LINUX-1356A rootless Docker host resolves DNS manually and containers failA rootless container service survives reboot and afterward only name resolution fails while network reachability remains fine.LinuxAdvanced15 minProLINUX-1372A rootless Docker service works until rebootA rootless Docker service works until reboot focuses on Runner Hygiene and asks the reader to isolate the key signal in docker. Rootless failures after reboot often come from XDG runtime path lifecycle drift, not from the...LinuxAdvanced15 minProLINUX-1346A rootless service starts (rootless-service-dns-broke-after-reboot-due-to-user-resolver-path)A rootless service starts (rootless-service-dns-broke-after-reboot-due-to... focuses on dns-resolution and asks the reader to isolate the key signal in Linux. Rootless boot persistence can change which resolver view a process...LinuxAdvanced15 minProLINUX-1320A systemd service sends READY=1 and still fails the first live requestsA service integrates with systemd notifications and later exhibits mysterious first-request failures after clean restarts.LinuxAdvanced15 minProK8S-1335An EKS workload reaches AWS APIs and still fails one secret fetchAn EKS workload reaches AWS APIs and still fails one secret fetch focuses on Identity And Access and asks the reader to isolate the key signal in AWS. Cross-cluster portability often fails at subtle identity defaults rather than at obvio...KubernetesAdvanced15 minProLINUX-1338An Elastic agent starts fine and never enrollsA trust bundle is rotated through symlink swaps and later one long-lived agent still rejects the same endpoint with old TLS errors.LinuxAdvanced15 minProK8S-1317An HPA looks idle (metrics-adapter-cached-old-label-discovery)An HPA looks idle (the key signal) focuses on cluster-maintenance and asks the reader to isolate the key signal in Kubernetes. Visible metrics do not prove the autoscaler is querying them through the same cached path.KubernetesAdvanced15 minProK8S-1323An HPA sees no metrics after a label cleanupA platform team standardizes labels and later an HPA stops seeing metrics even though the backing monitoring query still returns data.KubernetesAdvanced15 minProK8S-1343An OpenSearch operator rollout restarts pods foreverA chart rename seems harmless and later one custom resource keeps failing reconcile with admission or validation errors.KubernetesAdvanced15 minProLINUX-1375MFA is required in policy and one bastion path still bypasses itA bastion hardening change is rolled out and later one login path authenticates users without the expected MFA challenge.LinuxAdvanced15 minProLINUX-1374Split-DNS resolution works on one VPN reconnect and breaks on the nextSplit-DNS resolution works on one VPN reconnect and breaks on the next focuses on incident-response and asks the reader to isolate the key signal in Linux. Modern split-DNS failures often live in per-link resolver priority, not in the tunne...LinuxAdvanced15 minProK8S-1331A Cilium policy rollout looks correct and one namespace still loses trafficA label cleanup is followed by namespace-specific traffic loss that appears only on a subset of nodes.KubernetesAdvanced16 minProK8S-1330A Loki deployment ingests logs correctly and recent queries look inconsistentA Loki deployment ingests logs correctly and recent queries look inconsistent focuses on incident-response and asks the reader to isolate the key signal in grafana. Recent-query inconsistency can be a convergence problem, not immediate...KubernetesAdvanced16 minProCICD-1297A nested package publish with OIDC fails only in the monorepo release jobA monorepo package publishes fine locally and later fails only in the centralized CI release workflow.CI/CDAdvanced16 minProLINUX-1312A rootless Docker service survives restart and published ports vanishA rootless Docker service survives restart and published ports vanish focuses on cluster-bootstrap and asks the reader to isolate the key signal in Linux. Rootless runtime availability and rootless network availability can diverge after re...LinuxAdvanced16 minProLINUX-1307Published Docker ports disappear after firewall reloadA host firewall hardening reload runs cleanly and all container-published ports quietly stop receiving traffic.LinuxAdvanced16 minProK8S-1307The metrics adapter serves custom metrics but the HPA still failsA service rename or chart refactor leaves autoscaling frozen even though direct adapter requests look healthy.KubernetesAdvanced16 minProK8S-1277A node group joins the cluster but DaemonSet pods stay brokenA custom AMI or launch template brings new nodes online and only platform add-ons behave strangely on those instances.KubernetesAdvanced18 minProK8S-1232CoreDNS pods are healthy but one namespace still fails resolutionA hardened namespace loses name resolution after a node-local DNS optimization or add-on change, while the rest of the cluster remains healthy.KubernetesAdvanced18 minProK8S-1243A StatefulSet pod restarts forever after rescheduleA stateful workload reschedules after a node event and later fails repeatedly with permission errors on the data path.KubernetesAdvanced19 minPro
