Hey, Luke here, CTO at ClusterHQ.

As well as being proud of this company milestone, I can't wait to get powerstrip (https://github.com/clusterhq/powerstrip) and flocker (https://github.com/clusterhq/flocker) working together so that we can start composing flocker with other docker ecosystem tools.

It will be a great day that you can have a docker swarm with flocker and weave. Or kubernetes with flocker and socketplane. Or even mesosphere with rancher and calico ;)

We've got some pretty neat demos of powerstrip prototypes up here, fwiw: http://clusterhq.com/blog/powerstrip-prototype-docker-extens...

Any questions just shout!

Cheers, Luke

Interesting stuff & congratulations on the raise - having good persistence support around containers is indeed greatly needed!

What do you see flocker as adding to kubernetes? k8s looks like it is aiming to take care of networking & persistence, so I'm interested to hear what flocker brings to the table!

We* love kubernetes, and all the other orchestration frameworks, like Mesosphere, fleet, docker swarm, etc. We see flocker, our open-source project for managing data volumes, running beside these orchestrators. In fact, we've just released another open-source tool called powerstrip (https://github.com/ClusterHQ/powerstrip) which makes it possible to write adaptors for the Docker API so that a user can eventually use Flocker with Kubernetes.

Regarding how we are different, we focus only on managing persistent volumes, and as a specialist, will be able to do a lot more than something like kubernetes that is managing the entire application. If I had to guess, what you'd see with kubernetes, mesos, docker, etc is that they all support some basic data movement features, but if you want something more customized, like live migration, or true Disaster Recovery, you'd use Flocker, along side your orchestrator of choice.

*in case it wasn't clear, I work at ClusterHQ

I don't think it would be hard to use Kubernetes with Powestrip and Flocker. I and Luke worked on integrating Weave with Flocker together last week, and Powerstrip makes it really quite simple. There is not much that would get on the way of Kubernetes, if it moves a container, Flocker will move it's volume. That's the basics, of course, for something more advanced one will need to expose some features of Flocker in Kubernetes.

Congratulations Luke and team! The ClusterHQ crew is great to work with, they really get what we're trying to do with Docker, and they're providing great feedback on the best way to help the Docker ecosystem be successful, instead of getting in the way.

Whenever people ask me "I want to use the Docker ecosystem to distribute my product, what's the right way to do it?", I point to a handful of projects as examples to follow. ClusterHQ is definitely one of them. I'm tempted to point to other good examples here, but this is Luke's moment so I'll wait for a more appropriate occasion :)

Congratulations again!

Thanks Solomon! Great to be working with you and lots of other nice folks in the ecosystem. :)

Thanks. We are all very excited about this. :)

Happy to hear you're growing the SF office -- will be excellent to have more Docker hackers around!

I'm really excited about this. Stateful containers is something which needs addressing.

Thanks! We're excited to be focused solving state problems for containers. As they say, watch this space `:-)

Congratulations ClusterHQ team! Very excited about Powerstrip.

Thanks :-) Powerstrip will see a lot more adapters in the next few months - including one for flocker!

Congratulations!!!
