<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Seems important to have a working atomic image for both Mitaka and Newton.<o:p></o:p></p>

<p class="MsoNormal">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]?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’m trying to test the kubernetes external load balancer feature with stable/mitaka Magnum. However, when I try to bring up a load-balanced service, I’m seeing these errors in the kube-controller-manager logs:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><i><span style="font-size:10.0pt;font-family:Tahoma;background:white">E0907 16:26:54.375286 1 servicecontroller.go:173] Failed to process service delta. Retrying: failed to create external load balancer for
service default/nginx-service: <span style="color:red">SubnetID is required</span></span></i><o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I verified that I have the subnet-id field set in the [LoadBalancer] section in /etc/sysconfig/kube_openstack_config.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’ve tried this using the following Fedora Atomic images from [2]:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">fedora-21-atomic-5.qcow2<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">fedora-21-atomic-6.qcow2<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">fedora-atomic-latest.qcow2<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">According to the Magnum external load balancer blueprint [3], there were 3 patches in kubernetes that are required to get the OpenStack provider plugin to work in kubernetes:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><a href="https://github.com/GoogleCloudPlatform/kubernetes/pull/12203">https://github.com/GoogleCloudPlatform/kubernetes/pull/12203</a><br>
<a href="https://github.com/GoogleCloudPlatform/kubernetes/pull/12262">https://github.com/GoogleCloudPlatform/kubernetes/pull/12262</a><br>
<a href="https://github.com/GoogleCloudPlatform/kubernetes/pull/12288">https://github.com/GoogleCloudPlatform/kubernetes/pull/12288</a><o:p></o:p></p>
<p class="MsoNormal">The first of these patches, “Pass SubnetID to vips.Create()”, is apparently necessary to fix the “SubnetID is required” error shown above.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">According to the Magnum external load balancer blueprint [3], the fedora-21-atomic-6 image should include the above 3 fixes:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">“<i>Our work-around is to use our own custom Kubernetes build (version 1.0.4 + 3 fixes) until the fixes are released. This is in image fedora-21-atomic-6.qcow2</i>”<o:p></o:p></p>
<p class="MsoNormal">However, I’m still seeing the “SubnetID is required” errors with this image downloaded from [2]. Here are the kube versions I’m seeing with this image:<o:p></o:p></p>

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Does anyone have a pointer to a Fedora Atomic image that contains the 3 kubernetes fixes listed earlier (and works with stable/mitaka)?<o:p></o:p></p>
