You need to see Kubernetes as a wrapper of the init thread (systemd).

If you fought with cgroup to tame resource (memory, cpu) consumption you know.

You get also controlled rollout for free.

Likewise, it’s also a platform so you get installation receipts of third party software’s for free.

You install the Prometheus operator and, bam, you get declarative monitoring as code for free.

The ticket entry is not free but once you got it, it’s repeatable and durable.

I use most of this chart:

There is more but it asks a real blog.
