k8s带授权时，生成访问k8s api的token

---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: k8s-authorize
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: k8s-authorize
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: k8s-authorize
  namespace: kube-system

上面创建k8s-authorize账户，绑定cluster-admin角色，拥有最高权限,会在该目录下自动创建k8s-authorize的secrets

$ kubectl describe secrets -n kube-system   k8s-authorize-tok

如下图
