Thanks Ton, When is the Docker libnetwork functionality forecasted to be available ?

Hi Greg, This is a capability that we are working on at this time: enabling Docker libnetwork using the Kuryr driver. This will let you set up networks where the containers are connected to and they will be allocated unique routable IP. In the current default networking mode, you can still let container provides service to each other through Docker port mapping. The end point for the container service would be the IP address of the VM where the container is hosted together with the port mapped. You just cannot ping from one container to another across VM's in this mode.

I noticed that Docker-Swarm’s Container Networking Solution seems to simply be an SNAT on its swarm-node VM. And noticed that Docker-Swarm assigns the same Container subnet to each swarm-node VM … and re-uses Container IP Addresses from this subnet across swarm-node VMs. Given this … it does not appear that Docker-Swarm can support networking between two containers on different swarm-node VMs. Is this True ? OR Is there a configuration option, thru Magnum or Docker-Swarm to enable this inter-node inter-container Networking ?
