因为运行在容器中的 TDengine 服务端使用容器的 hostname 建立连接，使用 taos shell 或者各种连接器（例如 JDBC-JNI）从容器外访问容器内的 TDengine 比较复杂，所以上述方式是访问容器中 TDengine 服务的最简单的方法，适用于一些简单场景。如果在一些复杂场景下想要从容器化使用 taos shell 或者各种连接器访问容器中的 TDengine 服务，请参考下一节。 因为运行在容器中的 TDengine 服务端使用容器的 hostname 建立连接，使用 taos shell 或者各种连接器（例如 JDBC-JNI）从容器外访问容器内的 TDengine 比较复杂，所以上述方式是访问容器中 TDengine 服务的最简单的方法，适用于一些简单场景。如果在一些复杂场景下想要从容器化使用 taos shell 或者各种连接器访问容器中的 TDengine 服务，请参考下一节。

从上面的输出可以看到有两个 dnode， 和两个 taosAdapter，以及一个 nginx 反向代理服务。 从上面的输出可以看到有两个 dnode， 和四个 taosAdapter，以及一个 nginx 反向代理服务。
接下来，我们可以减少 taosAdapter 服务的数量 接下来，我们可以减少 taosAdapter 服务的数量
