import ( "fmt" "k8s.io/kubernetes/pkg/client/unversioned" "k8s.io/kubernetes/pkg/client/unversioned/event" ) func handleEvent(obj interface{}) { event := obj.(*core.Event) fmt.Printf("New event: %s\n", event.Message) } func main() { config := &unversioned.Config{} client := unversioned.NewOrDie(config) // Watch for new events watchlist := cache.NewListWatchFromClient(client, "events", "", fields.Everything()) _, controller := cache.NewInformer( watchlist, &core.Event{}, time.Second * 0, cache.ResourceEventHandlerFuncs{ AddFunc: handleEvent, }, ) controller.Run(nil) }In this example, we create a Kubernetes client and use it to watch for new events. Whenever a new event is received, the `handleEvent` function will be called, which simply prints out the message of the event. This code makes use of the `cache` package from the `k8s.io/client-go` library, which is a dependency of the `k8s.io/kubernetes/pkg/client/unversioned` package. Overall, the `k8s.io/kubernetes/pkg/client/unversioned` package provides a powerful and easy-to-use interface for interacting with the Kubernetes API in Go.
