I used to say the same thing, but now that there is so much K8s knowledge out there, I think it's the wrong question to ask.

You probably don't need kubernetes, but if you already have a k8s cluster and someone who has done it,, with 10 to 20 minutes of work you can deploy your app/service in a highly available. Even if you don't have a k8s cluster yet, these days you can provision one easily without advanced levels of knowledge. Even just zero-down time deploys make k8s a good choice for a small shop. You basically get it for free with K8s.
