It appears that the bug is in Kubernetes. The Go RFC 3339 Micro format is 2006-01-02T15:04:05.999999999Z07:00, while the Kubernetes RFC 3339 Nano format is 2006-01-02T15:04:05.000000Z07:00.

However, it will take a very long time for that change to make it into Kubernetes if they even decide to accept it. So probably changing the k8s-openapi project is a better bet.

I’m going to file an issue in Kubernetes anyway, since it does seem to be a relevant issue for them to consider.

I’ll file a bug upstream on k8s-openapi, but I think we should probably manually serialize the lease spec until that fix is made.
