alt Hacker NewsPeople have it backwards.
If you have an app and you want to run a single app yeah silly to look for K8s.
If you have a beefy server or two you want to utilize fully and put as many apps on it without clashing dependencies you want to use K8s or docker or other containers. Where K8s enables you to go further.
Why would you want to use K8s for one or two beefy servers? It's designed for solving a different problem at a large scale.
