// Package scheme contains utilities for gradually building Schemes,
|
|
// which contain information associating Go types with Kubernetes
|
|
// groups, versions, and kinds.
|
|
//
|
|
// Each API group should define a utility function
|
|
// called AddToScheme for adding its types to a Scheme:
|
|
//
|
|
// // in package myapigroupv1...
|
|
// var (
|
|
// SchemeGroupVersion = schema.GroupVersion{Group: "my.api.group", Version: "v1"}
|
|
// SchemeBuilder = &scheme.Builder{GroupVersion: SchemeGroupVersion}
|
|
// AddToScheme = SchemeBuilder.AddToScheme
|
|
// )
|
|
//
|
|
// func init() {
|
|
// SchemeBuilder.Register(&MyType{}, &MyTypeList)
|
|
// }
|
|
// var (
|
|
// scheme *runtime.Scheme = runtime.NewScheme()
|
|
// )
|
|
//
|
|
// This also true of the built-in Kubernetes types. Then, in the entrypoint for
|
|
// your manager, assemble the scheme containing exactly the types you need,
|
|
// panicing if scheme registration failed. For instance, if our controller needs
|
|
// types from the core/v1 API group (e.g. Pod), plus types from my.api.group/v1:
|
|
//
|
|
// func init() {
|
|
// utilruntime.Must(myapigroupv1.AddToScheme(scheme))
|
|
// utilruntime.Must(kubernetesscheme.AddToScheme(scheme))
|
|
// }
|
|
//
|
|
// func main() {
|
|
// mgr := controllers.NewManager(context.Background(), controllers.GetConfigOrDie(), manager.Options{
|
|
// Scheme: scheme,
|
|
// })
|

// // ...
