<p>I am creating a pod in k8 client go and making a watch to get notified for when the pod has completed so that i can read the logs of the pod. The watch interface doesnt seem to provide any events on the channel. Here is the code, how would I get notified that the pod status is now completed and is ready to read the logs</p>
<pre class="lang-golang prettyprint-override"><code>func readLogs(clientset *kubernetes.Clientset) {
// namespace := &quot;default&quot;
// label := &quot;cithu&quot;
var (
    pod *v1.Pod
    // watchface watch.Interface
    err error
)
// returns a pod after creation

pod, err = createPod(clientset)
fmt.Println(pod.Name, pod.Status, err)

if watchface, err = clientset.CoreV1().Pods(namespace).Watch(metav1.ListOptions{
    LabelSelector: pod.Name,
}); err != nil {
    log.Fatalf(err.Error())
}

// How do I get notified when the pod.Status == completed
}
</code></pre>

<p>The events can be listed using the following snippet. You can then process the pod events as needed.</p>
<pre class="lang-golang prettyprint-override"><code>label := &quot;&quot;
for k := range pod.GetLabels() {
    label = k
    break
}
watch, err := clientset.CoreV1().Pods(namespace).Watch(metav1.ListOptions{
    LabelSelector: label,
})
if err != nil {
    log.Fatal(err.Error())
}
go func() {
    for event := range watch.ResultChan() {
        fmt.Printf(&quot;Type: %v\n&quot;, event.Type)
        p, ok := event.Object.(*v1.Pod)
        if !ok {
            log.Fatal(&quot;unexpected type&quot;)
        }
        fmt.Println(p.Status.ContainerStatuses)
        fmt.Println(p.Status.Phase)
    }
}()
time.Sleep(5 * time.Second)
</code></pre>
