Frankly, I don’t understand what part of the press release contradicts with
Fuel mission.

Current Fuel mission is “To streamline and accelerate the process of
deploying, testing and maintaining various configurations of OpenStack at
scale.” which means we are not bound to any specific technology when
deploying OpenStack.

At the moment Fuel deploys RPM/DEB packages using Puppet and Fuel specific
orchestration mechanism. We are not going to drop this approach
immediately, it works quite well and we are working hard to make things
better (including ability to upgrade). But we also keep in mind that
technologies are constantly changing and we’d like to benefit of this
progress. That is why we are now looking at Docker containers and
Kubernetes. Our users know that it is not our first experience of trying to
use containers. Fuel releases prior to 9.0 used to deploy Fuel services in
containers on the Fuel admin node.

Many of you know how difficult it is to upgrade OpenStack clusters. We hope
that containers could help us to solve not all but some of problems that we
encounter when upgrading cluster. Maintaining and hence upgrade of
OpenStack clusters is a part of Fuel mission and we are just trying to find
a way how to do things.

Why not Kolla but Fuel-ccp? It is not a secret that Fuel is driven by
Mirantis. At Mirantis we deploy and maintain OpenStack. In attempts to find
a way how to make OpenStack easily maintainable, some of Mirantis folks
spent some time to contribute to Kolla and Mesos. But there were some
concerns that were discussed several times (including this Kolla spec
https://review.openstack.org/#/c/330575) that would make it not so easy to
use Kolla containers for our use cases. Fuel-ccp is just an attempt to
address these concerns. Frankly, I don’t see anything bad in having more
than one set of container images (like we have more than one set of RPM/DEB
distributions).

Those concerns are, for example, container images should not be bound to
any specific deployment technology. Containers in some sense are a similar
concept to RPM/DEB packages and it does not matter what deployment tool
(puppet, ansible) one uses to install them. There should be mature CI
pipeline for building/testing/publishing images. There should be a
convenient way (kind of DSL) to deal with dozens of images. I’d like to
avoid discussing this here once again.

Fuel-ccp repositories are public, everyone is welcome to participate. I
don’t see where we violate “4 opens”. These repos are now experimental. At
the moment the team is working on building CI pipeline and developing
functional tests that are to be run as a part of CI process. These repos
are not to be a part of Fuel Newton release. From time to time we add and
retire git repos and it is a part of development process. Not all these
repos are to become a part of Big tent.
