available to actually setup/deploy/run kubernetes, when operators are likely still just struggling to run openstack itself (at least operators are getting used to the openstack warts, a new set of kubernetes warts could not be so helpful).<o:p></o:p></p>

I'm pleased to announce the development of a new project Kolla which is Greek for glue :). Kolla has a goal of providing an implementation that deploys OpenStack using Kubernetes and Docker. This project will begin as a StackForge project separate from the
TripleO/Deployment program code base. Our long term goal is to merge into the TripleO/Deployment program rather then create a new program.<br>

<p class="MsoNormal" style="margin-left:36.0pt"><span style="font-size:11.5pt;font-family:"Arial","sans-serif"">Docker is a container technology for delivering hermetically sealed applications and has about 620 technical contributors [1]. We intend to produce
docker images for a variety of platforms beginning with Fedora 20. We are completely open to any distro support, so if folks want to add new Linux distribution to Kolla please feel free to submit patches :)<br>

Kubernetes is more then just a scheduler, it provides additional functionality such as load balancing and scaling and has a significant roadmap.<br>

The #tripleo channel on Freenode will be used for Kolla developer and user communication. Even though we plan to become part of the Deployment program long term, as we experiment we believe it is best to hold a separate weekly one hour IRC meeting on Mondays
at 2000 UTC in #openstack-meeting [3].<br>

This project has been discussed with the current TripleO PTL (Robert Collins) and he seemed very supportive and agreed with the organization of the project outlined above. James Slagle, a TripleO core developer, has kindly offered to liase between Kolla and
the broader TripleO community. <br>
