Span a swarm mode cluster over multiple cloud providers

Question

E.g a virtual machine on DigitalOcean and another on azure. Both have a public IP and the necessary docker swarm ports can be opened. Is there a way to create a docker swarm joining these 2 machines?

Answer 1

I think you can see at rancher-os and use this tutorial Link the whole point is that RacherOS uses its own network adapter
