import ( "fmt" "os" "k8s.io/client-go/tools/clientcmd" "k8s.io/kubernetes/pkg/kubectl/cmd/util" ) func main() { factory := util.NewFactory(nil) // Get the client configuration for the default context config, err := factory.ToRawKubeConfigLoader().ClientConfig() if err != nil { fmt.Fprintf(os.Stderr, "Error getting client config: %s", err) os.Exit(1) } // Use the configuration to create a Kubernetes client client, err := factory.KubernetesClientSet() if err != nil { fmt.Fprintf(os.Stderr, "Error creating Kubernetes client: %s", err) os.Exit(1) } // ... }This code creates a new client configuration factory, and then uses it to get the client configuration for the default context in the user's kubeconfig file. It then uses that configuration to create a Kubernetes client. This client can be used to interact with the Kubernetes API, such as creating and modifying Kubernetes objects. Overall, the "go k8s.io/kubernetes/pkg/kubectl/cmd/util" package library is a useful tool for working with Kubernetes clusters in Go code.
