Currently we are testing kubernetes 1.10 in our CI, with cri-o 1.10. But the newest version 1.11, was released a couple of weeks ago.
We are also testing OpenShift 3.9 (which uses k8s 1.9) using cri-o 1.9 on our Fedora jobs.

Which version(s) of kubernetes should we support?
Currently I think that there is no statement of which version of k8s we support, we only have the reference of what we use in the CI here: https://github.com/kata-containers/runtime/blob/master/versions.yaml#L163

We have mainly two options here:

1. Support only the latest version.

2. Support the versions that CRI-O support? https://github.com/kubernetes-incubator/cri-o#compatibility-matrix-cri-o---kubernetes-clusters

   • This will require more CI jobs.

Also to take in consideration, we currently do some basic testing for k8s, but in the near future we should add e2e testing.
