kubernetes 1.9 安装 dashboard

1. 下载文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

2. 修改配置文件

添加type: NodePort，暴露Dashboard服务。注意这里只添加行type: NodePort和nodePort: 30001即可，其他配置不用改，大概位置在末尾的Dashboard Service的spec中，参考如下。

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30001
  selector:
    k8s-app: kubernetes-dashboard

3. 下载镜像 (每个节点)

由于网络原因，配置文件中的k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3镜像无法下载，所以需要进行以下操作提前下载好

docker pull siriuszg/kubernetes-dashboard-amd64:v1.8.3
docker tag siriuszg/kubernetes-dashboard-amd64:v1.8.3 k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3

4. 安装dashboard

kubectl create -f kubernetes-dashboard.yaml

5. 授予Dashboard账户集群管理权限

编写配置文件

vim kubernetes-dashboard-admin.rbac.yaml

---
apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard-admin
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard-admin
  labels:
    k8s-app: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard-admin
  namespace: kube-system

创建账户管理

kubectl create -f kubernetes-dashboard-admin.rbac.yaml

6. 查看dashboard运行的node的IP

$ kubectl -n kube-system get pods -o wide|grep dashboard|awk '{print $7}'
172.16.136.201

这时使用上面获取的IP加上我们配置的端口就可以访问了，例如

172.16.136.201:30001

需要注意的是如果使用了ssl证书需要使用https://172.16.136.201:30001进行访问

7. 登录

页面上有两种登录方式，这时我们使用token的方式登录。token的获取方式如下。

在master节点执行

$kubectl -n kube-system get secret | grep kubernetes-dashboard-admin|awk '{print "secret/"$1}'|xargs kubectl describe -n kube-system|grep token:|awk -F : '{print $2}'|xargs echo

上面获取到的就是token了，复制到登录页就可以登录了
