k8s的dashboard
一、下载v2.0.0-rc4版本
# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-rc4/aio/deploy/recommended.yaml
二、cat 改过的 recommended.yaml文件如下

三、执行
# kubectl apply -f recommended.yaml # kubectl get service -n kubernetes-dashboard | grep dashboard
创建admin-user.yaml文件
#vim admin-user.yaml
--- apiVersion: v1 kind: ServiceAccount metadata: name: admin-user-token namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: admin-user-token roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: admin-user-token namespace: kube-system
说明:上面创建了一个叫admin-user-toen的服务账号,并放在kube-system命名空间下,并将cluster-admin角色绑定到admin-user-toen账户,这样admin-user-toen账户就有了管理员的权限。默认情况下,kubeadm创建集群时已经创建了cluster-admin角色,我们直接绑定即可.
查看token
# kubectl describe secret -n kube-system $(kubectl get secret -n kube-system |grep admin-user-token| awk '{print $1}') Name: admin-user-token-token-9sjhp Namespace: kube-system Labels: <none> Annotations: kubernetes.io/service-account.name: admin-user-token kubernetes.io/service-account.uid: 8b8c26d2-efce-4fc9-b5f3-b35be547a031 Type: kubernetes.io/service-account-token Data ==== ca.crt: 1025 bytes namespace: 11 bytes token: eyJhbGciOiJSUzI1NiIsImtpZCI6ImJNVk5YN2hONzExckdCUFlmZnR0cjlTU3VTYVlOVXRrSVoxQ3hmVHpBLWMifQ.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.qnh6jcMTn1AC4LsFRt2Tmgo4O_mNLd2GpYeM6pF24hV8zXt-o95JFL4mrcZZqVfNmc7knj2Xuen1hq95JzAI9d9-OGHvP9Mla3ydilV-fi8XKZW-1EaxeOnf3pEU0UD013DNs0v_4vXTwEL8h0dHGoMc4e5yYzL30GcMuEpvHM6fjxr0sWhCccDRsBMHEud04XwQTu472JocOz4GtMm6Eob2SgFdDmaI5vDOGBAk-rdgdAEi7Le7xZ741R2OwBNgYE5rOAhdfhDM5RBxyqREz2dOCMWTOUdcn-gZi6HCZJtMbqPwWtQIKNaCz1NQ8rwNpqWxzxFU6pmQWaDtGHJ8Qw
使用火狐浏览器访问 https://192.168.40.137:30002
四、实用命令
1、查看是否有报错(在最后的events)
#kubectl describe svc kubernetes-dashboard -n kubernetes-dashboard
# kubectl describe po kubernetes-dashboard -n kubernetes-dashboard
会提示下载 kubernetesui/dashboard:v2.0.0-rc4 kubernetesui/metrics-scraper:v1.0.1 两个镜像,且所有节点都要下载
2、# kubectl get svc -A
3、# kubectl get deploy -A
4、kubectl delete deploy kubernetes-dashboard -n kubernetes-dashboard (删除坏的服务)
