K8S Dashboard是官方的一个基于WEB的用户界面，专门用来管理K8S集群，并可展示集群的状态。K8S集群安装好后默认没有包含Dashboard，需要额外创建它。如下操作：  
1、下载Dashboard项目清单文件

[root@k8s-master-dev dashboard]# wget https://raw.githubusercontent.com/kubernetes/dashboard/be4f2813b7cc13f682f2af5025d42813c8e7fbd3/aio/deploy/recommended/kubernetes-dashboard.yaml
    [root@k8s-master-dev dashboard]# ls
    kubernetes-dashboard-amd64.tar  kubernetes-dashboard.yaml
    [root@k8s-master-dev dashboard]# docker load < kubernetes-dashboard-amd64.tar

    [root@k8s-master-dev ~]#

2、由于Dashboard项目创建的service类型为ClusterIP，无法提供外部访问。为了让cluster外部用户访问Dashboard，需将service的类型修改为NodePort。如下所示：

[root@k8s-master-dev ~]# kubectl get svc -n kube-system
    NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
    kube-dns               ClusterIP   10.96.0.10       <none>        53/UDP,53/TCP   10d
    kubernetes-dashboard   ClusterIP   10.103.192.236   <none>        443/TCP         15h
    [root@k8s-master-dev ~]#
    [root@k8s-master-dev ~]# kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kube-system
    service/kubernetes-dashboard patched
    [root@k8s-master-dev ~]#
    [root@k8s-master-dev ~]# kubectl get svc -n kube-system
    NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
    kube-dns               ClusterIP   10.96.0.10       <none>        53/UDP,53/TCP   10d
    kubernetes-dashboard   NodePort    10.103.192.236   <none>        443:6774/TCP    15h
    [root@k8s-master-dev ~]#

然后就可以在cluster 外部 访问集群中任何一个node的IP 的 6774端口(https方式访问)。如下图所示：  
![Kebernetes 学习总结(10) Dashboard][Kebernetes _10_ Dashboard]

3、Dashboard 作为一个Pod运行，它自己不做认证。当client 以https的方式访问 dashboard pod时，必须提供一个ServiceAccount ，然后由 Dashboard 这个Pod 将该ServiceAccount 的info发送至 k8s cluser认证。  
所以本例中创建serviceaccount，并绑定至cluster-admin role，如下所示：

[root@k8s-master-dev ~]# kubectl create serviceaccount dashboard-admin -n kube-system
    serviceaccount/dashboard-admin created
    [root@k8s-master-dev ~]# kubectl describe sa dashboard-admin -n kube-system
    Name:                dashboard-admin
    Namespace:           kube-system
    Labels:              <none>
    Annotations:         <none>
    Image pull secrets:  <none>
    Mountable secrets:   dashboard-admin-token-7dx6b
    Tokens:              dashboard-admin-token-7dx6b
    Events:              <none>
    [root@k8s-master-dev ~]# kubectl create clusterrolebinding dashboard-cluster-admin-binding --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
    clusterrolebinding.rbac.authorization.k8s.io/dashboard-cluster-admin-binding created
    [root@k8s-master-dev ~]# kubectl get secret -n kube-system | grep dashboard-admin
    dashboard-admin-token-7dx6b                      kubernetes.io/service-account-token   3         2m
    [root@k8s-master-dev ~]#
    [root@k8s-master-dev ~]# kubectl describe secret dashboard-admin-token-7dx6b -n kube-system
    Name:         dashboard-admin-token-7dx6b
    Namespace:    kube-system
    Labels:       <none>
    Annotations:  kubernetes.io/service-account.name=dashboard-admin

    [root@k8s-master-dev ~]#

使用该serviceAccount的token 即可以访问Dashboard，如下所示：  
![Kebernetes 学习总结(10) Dashboard][Kebernetes _10_ Dashboard 1]

4、由于token过长，使用不方便，为此将配置kubeconfig 以方便用户访问，如下所示：

[root@k8s-master-dev ~]# kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/pki/ca.crt --server="http://192.168.20.79:6443" --embed-certs=true --kubeconfig=/root/cluster-admin.conf
    Cluster "kubernetes" set.
    [root@k8s-master-dev ~]# kubectl config view --kubeconfig=/root/cluster-admin.conf
    apiVersion: v1
    clusters:
    - cluster:

    [root@k8s-master-dev ~]# kubectl config set-credentials dashboard-cluster-admin --token=$DASHBOARD_ADMIN_TOKEN --kubeconfig=/root/cluster-admin.conf
    User "dashboard-cluster-admin" set.

6、如果希望创建 default 名称空间的管理员，而不是整个集群的管理员，可参考如下命令：

kubectl create serviceaccount def-ns-admin -n default
    kubectl create rolebinding def-ns-bingding-admin --clusterrole=admin --serviceaccount=default:def-ns-admin
    kubectl get secret
    kubectl describe secret def-ns-admin-token-nlq7c
    cd /etc/kubernetes/pki/
    kubectl config set-cluster kubernetes --certificate-authority=ca.crt --server="http://192.168.20.79:6443" --embed-certs=true  --kubeconfig=/root/default-ns-admin.conf
    DEF_NS_ADMIN_TOKEN=$(kubectl get secret def-ns-admin-token-nlq7c -o jsonpath={.data.token} | base64 -d)
    kubectl config set-credentials def-ns-admin --token=$DEF_NS_ADMIN_TOKEN --kubeconfig=/root/default-ns-admin.conf
    kubectl config set-context def-ns-admin@kubernetes --cluster=kubernetes --user=def-ns-admin --kubeconfig=/root/default-ns-admin.conf
    kubectl config use-context def-ns-admin@kubernetes --kubeconfig=/root/default-ns-admin.conf
