# Kube OpenAPI
This repo is the home for Kubernetes OpenAPI discovery spec generation. The goal
is to support a subset of OpenAPI features to satisfy kubernetes use-cases but
implement that subset with little to no assumption about the structure of the
code or routes. Thus, there should be no kubernetes specific code in this repo.
There are two main parts:
- A model generator that goes through .go files, find and generate model
definitions.
- The spec generator that is responsible for dynamically generate
the final OpenAPI spec using web service routes or combining other
OpenAPI/Json specs.
