Ask HN: Is your Kubernetes production-grade?

Hi HN, I've seen plenty of Kubernetes clusters out there, but none met my definition of "production-grade".

I don't mean "is it used in production" - most of them are, but are still a work-in-progress and missing some configuration such as cross-AZ replication (most common), auto-scaling nodes, disaster recovery etc.

Are you satisfied with your cluster? is it mostly "done" or do you still have a large (3+) DevOps team working on it? for how long?
