Developers use Kubernetes to turn their individual containers and virtual machines into full fledged, working applications.
Modern apps will often consist of a bunch of containers doing separate things that need to work together. Kubernetes orchestrates these containers and takes care of exposing them to people like you and me.
You can generally split the “point” of Kubernetes into three buckets: container health, networking, and configuration. The whole Kubernetes ecosystem is complicated and intense, and it’s not for everyone or every app.
