Open Stack

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.
Ton,

Dane,

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.

Seems important to have a working atomic image for both Mitaka and Newton.

Regards
-steve

 Subject: [openstack-dev] [magnum] Fedora Atomic image that supports
 kubernetes external load balancer (for stable/mitaka)

 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]?

 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:
       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: SubnetID is required

 I verified that I have the subnet-id field set in the [LoadBalancer]
 section in /etc/sysconfig/kube_openstack_config.

 I’ve tried this using the following Fedora Atomic images from [2]:
       fedora-21-atomic-5.qcow2
       fedora-21-atomic-6.qcow2
       fedora-atomic-latest.qcow2

 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:
       https://github.com/GoogleCloudPlatform/kubernetes/pull/12203
       https://github.com/GoogleCloudPlatform/kubernetes/pull/12262
       https://github.com/GoogleCloudPlatform/kubernetes/pull/12288
 The first of these patches, “Pass SubnetID to vips.Create()”, is
 apparently necessary to fix the “SubnetID is required” error shown above.

 According to the Magnum external load balancer blueprint [3], the
 fedora-21-atomic-6 image should include the above 3 fixes:
       “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”
 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:
       [minion at k8-64n4bna2v6-0-ffukgho7n7tf-kube-master-fif5b6pivdmy
       sysconfig]$ rpm -qa | grep kube
       kubernetes-node-1.2.0-0.15.alpha6.gitf0cd09a.fc23.x86_64
       kubernetes-1.2.0-0.15.alpha6.gitf0cd09a.fc23.x86_64
       kubernetes-client-1.2.0-0.15.alpha6.gitf0cd09a.fc23.x86_64
       kubernetes-master-1.2.0-0.15.alpha6.gitf0cd09a.fc23.x86_64
       [minion at k8-64n4bna2v6-0-ffukgho7n7tf-kube-master-fif5b6pivdmy
       sysconfig]$

 Does anyone have a pointer to a Fedora Atomic image that contains the 3
 kubernetes fixes listed earlier (and works with stable/mitaka)?

 Thanks!
 -Dane
