Kubernetes is for when you need to run thousands of containers on a large cluster and you want to be able to do it both locally (on-prem) and in the cloud. It's for cases where you already have operations staff who can manage it on-prem for you. It's for cases where you have a dozen teams and you want any developer from any team to be able to spin up a fresh instance of software from any other team for dev, testing, etc., all on one pool of shared hardware. It's not for your blog, and it's not for your startup of 10 people where you can just use purely managed services on AWS or Google Cloud. (That said, there's obviously nothing wrong with using a personal blog as a playground to learn new technologies.)
