[Question] How to build docker swarm cluster across cloud platforms

[azi03]

I try to deploy docker between multiple shared clouds For swarm cluster, the cluster itself can be deployed successfully, and the services can be distributed and deployed on the hosts in the cluster, but the task containers cannot communicate with each other. The task can only be accessed through the host port where the task is located through the published port of the address network. Other hosts have corresponding listening ports, but they can't access the services normally. Swarm cluster and its creation both use -- advertise address R parameter, which is specified as the corresponding public IP of each server. All network ports between servers have been opened, including all TCP and UDP ports. The TCP and UDP communication between servers has been determined to be smooth. What else can we do to realize the interworking between task containers across cloud platforms under this architecture.

In addition, weave network can realize interoperability between containers across cloud platforms, but it can't be used for docker swarm deployment services, so it can't use its dynamic service management capability.

Thank you very much!

In addition, the docker version is docker version 20.10.5, build 55c4c88, and the operating system is CentOS 7.8
