Most workloads apply normally, but a webhook policy rejects a specific namespace because labels and defaults diverge. Kubernetes Ingress and Traffic needs to be checked by narrowing scope, re...KubernetesAdvanced28 minProK8S-080Ingress controller leader election lease stayed in the old namespace after a migrationThe new controller deploys cleanly, yet only one replica ever reconciles because the election objects still point at the namespace pattern from the previous release.KubernetesAdvanced18 minProK8S-100Ingress leader election looks healthy but one class still routes nowhereThe controller pods are up, yet routes for one ingress class remain empty because the controller cannot write the status fields other components depend on.KubernetesAdvanced18 minProK8S-052Readiness probe fails only after service mesh sidecar intercepts the health portThe container answers correctly on its native port, but the probe fails because the sidecar path or redirected port does not match the probe expectation.KubernetesAdvanced24 minProK8S-056kube-proxy keeps sending traffic to a deleted backendEndpoints changed correctly, but some nodes still route to a dead backend because stale load-balancing state was not reconciled as expected.KubernetesAdvanced26 minProK8S-022Service endpoint count drops during rolling updateService endpoint count drops (Rollout Stuck) is a hands-on troubleshooting drill. Pods are healthy one by one, but the endpoint pool shrinks too far during rollout and causes short traffic gaps. Kubernetes Ingress and Traffic needs to be checked by narrowing scope, recent chan...KubernetesIntermediate23 minProK8S-1700A Cilium policy is correct and one DNS path still failsA DNS path still fails from one workload even after the Cilium policy was corrected.KubernetesIntermediate11 minProK8S-1790A mesh route is healthy and one client still failsOne client still fails even though the mesh route is healthy.KubernetesIntermediate11 minPro
