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

<br>
<span style="font-family:Calibri">I created a Docker-Swarm bay and successfully launched some simple containers.</span><br>
<br>
<span style="font-family:Calibri">I noticed that Docker-Swarm’s Container Networking Solution seems to simply be an SNAT on its swarm-node VM.</span><br>
<span style="font-family:Calibri">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.</span><br>
<br>
<span style="font-family:Calibri">Given this … it does not appear that Docker-Swarm can support networking between two containers on different swarm-node VMs.</span><br>
<span style="font-family:Calibri">Is this True ?</span><br>
<span style="font-family:Calibri">OR</span><br>
<span style="font-family:Calibri">Is there a configuration option, thru Magnum or Docker-Swarm to enable this inter-node inter-container Networking ?</span><br>
