部署Dashboard
这里部署dashboard v1.10.1版本。
由于yaml配置文件中指定镜像从google拉取，先下载yaml文件到本地，修改配置从阿里云仓库拉取镜像。
$ wget https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
修改yaml配置文件image部分，指定镜像从阿里云镜像仓库拉取：
[centos@k8s-master ~]$ vim kubernetes-dashboard.yaml
…
containers:
- name: kubernetes-dashboard
#image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
image: registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-amd64:v1.10.1
ports:
然后执行以下命令部署dashboard服务：
[centos@k8s-master ~]$ kubectl create -f kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created
[centos@k8s-master ~]$
查看Pod 的状态为running说明dashboard已经部署成功：
[centos@k8s-master ~]$ kubectl get pod --namespace=kube-system -o wide | grep dashboard
kubernetes-dashboard-847f8cb7b8-wrm4l 1/1 Running 0 19m 10.244.2.5 k8s-node2
[centos@k8s-master ~]$
Dashboard 会在 kube-system namespace 中创建自己的 Deployment 和 Service：
[centos@k8s-master ~]$ kubectl get deployment kubernetes-dashboard --namespace=kube-system
NAME READY UP-TO-DATE AVAILABLE AGE
kubernetes-dashboard 1/1 1 1 21m
[centos@k8s-master ~]$
[centos@k8s-master ~]$ kubectl get service kubernetes-dashboard --namespace=kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes-dashboard ClusterIP 10.104.254.251 443/TCP 21m
[centos@k8s-master ~]$

访问dashboard
NodePort方式访问
[centos@k8s-master ~]$ vim kubernetes-dashboard.yaml
…

------------------- Dashboard Service -------------------

kind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
spec:
type: NodePort #增加type: NodePort
ports:
- port: 443
targetPort: 8443
nodePort: 31620 #增加nodePort: 31620
selector:
k8s-app: kubernetes-dashboard
重新应用yaml文件
kubectl apply -f kubernetes-dashboard.yaml
查看service，TYPE类型已经变为NodePort，端口为31620
[centos@k8s-master ~]$ kubectl get service -n kube-system | grep dashboard
kubernetes-dashboard NodePort 10.107.160.197 443:31620/TCP 32m
[centos@k8s-master ~]$
通过浏览器访问：https://192.168.3.115:31620/， 登录界面如下：

创建登录用户
创建dashboard-adminuser.yaml：
[centos@k8s-master ~]$ vim dashboard-adminuser.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kube-system

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: kube-system

执行yaml文件：
kubectl create -f dashboard-adminuser.yaml
查看admin-user账户的token
[centos@k8s-master ~]$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk ‘{print $1}’)
Name: admin-user-token-jtlbp
Namespace: kube-system
Labels:
Annotations: kubernetes.io/service-account.name: admin-user
kubernetes.io/service-account.uid: a345b4d5-1006-11e9-b90d-000c291c25f3

Type: kubernetes.io/service-account-token
