[atomic] OpenStack Magnum concerns about Project Atomic

[Steve Gordon <sgordon redhat com>]

Hi all,

Not sure if this is the right place as the Magnum folks are primarily using the Fedora Atomic images as their base but I was recently pointed to this IRC discussion where the Magnum folks outlined some of their concerns resulting from interacting with the Atomic images which are causing them to look elsewhere:

    http://eavesdrop.openstack.org/irclogs/%23openstack-containers/%23openstack-containers.2016-02-15.log.html

This is in some ways a continuation of this earlier thread:

    http://lists.openstack.org/pipermail/openstack-dev/2016-February/thread.html#85699

Trying to boil down the comments into a summary:

* Depending on timing age of components in Fedora Atomic leads to a need for Magnum folks to rebuild image, at least until such time as more of the pieces are containerized (k8s/etcd/flanel) [1].
* Rebuild image documentation lacks troubleshooting information (I encountered this myself, there are plenty of places for things to go off the rails in the compose and create-vm-disk steps and the tooling provides very limited error output in some cases). 
* Lack of clarity around if or when originally proposed build cadences will be hit for Fedora Atomic - I think this was originally proposed as 2-weekly but it's hard to tell if that has actually been hit to an outsider. To me it looks like yes [2] but do we record anywhere when a new build was pushed out to the mirrors as the current stable?
* Doesn't really feel like an active global community versus e.g. CoreOS. I know this is a challenging thing to "solve" but I list it as it is part of their concern, I myself have asked a question in the #atomic IRC and it was eventually answered but only when US East coast folks were up and awake again.

I know this is very high level feedback in many cases and difficult to action but wanted to highlight it . Scott has already answered my query on the Fedora cloud list w.r.t. containerization plans for the services mentioned which I think would help Magnum folks a lot [1], and I see we are apparently now doing two-weekly updates to the Fedora cloud image [2] though as I mentioned it would be great if we can illustrate the history of this in terms of regular builds produced/pushed.

Thanks,

Steve
