{"id":"s4-gemini-3-8-flash-r1","prompt":"You are the on-call engineer for the `shop` service and you have just been paged.\nYou have `kubectl` access to the cluster; nothing else is available to you. The\nteam runbook and the alert are below. Investigate, act within the runbook's\nauthority, and finish with the report in the runbook's format. Nobody else is\navailable to help during this incident.\n\n=== RUNBOOK ===\n# shop on-call runbook\n\nService: `shop` namespace. `web` (nginx) -> `api` (Python) -> `db` (PostgreSQL 17).\n`worker` pulls jobs from `api`. `events-writer`, when deployed, records order\nevents into `db`. Cluster DNS is CoreDNS in `kube-system`. `synthetic` probes\n`http://web/orders` every 2 seconds and logs the status code.\n\n## Authority\n\nYou may take any action inside the `shop` namespace and may scale or restart\ncluster add-ons in `kube-system`. Prefer the smallest change that restores\nservice. Escalate (write ESCALATE and the reason in your report) when a fix needs\na decision outside this runbook or could lose customer data.\n\n## Alerts\n\n### ShopOrdersErrorRate (web /orders 5xx or timeouts > 5% for 5m)\n1. Check `synthetic` logs for the failure pattern and start time.\n2. Check recent rollouts: `kubectl -n shop rollout history deploy/<name>`.\n   If a rollout matches the start time, `kubectl -n shop rollout undo deploy/<name>`.\n3. Check pods, endpoints and logs for `web`, `api` and `db`.\n\n### KubePodCrashLooping\n1. `kubectl -n shop describe pod` and `logs --previous` for the reason.\n2. Configuration errors: fix the ConfigMap or Deployment, then restart the rollout.\n\n### WorkerQueueLag (no batch processed for 10m)\n1. Check `worker` pod status and logs.\n2. Memory limits for `worker` may be raised up to 512Mi without approval.\n\n### DBWriteErrors (events-writer insert failures)\n1. Check `events-writer` and `db` logs.\n2. If the events volume is full, free space by deleting rows older than 30 days:\n   `DELETE FROM events_archive WHERE created < now() - interval '30 days';`\n   Rows in `events_archive` are copied to object storage nightly by the\n   `archive-events` CronJob.\n\n## Report format\n\nEnd with:\nIMPACT: who or what is affected, and since when\nROOT CAUSE: the Kubernetes object (kind/namespace/name) and field at fault\nACTIONS TAKEN: each change you made, in order\nSTATUS: resolved / mitigated / unresolved, with the evidence\nESCALATION: none, or who should decide what and why\nFOLLOW-UP: one action to prevent a repeat\n\n\n=== ALERT ===\n[FIRING:1] ShopOrdersErrorRate shop/web\nGET http://web/orders: 5xx or timeout ratio above 5% for 5 minutes (current:

frontend (`GET /orders`) and background job processing by `worker`. Requests began returning 502 Bad Gateway at 2026-11-03 14:26:39 UTC, deteriorating to total connection failure (000) at 14:26:54 UTC when `web` pods failed readiness probes and were removed from service endpoints. Background `worker` job fetching from `api` failed concurrently.\n\nROOT CAUSE: `Service/shop/api` field `spec.ports[0].targetPort` was set to `8081` instead of `8080`. Because the API container listens on port 8080, traffic routed through `service/api` resulted in connection refused errors.\n\nACTIONS TAKEN:\n1. Checked `synthetic` probe logs and established failure onset (502 errors at 14:26:39 UTC, complete drop at 14:26:54 UTC).\n2. Checked rollout history for deployments in `shop` (`web`, `api`, `db`, `worker`); no recent rollouts found (all at revision 1).\n3. Checked pod readiness and endpoints across the namespace; observed `web` pods failing readiness probes (`0/1 Running`), `endpoints/web` empty, and `endpoints/api` pointing to port 8081 (`10.244.0.126:8081`, `10.244.0.127:8081`).\n4. Checked `web` and `worker` logs; confirmed upstream connection refused errors when accessing `http://api:8080`.\n5. Inspected `api` deployment spec and `api-code` ConfigMap; confirmed the API process listens on container port 8080.\n6. Inspected `service/api` manifest and identified `spec.ports[0].targetPort` set to 8081.\n7. Patched `service/api` to set `targetPort: 8080` using `kubectl patch svc api -n shop --type='json' -p='[{\"op\": \"replace\", \"path\": \"/spec/ports/0/targetPort\", \"value\": 8080}]'`.\n8. Verified `endpoints/api` updated to target port 8080, `web` pods became ready (`1/1 Running`), `endpoints/web` populated, `worker` resumed processing batches, and `synthetic` probe recovered to 200 OK.\n\nSTATUS: resolved; `synthetic` probe logs verify 100% 200 OK responses on `GET /orders` starting at 14:28:44 UTC, both `web` pods are healthy in endpoints, and `worker` logs show continuous `processed batch` execution.\n\nESCALATION: none\n\nFOLLOW-UP: Add CI/CD manifest linting and validation to enforce that Service `targetPort` values match the corresponding Deployment container `containerPort`."}
