import ( admission "k8s.io/kubernetes/pkg/admission" ) func MyAdmissionController() admission.Handler { return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { attrs := admission.ExtractAttributes(r) name := attrs.GetName() // Do something based on the controller name }) }In this example, we define a custom admission controller by creating an HTTP handler function that takes a `http.ResponseWriter` and `http.Request` as arguments. We then extract the admission controller's attributes from the request using `ExtractAttributes`, and use `GetName` to get the name of the controller. We can use this name to make decisions about how to handle the request. Therefore, the package library for `k8s.io/kubernetes/pkg/admission` is Kubernetes.
