Overview ¶
Package genericapiserver contains code to setup a generic kubernetes-like API server. This does not contain any kubernetes API specific code. Note that this is a work in progress. We are pulling out generic code (specifically from pkg/master and pkg/apiserver) here. We plan to move this package into a separate repo on github once it is done. For more details: https://github.com/kubernetes/kubernetes/issues/2742

All these are subject to authorization and authentication. InsecureHandler -- an http.Handler which handles all the same endpoints as Handler, but no authorization and authentication is done.
Public methods:
HandleWithAuth -- Allows caller to add an http.Handler for an endpoint that uses the same authentication and authorization (if any is configured) as the GenericAPIServer's built-in endpoints. If the caller wants to add additional endpoints not using the GenericAPIServer's auth, then the caller should create a handler for those endpoints, which delegates the any unhandled paths to "Handler".
