本文介绍 kubernetes dashboard 不同于同类博客部署的1.10版本本文部署2.0.0版本

kubenetes v17.3

1.由于镜像地址需要上网国内好像无法下载image

2.这是dashboard 2.0版本地址

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml

kubectl apply -f recommended.yaml

对于image 可查看node节点地址在node节点地址上 docker pull image

在yml文件里 pull对应的版本地址国内缓慢可走docker代理或pull阿里云的镜像后修改tag标签

部署完之后可以查看默认的权限默认权限几乎什么都不能干，根据官方说明需要授权rbac权限

3.授权

创建样本用户

在本指南中，我们将找到如何使用Kubernetes的服务帐户机制创建新用户，授予该用户admin权限以及使用与该用户绑定的承载令牌登录到Dashboard的方法。

重要信息：在继续操作之前，请确保您知道自己在做什么。向仪表板的服务帐户授予管理员特权可能会带来安全风险。

对于每个以下片断ServiceAccount和ClusterRoleBinding，你应该将它们复制到像新的清单文件dashboard-adminuser.yaml，并使用kubectl apply -f dashboard-adminuser.yaml创建它们。

4.创建服务账号

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard

创建ClusterRoleBinding

在大多数情况下，使用kops或kubeadm任何其他流行的工具配置集群后，集群中ClusterRole cluster-admin已经存在该集群。我们可以使用它并仅为ClusterRoleBinding我们创建ServiceAccount。

注意： Kubernetes版本之间apiVersion的ClusterRoleBinding资源可能有所不同。此前Kubernetes v1.8的apiVersion是rbac.authorization.k8s.io/v1beta1。

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

此时可以查看密令

kubectl -n kubernetes-dashboard描述秘密$（ kubectl -n kubernetes-dashboard获取秘密| grep管理员用户| awk ' {print $ 1} '）

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | sls admin-user | ForEach-Object { $_ -Split '\s+' } | Select -First 1)
