如何部署k8s-dashborad-Token登錄方式

如何部署k8s-dashborad-Token登錄方式，很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。

1 部署 dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

 2 修改dashborad以nodeport方式訪問

kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kube-system

3  創建屬于dashboard的 serviceaccount

kubectl create serviceaccount dashboard-admin -n kube-system

查看serviceaccount
kubectl get serviceaccount -n kube-system | grep dashboard-admin

4 創建clusterrolebinding

創建clusterrolebinding 綁定clusterrole 使用serviceaccount認證

kubectl create clusterrolebinding dashboard-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin

我們使用clusterrolebinding 綁定了clusterrole基本上擁有了跟個集群資源的所有權限,如果細化授權需要使用rolebinding綁定clusterrole指定命名空間即可

5 查看生成的token

查看生成的token
# kubectl get secret -n kube-system | grep dashboard-admin* 
dashboard-admin-token-97wz7                       kubernetes.io/service-account-token   3      19h

6 查看令牌

kubectl describe secret dashboard-admin-token-97wz7  -n kube-system
Name:         dashboard-admin-token-97wz7
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboard-admin
              kubernetes.io/service-account.uid: 7e681606-684b-11e9-b76a-000c29980aee

Type:  kubernetes.io/service-account-token

Data
====
ca.crt:     1025 bytes
namespace:  11 bytes
token:      eyJhbGciOiJSUzI1NiIsImtpZCI6IiJ9.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.b67GEYZEK_KZC9decv6KeXGhp9PFCrew9xQTWQ_HkGaerjlEkSX2JE3OVRpPGF84hcbYgfBjvCrAIVNmJmjprMIZCsLeCx3-EXJ93zka4tv1huFaywWDsi4wF3TF9tfYfculHSRuZyAKFenN4UiLPVGK954zUZpM_Rpq3SBpiaw8-HM2CRz0ws8ELpRk5UGRRCAboRB_2hkHbtv36p6qyYbrdSG7gjj-xdw_ncAq6H-Vvdx2j3A6q7cgt9erYvGXwnPdfXePcxPr7BfVwFxm4w2tkb4k-fNxWfQYe6wiJiV907tMpwooX_nx_WQ-dIGtiDEDVJU0sOP85Fy1XI4yxw

6 查看nodeport端口

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,9153/TCP   10d
kubernetes-dashboard   NodePort    10.98.179.47   <none>        443:31559/TCP            19h

7 使用令牌登錄dashboard

https://10.10.25.150:31559

8 如果只給default命名空間的權限呢?

1) 創建一個default的serviceaccount
kubectl create serviceaccount default-admin
2)使用rolebinding綁定clusterrole
kubectl create rolebinding default-admin --clusterrole=admin --serviceaccount=default:default-admin
3)獲取secret 
kubectl get secret | grep default-admin*
NAME                        TYPE                                  DATA   AGE
default-admin-token-476jp   kubernetes.io/service-account-token   3      3m2s
4)查看token值
kubectl describe  secret default-admin-token-476jp

Name:         default-admin-token-476jp
Namespace:    default
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: default-admin
              kubernetes.io/service-account.uid: 609fe45a-68da-11e9-b76a-000c29980aee

Type:  kubernetes.io/service-account-token

Data

5)使用token登錄即可
