Will OpenStack in containers be a big topic of discussion. From a high-level I get some of the appeal. But are there improvements in Mitaka that lend itself to stateless compute?

top attended sessions at recent summits, @coreoslinux attends, @docker is discussed. Kubernetes is the new hot topic.

What do you mean stateless compute? Containers, cloud-native apps, serverless computing?

@stu The user survey shows big increase in use of kubernetes as opposed to docker swarm.

@kenhuiny Swarm seems to be confined to the All-Docker environment, whereas k8s seems to have broader appeal in more frameworks

Meaning the management layer running in containers ie Heat in a rkt container. It allows for versioning of the mgmt layer. But can OpenStack management nodes easily operate in such an infrastructure.

@kenhuiny user survey showed top 3 technologies of interest were 1) Containers 2) NFV & SDN, 3) Bare Metal.

It will certainly be discussed. I see OpenStack as very complementary as a platform to run your containers / orchestration system of choice on

@kenhuiny expect some LIVE DEMOS at the summit involving OpenStack & Kubernetes #shamelessplug

@sparkycollier OpenStack on k8s as an application, or OpenStack with k8s as a container scheduler for applications?

more noise has been made about containers *on* OpenStack but definitely lots of work being done on the backend on containerizing OpenStack itself. Main improvement in Mitaka from this perspective is probably Kolla upgrade support.

Also working on making Kolla a little bit more abstract, easier to plug in different orchestration options (Ansible, Mesos, Kubernetes)

@xsgordon what's the difference between Magnum and Kolla?
![](https://crowdspotsimages.s3-us-west-2.amazonaws.com/profile-images/dXNlcjp0d2l0dGVyOjIxMjUzNzg4MQ.jpeg)

Existing deployments will of course also need an upgrade path to get to containerized OpenStack in the first place (not an issue for greenfield).

Also, User Survey showed Magnum #1 project of interest (44%) followed closely by Manila.
