Ask HN: What are your biggest pain points working with Kubernetes?

I've worked with Kubernetes at a small startup now and we've had some challenges with it. Wiring up a deployment pipeline and figuring out how to work effectively with Helm took us some time. We also had to invest a lot more than we expected in working with other developers to teach Kubernetes concepts. It really, in hindsight, was probably overkill for our use case.

What are some of the biggest challenges that you've had in working with Kubernetes? How did you solve some of them?
