创建连接K8S的凭据

查看需要使用到的命名空间

[root@k8s ~]# kubectl get ns |grep arts-system
arts-system       Active   16d

创建service accounts

[root@k8s ~]# kubectl create sa jenkins-k8s -n arts-system
serviceaccount/jenkins-k8s created
[root@k8s ~]# kubectl get sa -n arts-system |grep jenkins
jenkins-k8s   1         14s

对jenkins做cluster-admin绑定

[root@k8s ~]# kubectl create clusterrolebinding jenkins-k8s-role-binding --clusterrole cluster-admin --serviceaccount=arts-system:jenkins-k8s -n arts-system
clusterrolebinding.rbac.authorization.k8s.io/jenkins-k8s-role-binding created
[root@k8s ~]# kubectl get clusterrolebinding -n arts-system
NAME                       AGE
jenkins-k8s-role-binding   29s
system:coredns             3y264d

查看arts-system命名空间中的sa和secret

[root@k8s ~]# kubectl get sa,secret -n arts-system
NAME                         SECRETS   AGE
serviceaccount/default       1         16d
serviceaccount/jenkins-k8s   1         3m30s

NAME                             TYPE                                  DATA   AGE
secret/default-token-scbjb       kubernetes.io/service-account-token   3      16d
secret/jenkins-k8s-token-qjr6p   kubernetes.io/service-account-token   3      3m30s

提取token

[root@k8s ~]# kubectl describe secrets jenkins-k8s-token-qjr6p -n arts-system
Name:         jenkins-k8s-token-qjr6p
Namespace:    arts-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: jenkins-k8s
              kubernetes.io/service-account.uid: e7d1633d-3419-4a95-b8e8-e4f1956989e8
