Question

我阅读了相关问题，但没有一个与我的问题完全吻合。但是，我的问题非常接近this one，但解决方案并不重要，因为我的配置与解决方案中详述的配置相符。

我在Swarm集群中集成了3个节点（VM），其中包含一个管理器。创建覆盖网络并将容器作为附加到此网络的服务启动后，来自一个主机的容器无法访问在其他主机上运行的容器。

注1：docker inspect <network>仅显示当前主机上运行的容器。

注2：ping和curl都适用于当前主机上运行的容器IP。

注意3：如果没有放入特定的网络，可以从evrywhere访问容器，我可以ping docker 172.17.0子网中的所有容器IP。它仍然无法在覆盖网络中工作。

请在下面找到常用信息，谢谢你的帮助。
