<html><body bgcolor="#FFFFFF"><p>Thanks Steve. We indeed have been using the image built by Yolanda's DIB elements and things have been stable. Dane and I have resolved the problems with the load balancer at least for the LBaaS v1. For LBaaS v2, we need to build a new image with Kubernetes 1.3 and we just got one built today.<br>Ton,<br><br><img width="16" height="16" src="cid:1__=07BB0AAFDFB3DAF98f9e8a93df938690918c07B@" border="0" alt="Inactive hide details for "Steven Dake (stdake)" ---09/27/2016 10:18:07 PM---Dane, I’ve heard Yolanda has done good work on ma"><font color="#424282">"Steven Dake (stdake)" ---09/27/2016 10:18:07 PM---Dane, I’ve heard Yolanda has done good work on making disk image builder build fedora atomic properl</font><br><br><font size="2" color="#5F5F5F">From: </font><font size="2">"Steven Dake (stdake)" <stdake@cisco.com></font><br><font size="2" color="#5F5F5F">To: </font><font size="2">"OpenStack Development Mailing List (not for usage questions)" <openstack-dev@lists.openstack.org></font><br><font size="2" color="#5F5F5F">Date: </font><font size="2">09/27/2016 10:18 PM</font><br><font size="2" color="#5F5F5F">Subject: </font><font size="2">Re: [openstack-dev] [magnum] Fedora Atomic image that supports kubernetes external load balancer (for stable/mitaka)</font><br><hr width="100%" size="2" align="left" noshade style="color:#8091A5; "><br><br><br><font face="Calibri">Dane,</font><br><font face="Calibri"> </font><br><font face="Calibri">I’ve heard Yolanda has done good work on making disk image builder build fedora atomic properly consistently. This may work better than the current image building tools available with atomic if you need to roll your own. Might try pinging her on irc for advice if you get jammed up here. Might consider consulting tango as well as I handed off my knowledge in this area to him first and he has distributed to the rest of the Magnum core reviewer team. I’m not sure if tango and Yolanda have synced on this – recommend checking with them.</font><br><font face="Calibri"> </font><br><font face="Calibri">Seems important to have a working atomic image for both Mitaka and Newton.</font><br><font face="Calibri"> </font><br><font face="Calibri">Regards</font><br><font face="Calibri">-steve</font><br><font face="Calibri"> </font><br><font face="Calibri"> </font><br><b><font face="Calibri">From: </font></b><font face="Calibri">"Dane Leblanc (leblancd)" <leblancd@cisco.com></font><b><font face="Calibri"><br>Reply-To: </font></b><font face="Calibri">"OpenStack Development Mailing List (not for usage questions)" <openstack-dev@lists.openstack.org></font><b><font face="Calibri"><br>Date: </font></b><font face="Calibri">Thursday, September 8, 2016 at 2:18 PM</font><b><font face="Calibri"><br>To: </font></b><font face="Calibri">"OpenStack Development Mailing List (not for usage questions)" <openstack-dev@lists.openstack.org></font><b><font face="Calibri"><br>Subject: </font></b><font face="Calibri">[openstack-dev] [magnum] Fedora Atomic image that supports kubernetes external load balancer (for stable/mitaka)</font><br><font face="Times New Roman"> </font><br><font face="Calibri">Does anyone have a pointer to a Fedora Atomic image that works with stable/mitaka Magnum, and supports the kubernetes external load balancer feature [1]?</font><br><font face="Calibri"> </font><br><font face="Calibri">I’m trying to test the kubernetes external load balancer feature with stable/mitaka Magnum.
