Golang thirdpartyresourcedata.ExtractApiGroupAndKind函數代碼示例

// InstallThirdPartyResource installs a third party resource specified by 'rsrc'.  When a resource is
// installed a corresponding RESTful resource is added as a valid path in the web service provided by
// the master.
//
// For example, if you install a resource ThirdPartyResource{ Name: "foo.company.com", Versions: {"v1"} }
// then the following RESTful resource is created on the server:
//   http://<host>/apis/company.com/v1/foos/...
