Crashes immediately with Kubernetes 1.6

[jml]

I ran kubetop against my local minikube installation and got this error: 'schedulerName' are not among the specified fields for v1.PodSpec.

I tried kubectl get po immediately after, to confirm k8s was running in some mostly-working way, and it was indeed working.

I don't know if Kubernetes 1.6 is the main factor, but subject lines are hard.

Full output

Thanks!

It looks like this is due to a limitation of txkube - which is that it uses the Kubernetes 1.5 schema.

It's not immediately obvious to me what to do about this. Except to file an issue against txkube: LeastAuthority/txkube#121

This is still an issue:
