System Documentation

What problem does it solve?

This Skill helps SREs and DevOps engineers quickly identify and understand the root causes of failures in Kubernetes StatefulSet rollouts and scaling operations.

Core Features & Use Cases

  • Rollout Stuck Diagnosis: Pinpoints why a StatefulSet update is not progressing, whether due to pod issues, update strategy misconfigurations, or partitions.
  • Scaling Failure Analysis: Investigates why scaling up or down operations for a StatefulSet might be blocked.
  • PVC Binding Deadlock Detection: Identifies issues where pods are stuck pending due to PersistentVolumeClaim binding problems.
  • Use Case: A StatefulSet managing a database cluster is stuck during an update, and new pods are not becoming ready. This Skill will analyze the StatefulSet's configuration, pod statuses, and PVC bindings to determine if the issue is with a specific pod's readiness probe, a OnDelete strategy not being followed, or a PVC topology conflict.

Quick Start

Use the statefulset-debug skill to diagnose why the statefulset 'my-db' in the 'production' namespace is not updating.
