<p>I need to watch (and wait) until a POD is deleted. I need to this is because I need to start a second pod (with the same name) immediately after the first one has been deleted.</p>
<p>This is what I'm trying:</p>
<pre><code>func (k *k8sClient) waitPodDeleted(ctx context.Context, resName string) error {
    watcher, err := k.createPodWatcher(ctx, resName)
    if err != nil {
        return err
    }

    defer watcher.Stop()

    for {
        select {
        case event := &lt;-watcher.ResultChan():

            if event.Type == watch.Deleted {
                k.logger.Debugf(&quot;The POD \&quot;%s\&quot; is deleted&quot;, resName)

                return nil
            }

        case &lt;-ctx.Done():
            k.logger.Debugf(&quot;Exit from waitPodDeleted for POD \&quot;%s\&quot; because the context is done&quot;, resName)
            return nil
        }
    }
}
</code></pre>
<p>The problem with this approach is that when I get the <code>Deleted</code> event, is when the POD receives the event for deletion, but not when it is actually deleted. Doing some extra tests I ended debugging the process with this code:</p>
<pre><code>case event := &lt;-watcher.ResultChan():

    if event.Type == watch.Deleted {
        pod := event.Object.(*v1.Pod)
        k.logger.Debugf(&quot;EVENT %s PHASE %s MESSAGE %s&quot;, event.Type, pod.Status.Phase, pod.Status.Message)
    }
</code></pre>
<p>The log result for this is:</p>
<pre><code>2022-02-15T08:21:51 DEBUG EVENT DELETED PHASE Running MESSAGE
2022-02-15T08:22:21 DEBUG EVENT DELETED PHASE Running MESSAGE
</code></pre>
<p>I'm getting two Deleted events. The first one right away I send the delete command. The last one when the pod is effectively deleted from the cluster.</p>
<p>My questions are:</p>
<ul>
<li>Why I'm getting two Deleted events? How can I differentiate one from another? I've tried to compare the two events and they seems exactly the same (except the timestamps)</li>
<li>What is the best approach to watch and wait for a pod deletion, so I can immediately relaunch it? should I poll the API until the pod is not returned?</li>
</ul>
<p>The usecase I'm trying to solve:
In my application there is a feature to replace a tool with another with different options. The feature needs to delete the pod that contains the tool and relaunch it with another set of options. In this scenario I need to wait for the pod deletion so I can start it again.</p>
<p>Thanks in advance!</p>

<p>As I said in the comments, the real problem was the watcher I was creating to watch the pod I want to get deleted. In the watcher I was creating a LabelSelector that was selecting two pods instead of one. This is the complete solution, including the watcher.</p>
<pre><code>func (k *k8sClient) createPodWatcher(ctx context.Context, resName string) (watch.Interface, error) {
    labelSelector := fmt.Sprintf(&quot;app.kubernetes.io/instance=%s&quot;, resName)
    k.logger.Debugf(&quot;Creating watcher for POD with label: %s&quot;, labelSelector)

    opts := metav1.ListOptions{
        TypeMeta:      metav1.TypeMeta{},
        LabelSelector: labelSelector,
        FieldSelector: &quot;&quot;,
    }

    return k.clientset.CoreV1().Pods(k.cfg.Kubernetes.Namespace).Watch(ctx, opts)
}

func (k *k8sClient) waitPodDeleted(ctx context.Context, resName string) error {
    watcher, err := k.createPodWatcher(ctx, resName)
    if err != nil {
        return err
    }

    defer watcher.Stop()

    for {
        select {
        case event := &lt;-watcher.ResultChan():

            if event.Type == watch.Deleted {
                k.logger.Debugf(&quot;The POD \&quot;%s\&quot; is deleted&quot;, resName)

                return nil
            }

        case &lt;-ctx.Done():
            k.logger.Debugf(&quot;Exit from waitPodDeleted for POD \&quot;%s\&quot; because the context is done&quot;, resName)
            return nil
        }
    }
}

func (k *k8sClient) waitPodRunning(ctx context.Context, resName string) error {
    watcher, err := k.createPodWatcher(ctx, resName)
    if err != nil {
        return err
    }

    defer watcher.Stop()

    for {
        select {
        case event := &lt;-watcher.ResultChan():
            pod := event.Object.(*v1.Pod)

            if pod.Status.Phase == v1.PodRunning {
                k.logger.Infof(&quot;The POD \&quot;%s\&quot; is running&quot;, resName)
                return nil
            }

        case &lt;-ctx.Done():
            k.logger.Debugf(&quot;Exit from waitPodRunning for POD \&quot;%s\&quot; because the context is done&quot;, resName)
            return nil
        }
    }
}
