s资源 二、部署安装dashboard组件
Github地址GitHub - kubernetes/dashboard: General-purpose web UI for Kubernetes clusters
参考链接Release v2.5.1 · kubernetes/dashboard · GitHub
可以通过上述地址查询对应k8s的版本来下载对应的dashboard
1.下载dashboard本地文件
[rootk8s1 k8s]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.1/aio/deploy/recommended.yaml
2.修改nodeport的端口范围 以前修改过的不用修改或者你可以不修改而是修改recommended.yaml的文件中的svc资源的端口范围为30000-32767 本次学习我们不修改recommended.yaml文件只修改k8s的svc的nodeport的端口范围 [rootk8s1 k8s]# vim recommended.yaml
# 修改为NodePort
spec:type: NodePortports:- port: 443targetPort: 8443nodePort: 8443selector:k8s-app: kubernetes-dashboard.................................................................[rootk8s1 k8s]# vim /etc/kubernetes/manifests/kube-apiserver.yaml
# 修改NodePort范围
spec:containers:- command:- kube-apiserver#下面这一条加进去就修改完成了自动就会更新稍等一会先会崩溃- --service-node-port-range3000-50000- --advertise-address192.168.1.11
.................................................................3.创建和查看dashboard
[rootk8s1 k8s]# kubectl apply -f recommended.yaml
[rootk8s1 k8s]# kubectl get pods -n kubernetes-dashboard
NAME READY STATUS RESTARTS AGE
dashboard-metrics-scraper-799d786dbf-gjs6w 1/1 Running 0 73s
kubernetes-dashboard-fb8648fd9-2xrkw 1/1 Running 0 73s
4.电脑浏览器访问测试 5.token登录方式登录dashboard
5.1.查看dashboard的token
# 先查看dashboard的sa用户的详细信息
# sa用户有一个token字段这个token字段本质上也是一个secrets资源;[rootk8s1 k8s]# kubectl -n kubernetes-dashboard describe sa kubernetes-dashboard | grep Tokens
Tokens: kubernetes-dashboard-token-qmtlx
5.2.继续查看用户token的secrets资源详细信息
# 继续查看用户token的secrets资源详细信息就可以获取到token的详细编码信息了
[rootk8s1 k8s]# kubectl -n kubernetes-dashboard describe secrets kubernetes-dashboard-token-qmtlx

5.3.复制token编码输入到页面 5.4.解决权限不足的问题
显示没有权限 创建用户绑定角色
[rootk8s231 dashboard]# cat sa-dash.yaml
#创建sa用户叫oslee
apiVersion: v1
kind: ServiceAccount
metadata:labels:k8s-app: kubernetes-dashboard# 创建一个名为oslee的账户name: osleenamespace: kubernetes-dashboard---
#绑定k8s集群中的最大权限的角色与oslee用户

roleRef:apiGroup: rbac.authorization.k8s.io# 既然绑定的是集群角色那么类型也应该为ClusterRole,而不是Role哟~kind: ClusterRole# 关于集群角色可以使用kubectl get clusterrole | grep admin进行过滤哟~name: cluster-admin

serviceaccount/oslee created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-oldboyedu created
使用新用户的token登录dashboard
[rootk8s1 k8s]# kubectl -n kubernetes-dashboard describe sa oslee | grep Tokens
