1.准备dashboard镜像

运维主机操作

[root@k8s7-200 ~]# docker pull k8scn/kubernetes-dashboard-amd64:v1.10.1
[root@k8s7-200 ~]# docker tag 0c60bcf89900 harbor.od.com/k8s/dashboard:v1.10.1
[root@k8s7-200 ~]# docker push harbor.od.com/k8s/dashboard:v1.10.1

2.准备资源配置清单

[root@k8s7-200 ~]# mkdir -p /data/k8s-yaml/dashboard && cd /data/k8s-yaml/dashboard

1.rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: kubernetes-dashboard
    addonmanager.kubernetes.io/mode: Reconcile
  name: kubernetes-dashboard-admin
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding

    addonmanager.kubernetes.io/mode: Reconcile
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard-admin
  namespace: kube-system

2.deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
spec:
  selector:
    matchLabels:
      k8s-app: kubernetes-dashboard
  template:
    metadata:
      labels:
        k8s-app: kubernetes-dashboard
      annotations:
        scheduler.alpha.kubernetes.io/critical-pod: ''
    spec:
      priorityClassName: system-cluster-critical
      containers:
      - name: kubernetes-dashboard
        image: harbor.od.com/public/dashboard:v1.10.1
        resources:
          limits:
            cpu: 100m
            memory: 300Mi
          requests:
            cpu: 50m
            memory: 100Mi
        ports:
        - containerPort: 8443
          protocol: TCP
        args:
          # PLATFORM-SPECIFIC ARGS HERE
          - --auto-generate-certificates
        volumeMounts:
        - name: tmp-volume
          mountPath: /tmp
        livenessProbe:
          httpGet:
            scheme: HTTPS
            path: /
            port: 8443
          initialDelaySeconds: 30
          timeoutSeconds: 30
      volumes:
      - name: tmp-volume
        emptyDir: {}
      serviceAccountName: kubernetes-dashboard-admin
      tolerations:
      - key: "CriticalAddonsOnly"
        operator: "Exists"

3.service.yaml
apiVersion: v1
kind: Service
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
spec:
  selector:
    k8s-app: kubernetes-dashboard
  ports:
  - port: 443
    targetPort: 8443

4.ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: dashboard.od.com
    http:
      paths:
      - backend:
          serviceName: kubernetes-dashboard
          servicePort: 443

3.依次执行创建

浏览器打开：http://k8s-yaml.od.com/dashboard 检查资源配置清单文件是否正确创建
在任意运算节点应用资源配置清单

[root@k8s7-21.host.com ~]# kubectl apply -f http://k8s-yaml.od.com/dashboard/rbac.yaml
serviceaccount/kubernetes-dashboard-admin created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-admin created
[root@k8s7-21.host.com ~]# kubectl apply -f http://k8s-yaml.od.com/dashboard/deployment.yaml
deployment.apps/kubernetes-dashboard created
[root@k8s7-21.host.com ~]# kubectl apply -f http://k8s-yaml.od.com/dashboard/service.yaml
service/kubernetes-dashboard created
[root@k8s7-21.host.com ~]# kubectl apply -f http://k8s-yaml.od.com/dashboard/ingress.yaml
ingress.extensions/kubernetes-dashboard created

4.解析域名

/var/named/od.com.zone
dashboard	60 IN A 10.4.7.10

5.证书签发

[root@k8s7-200 ~]# cd /opt/certs/
[root@k8s7-200 certs]# (umask 077; openssl genrsa -out dashboard.od.com.key 2048)
[root@k8s7-200 certs]# openssl req -new -key dashboard.od.com.key -out dashboard.od.com.csr -subj "/CN=dashboard.od.com/C=CN/ST=SH/L=Shanghai/O=Datacloak/OU=ops"
[root@k8s7-200 certs]# openssl x509 -req -in dashboard.od.com.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out dashboard.od.com.crt -days 3650
[root@k8s7-200 certs]# ll dashboard.od.com.*
-rw-r--r-- 1 root root 1196 Jan 29 20:52 dashboard.od.com.crt
-rw-r--r-- 1 root root 1005 Jan 29 20:51 dashboard.od.com.csr
-rw------- 1 root root 1675 Jan 29 20:51 dashboard.od.com.key

[root@k8s7-200 certs]# scp dashboard.od.com.key dashboard.od.com.crt k8s7-11:/etc/nginx/certs/  
[root@k8s7-200 certs]# scp dashboard.od.com.key dashboard.od.com.crt k8s7-12:/etc/nginx/certs/

6.配置Nginx

# k8s7-11和k8s7-12都需要操作
[root@k8s7-11 ~]# vim /etc/nginx/conf.d/dashborad.conf
server {
    listen       80;
    server_name  dashboard.od.com;
    rewrite ^(.*)$ https://${server_name}$1 permanent;
}

server {
    listen       443 ssl;
    server_name  dashboard.od.com;

    ssl_certificate "certs/dashboard.od.com.crt";
    ssl_certificate_key "certs/dashboard.od.com.key";
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout  10m;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;

    location / {
        proxy_pass http://default_backend_traefik;
        proxy_set_header Host       $http_host;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
    }
}
[root@k8s7-11 ~]# nginx -t && nginx -s reload

7.测试Token登录

[root@k8s7-21.host.com ~]# kubectl get secret -n kube-system
NAME                                     TYPE                                  DATA   AGE

default-token-6frg9                      kubernetes.io/service-account-token   3      27h
kubernetes-dashboard-admin-token-hqz62   kubernetes.io/service-account-token   3      35m
kubernetes-dashboard-key-holder          Opaque                                2      35m
traefik-ingress-controller-token-zbk57   kubernetes.io/service-account-token   3      114m
