Shared Informer Return mostly null values for ADD Pod event #1305

Closed zainjava closed 3 months ago

zainjava commented 8 months ago

Hi Team, I have noticed that when using Shared Informer, when I receive events for Pod Informer I get mostly null values from the K8 API Lib 0.28.2. What am I missing when calling the Shared Informer , Is it a bug in the Informer Lib ? 

func SetupSharedInformer(cluster *K8sCluster,key int) {
    dur := GetCacheInterval()
    cluster.InformerFactory = inform.NewSharedInformerFactory(cluster.ClientSet, dur)
    cluster.InformerFactory.Start(wait.NeverStop)
    k8staConfig.K8sClusters[key].InformerFactory = cluster.InformerFactory
}
podInformer := cluster.InformerFactory.Core().V1().Pods().Informer()
podInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{
    AddFunc: func(obj interface{}) {
        pod := obj.(v1.Object)

        if IsNamespaceOfIngest(cluster, pod.GetNamespace()) {
            AddPod(cluster, pod)
func AddPod(cluster K8sCluster, obj interface{}) {
    VVlog("AddPod")
    pod := obj.(*corev1.Pod)

    var rPod corev1.PodList
    rPod.Items = make([]corev1.Pod, 1)
    rPod.Items[0] = *pod

Attached it the Event Received from the Informer API
