 How does kube-apiserver know what to do when it accepts our request? Well, there's a pretty complicated series of steps that happen _before_ any requests are served. Let's start at the beginning, from when the binary is first run:
 
-1. When the `kube-apiserver` binary is run, it [creates a server chain](https://github.com/kubernetes/kubernetes/blob/master/cmd/kube-apiserver/app/server.go#L119), which allows apiserver aggregation. This is basically a way of supporting multiple apiservers (we don't need to worry about this).
-1. When this happens, a [generic apiserver is created](https://github.com/kubernetes/kubernetes/blob/master/cmd/kube-apiserver/app/server.go#L149) that serves as a default implementation.

 1. The generated OpenAPI schema populates the [apiserver's configuration](https://github.com/kubernetes/apiserver/blob/7001bc4df8883d4a0ec84cd4b2117655a0009b6c/pkg/server/config.go#L149).
 1. kube-apiserver then iterates over all the API groups specified in the schema and configures a [storage provider](https://github.com/kubernetes/kubernetes/blob/c7a1a061c3dc5acabcc0c35b3b96a6935dccf546/pkg/master/master.go#L410) for each that serves as a generic storage abstraction. This is what kube-apiserver talks to when it accesses or mutates the state of a resource.
 1. For every API group it also iterates over each of the group versions and [installs the REST mappings](https://github.com/kubernetes/apiserver/blob/7001bc4df8883d4a0ec84cd4b2117655a0009b6c/pkg/endpoints/groupversion.go#L92) for every HTTP route. This allows kube-apiserver to map requests and be able to delegate off to the correct logic once it finds a match.
