1.进入/kubernetes/cluster/addons/dashboard目录
a.修改dashboard-controller.yaml为国内镜像或者自己私服的镜像

<         image: siriuszg/kubernetes-dashboard-amd64:v1.8.3
---
>         image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3

b.修改dashboard-service.yaml加入type: NodePort

spec:
  type: NodePort
  selector:
    k8s-app: kubernetes-dashboard
  ports:
  - port: 443
    targetPort: 8443

2.执行定义的文件

kubectl create -f  .

3.查看分配的NodePort

kubectl get deployment kubernetes-dashboard  -n kube-system

输出

NAME                   DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
kubernetes-dashboard   1         1         1         1         37s

输出

kubectl --namespace kube-system get pods -o wide

NAME                                    READY     STATUS    RESTARTS   AGE       IP            NODE         NOMINATED NODE
coredns-5f94b495b5-4m7gl                1/1       Running   0          19h       172.30.97.3   kube-node3   <none>
coredns-5f94b495b5-hjjvp                1/1       Running   0          19h       172.30.19.3   kube-node2   <none>
kubernetes-dashboard-55746544c9-tkqts   1/1       Running   0          53s       172.30.31.4   kube-node1   <none>

kubectl get services kubernetes-dashboard -n kube-system

输出

NAME                   TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
kubernetes-dashboard   NodePort   10.254.158.241   <none>        443:8601/TCP   1m

4.获取集群信息

kubectl cluster-info

输出

Kubernetes master is running at https://172.17.13.204:6443
CoreDNS is running at https://172.17.13.204:6443/api/v1/namespaces/kube-system/services/coredns:dns/proxy
kubernetes-dashboard is running at https://172.17.13.204:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

5.访问
https://123.56.41.163:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy
会出现没有证书及401 Forbiden，需根据以下步骤 并将ca.pen和生成的admin.pfx下载到本地导入并重启浏览器
https://github.com/opsnull/follow-me-install-kubernetes-cluster/blob/master/A.浏览器访问kube-apiserver安全端口.md
生成证书openssl pkcs12 -export -out admin.pfx -inkey admin-key.pem -in admin.pem -certfile ca.pem
记住生成证书时的密码，把admin.pfx及ca.pem导入到本地

重启浏览器后访问
https://123.56.41.163:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
根据提示确认admin证书并输入密码，还会提示输入本机用户名及密码

可以使用token或者Kubeconfig两种方式登录，建议使用后者
1.创建登录 token

kubectl create sa dashboard-admin -n kube-system
kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
ADMIN_SECRET=$(kubectl get secrets -n kube-system | grep dashboard-admin | awk '{print $1}')
DASHBOARD_LOGIN_TOKEN=$(kubectl describe secret -n kube-system ${ADMIN_SECRET} | grep -E '^token' | awk '{print $2}')
echo ${DASHBOARD_LOGIN_TOKEN}

可以使用token登录
2.根据上述生成的 token 生成 KubeConfig 文件

# 设置集群参数
kubectl config set-cluster kubernetes \
  --certificate-authority=/etc/kubernetes/cert/ca.pem \
  --embed-certs=true \
  --server=${KUBE_APISERVER} \
  --kubeconfig=dashboard.kubeconfig

# 设置客户端认证参数，使用上面创建的 Token
kubectl config set-credentials dashboard_user \
  --token=${DASHBOARD_LOGIN_TOKEN} \
  --kubeconfig=dashboard.kubeconfig

# 设置上下文参数
kubectl config set-context default \
  --cluster=kubernetes \
  --user=dashboard_user \
  --kubeconfig=dashboard.kubeconfig

# 设置默认上下文
kubectl config use-context default --kubeconfig=dashboard.kubeconfig

把生成的dashboard.kubeconfig拷贝到本地，登录仪表板时使用
