UPDATE: This issue has been resolved. Please see the update blog post

One of the features of the Fedora Atomic Host 25 release was decoupling Kubernetes from the base ostree for Atomic (this is true of the current CentOS Atomic Host as well). That is, Kubernetes is no longer in the base install, you need to add it in as system containers and/or an overlay. This is a step forwards for Atomic because it means that users can continuously update Atomic, and update Kubernetes on a different schedule which works for their cluster. Since Kubernetes gets released four times a year, this lets developers update to the latest version, and production users stay on their production version.

However, when we released Fedora Atomic 25, the containerized install wasn’t quite ready, and there were issues with installing Kubernetes using package layering which we hadn’t anticipated. At the time, we expected those issues to be resolved within a few days. Instead, some have taken longer than expected and are still unresolved or waiting on PR review.

The Fedora Atomic team is hard at work on getting a solution out for Kubernetes users and expect to have one before the holidays. If you are able to help with building or testing, please speak up on the Atomic Development mailing list; we could use your help. If you can’t help, wait for us to publish documentation of the new containerized Kubernetes before you rebase to 25. Bug fixes are still available for the Fedora 24 tree.

If you use Fedora Atomic, but do not use Kubernetes, this issue does not affect you. If you are using Kubernetes based on a containerized install already (via Kubeadm or Hyperkube), this issue is also not a problem for you. Unaffected users should rebase to Fedora Atomic 25 for updated libraries and platforms, including the latest OpenShift and Docker support.

Thanks for your patience, and we’ll see you on the mailing lists and IRC with any other issues.
