docs(runbooks): add the vend-failure runbook for the fleet-vend alerts#4
Merged
Conversation
The fleet-vend Grafana alerts (FleetVendReconcileFastBurn/SlowBurn/ProviderAbsent) had no runbook to link — eks-fleet had no docs/runbooks/. Adds vend-failure.md with triage per alert: provider-down/unscraped (ProviderAbsent), and the failing-Workspace drill for the burn alerts — find Workspaces with Synced=False, read the condition message for the real tofu/AWS error (the root cause behind the burn rate), provider log scoping, the budget-burn blast-radius call, and the external-create-pending deadlock recovery (drop the finalizer + direct AWS deletion, never cycle the provider mid-apply), cross-linked to the hub teardown procedure. Closes #3.
CIyamllint + crossplane render passed. |
