    For the example above, if everything is correct, the controller will deploy 3 StatefulSet resources and a Headless Service to the cluster. You can access the Seata Server cluster in the cluster through `seata-server-0.seata-server-cluster.default.svc`.

    对于上面这个 CR 的例子而言，如果一切正常的话，controller 将会部署 3 个 StatefulSet 资源和一个 Headless Service 到集群中；在集群中你可以通过 seata-server-0.seata-server-cluster.default.svc 对 Seata Server 集群进行访问。
