使用java jdbc套接字工厂从本地docker容器内连接到cloudsql实例

我很难让我的jar从本地docker容器内连接到cloudsql。

如果我在容器外面运行jar：

export GOOGLE_APPLICATION_CREDENTIALS=<path to credentials.json> jar -jar <myjar.jar> 

那么它工作正常。

但是，当我运行这样的docker：

  docker run -d -p MY_SERVER_PORT:MY_SERVER_PORT -p 3306:3306 -v <local path to credentials.json>:<path in container> <image name> 

我在容器日志中得到以下内容：

 Nov 09, 2017 10:37:15 AM org.hibernate.Version logVersion INFO: HHH000412: Hibernate Core {0.0.1} Nov 09, 2017 10:37:15 AM org.hibernate.cfg.Environment <clinit> INFO: HHH000206: hibernate.properties not found Nov 09, 2017 10:37:15 AM org.hibernate.annotations.common.reflection.java.JavaReflectionManager <clinit> INFO: HCANN000001: Hibernate Commons Annotations {5.0.1.Final} Nov 09, 2017 10:37:15 AM org.hibernate.engine.jdbc.connections.internal.DriverManagerConnectionProviderImpl configure WARN: HHH10001002: Using Hibernate built-in connection pool (not for production use!)

有谁知道，如果我不得不打开一些其他的端口，以允许jdbc套接字工厂连接到MySQL服务器？

非常感谢 ：）
