import ( "k8s.io/kubernetes/pkg/registry/generic" ) // Create a new RESTOptions struct restOpts := &generic.RESTOptions{ Resource: "pods", Namespace: "default", } // Perform an HTTP GET request with the RESTOptions struct response, err := restOpts.Get().DoRaw() // Perform an HTTP POST request with the RESTOptions struct and request body requestBody := []byte(`{"apiVersion": "v1", "kind": "Pod", "metadata": {"name": "example-pod"}}`) response, err := restOpts.Post().Body(requestBody).DoRaw() // Perform an HTTP PUT request with the RESTOptions struct and URL parameter urlParam := "example-pod" response, err := restOpts.Put().Name(urlParam).Body(requestBody).DoRaw()These examples show how the RESTOptions struct can be used to make HTTP requests to a Kubernetes registry for creating, updating, and retrieving resources. It is an example of a package library in the Go programming language.
