Kubernetes is good for two things. Zero downtime deployments and self-healing (where the looping state mechanism comes in). There are people who want k8s to handle every single operation that can run on a server, do not listen to those kinds of people they will lead you astray.

It's the industry standard for running and shipping containerized applications, at least for the ones which are more complex and/or dynamic than an application container and maybe 1-2 databases. It provides a well defined and stable orchestration API which is also quite capable. It's even sometimes worthwhile to spin up a single node cluster for that reason. Does not mean it is perfect, is it sometimes a bit complex? yes, is it verbose? yes, could the established ecosystem be better (thinking about e.g. helm)? yes. But at some point it's still easier with k8s than without it.

It is of course not the best choice for everything, there are enough things where you better just spin up a VM and deploy directly or with only a simple container runtime if you use containers.
