Who is using rkt in production? I'm working on a system from scratch and planning on using k8s and just assumed docker would be the container engine of choice, but the more I hear/ read about rkt the more it seems like the better choice.

We will be as soon as it has the same level of support in Kubernetes.

  Should be around 1.6 or 1.7 from a talk given in December by one of the core rkt team. Logging changes and being able to 'exec' into a container seem to be the main bugbears at the moment (may be other things but this was my take-away from the talk). I looked into this on the 1.4 kubernetes release but ended up with file descriptors not being freed up leading to a very unstable kubernetes cluster nodes. We are really enjoying using Ceph under rkt-fly[1] upon CoreOS though. [1] https://coreos.com/rkt/docs/latest/running-fly-stage1.html https://coreos.com/rkt/docs/latest/running-fly-stage1.html

BlaBlaCar have been using rkt since some really early version. Simon Lallemand gave a talk in Berlin at the CoreOS meetup about it. I don't recall it being recorded, though there is a blog entry covering some of the details[1]. Interesting how they built a lot of tooling for the container building and management before other ways appeared, and the approach they took to it.
