How do I capture the output of oc command : oc get endpoints -n default -o yaml kubernetes inside a redhat ocp container

Question

I tried using clientset.CoreV1().Endpoints(namespace).Get(context.TODO(),name string , metav1.GetOptions{})

endpoints, err2 := clientset.CoreV1().Endpoints(namespace2).Get(context.TODO(), namespace2, metav1.GetOptions{})
    if err2 != nil {
            log.Println(err2.Error())
    }

    fmt.Printf("GetPodList There are %v endpoints in the cluster\n", (endpoints))

But I am unsure of the argument to give for name string (the second argument) and metav1.GetOptions{}. (third argument)

Answer 1

You should use the List function rather than Get: List allows you to retrieve multiple endpoints matching certain criteria, Get allows you to retrieve a specific endpoint (by name).

Thus:

endpoints, err := clientset.CoreV1().Endpoints(namespace2).List(context.TODO(), metav1.ListOptions{})
// ...
fmt.Printf("GetPodList there are %v endpoints in the cluster\n", len(endpoints.Items)

If you want all the endpoints in a namespace, you don’t need to specify any list options and passing an empty structure is fine.
