k8s里面建立一个用户，然后给特定权限，再做rolebinding的过程，给个标准的建立jenkins-admin的用户的过程：
简单来说，三步，ServiceAccout –> Role –> Rolebinding
apiVersion: v1
kind: ServiceAccount
metadata:
name: jenkins-admin
namespace: devops-tools
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: jenkins
namespace: default
labels:
"app.kubernetes.io/name": 'jenkins'
rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["create","delete","get","list","patch","update","watch"]
- apiGroups: [""]
resources: ["pods/exec"]
verbs: ["create","delete","get","list","patch","update","watch"]
- apiGroups: [""]
resources: ["pods/log"]
verbs: ["get","list","watch"]
- apiGroups: [""]
resources: ["secrets"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: jenkins-role-binding
namespace: default
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: Role
name: jenkins
subjects:
- kind: ServiceAccount
name: jenkins-admin
namespace: default
