Like with anything, it should be evaluated based on what your needs are.

For a simple deploy you probably don't need Kubernetes or even containers.

If you are running containers, you'll need a mechanism for running them. And maybe at some point you want something to recreate them when they die or become unhealthy. Maybe you want to run multiple containers, and you want to do rolling deploys of them. Maybe you want to run them on multiple hosts and network them together. Maybe you want to be able to attach a persistent disk to some of them, or interface with some secrets management software. And maybe you want a single, well-supported API for doing all of the above.

There's a lot more that can be said about Kubernetes; it offers a lot out of the box as well as an API for extending it when you need behavior it doesn't provide.
