Kubernetes Dashboard部署

1. 准备安装kubernetes dashboard的yaml文件

[root@master ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml

 

2. 创建 serviceaccount

[root@master ~]# cat dashboard-sa.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: dashboard-admin
  namespace: kubernetes-dashboard

3. 创建clusterrolebinding为dashboard sa授权集群权限cluster-admin

[root@master ~]# cat dashboard-clusterrolebinding.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: dashboard-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: dashboard-admin
  namespace: kubernetes-dashboard

4. 启动服务

[root@master ~]# kubectl apply -f  recommended.yaml -f dashboard-sa.yaml -f dashboard-clusterrolebinding.yaml

5. 访问

修改kubernetes-dashboard namespace中的svc kubernetes-dashboard 的spec.type为NodePort，便于我们从集群外使用浏览器访问dashboard

• 方法1. 修改 recommended.yaml文件

service段配置更改如下：(nodePort: 30001可以省略，缺省则为随机端口，服务启动后使用kubectl get svc -n kubernetes-dashboard查看)

          方法2. 热更新打补丁的方式修改svc

kubectl -n kubernetes-dashboard patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}'

谷歌浏览器可能出现问题，使用Firefox浏览器添加例外可能可以跳过证书问题

Firefox浏览器查看 

获取验证token

[root@master ~]# kubectl describe secret -n kubernetes-dashboard $(kubectl get secret -n kubernetes-dashboard | grep dashboard-admin | awk '{print $1}')

 

 

 

 you can install Dashboard using Helm as described at https://hub.helm.sh/charts/k8s-dashboard/kubernetes-dashboard.
