<html><body bgcolor="#FFFFFF"><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>Ton Ngo,<br> <br><br><img width="16" height="16" src="cid:1__=07BBF566DFEECE728f9e8a93df938690918c07B@" border="0" alt="Inactive hide details for "Waines, Greg" ---07/19/2016 11:12:50 AM---I have successfully setup devstack with Magnum, following "><font color="#424282">"Waines, Greg" ---07/19/2016 11:12:50 AM---I have successfully setup devstack with Magnum, following this link <a href="https://github.com/openstack/mag">https://github.com/openstack/mag</a></font><br><br><font size="2" color="#5F5F5F">From: </font><font size="2">"Waines, Greg" <Greg.Waines@windriver.com></font><br><font size="2" color="#5F5F5F">To: </font><font size="2">"openstack-dev@lists.openstack.org" <openstack-dev@lists.openstack.org></font><br><font size="2" color="#5F5F5F">Date: </font><font size="2">07/19/2016 11:12 AM</font><br><font size="2" color="#5F5F5F">Subject: </font><font size="2">[openstack-dev] [Magnum] Does Docker-Swarm not support inter-node/vm inter-container networking ?</font><br><hr width="100%" size="2" align="left" noshade style="color:#8091A5; "><br><br><br><font face="Calibri">I have successfully setup devstack with Magnum,</font><br><font face="Calibri">following this link </font><a href="https://github.com/openstack/magnum/blob/master/doc/source/dev/quickstart.rst#building-and-using-a-swarm-bay"><u><font color="#0563C1" face="Calibri">https://github.com/openstack/magnum/blob/master/doc/source/dev/quickstart.rst#building-and-using-a-swarm-bay</font></u></a><br><font face="Calibri"> </font><br><font face="Calibri">I created a Docker-Swarm bay and successfully launched some simple containers.</font><br><font face="Calibri"> </font><br><font face="Calibri">I noticed that Docker-Swarm’s Container Networking Solution seems to simply be an SNAT on its swarm-node VM.</font><br><font face="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.</font><br><font face="Calibri"> </font><br><font face="Calibri">Given this … it does not appear that Docker-Swarm can support networking between two containers on different swarm-node VMs.</font><br><font face="Calibri">Is this True ?</font><br><font face="Calibri">OR</font><br><font face="Calibri">Is there a configuration option, thru Magnum or Docker-Swarm to enable this inter-node inter-container Networking ?</font><br><font face="Calibri"> </font><br><font face="Calibri">Greg.</font><br><font face="Calibri"> </font><tt>__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)<br>Unsubscribe: OpenStack-dev-request@lists.openstack.org?subject:unsubscribe<br></tt><tt><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</a></tt><tt><br></tt><br><br><BR>
