I highly recommend Rook [1], which is based on Ceph, provides PersistentVolumes to k8s workloads and is also running on k8s itself.

I worked on Colossus at Google and Ceph is the closest thing out there. Gregory Farnum gave a great talk about it at the Open Source Summit 2017.

I heard from someone at a large company, though, that it's not getting a lot of love from Red Hat nowadays, even if you're a large paying customer. Now I'm curious.

I'm curious also. I don't have any special insight into RedHat, but rook went 1.0 just last week: https://blog.rook.io/rook-v1-0-a-major-milestone-689ca4c7550...

That announcement gave me the impression the project is making active progress.

I'm working on Rook+Ceph at Red Hat. Rook 1.0 was just released last week which added support for the very latest Nautilus release of Ceph.

Great to hear. I couldn't get more details from them, but it was something about both rebalancing and data recovery. They picked SwiftStack, which is at least in part open source. Maybe by now you have figured who that company is.

My team is still very interested in Ceph and Rook, for the record.

Really curious about Rook. The stakes of running something like that on K8S successfully seem quite a bit higher than stateless apps, and commensurately the rewards as well.

Big fan of rook myself. We took several nodes loaded with 16 disk drives and used Rook to make a Ceph and Minio cluster out of it. Great storage solution.

Have you done any disaster recovery exercises? We've started to play with it, but haven't gone that far yet.
