What tools does the skill use for investigation?

The skill leverages native kubectl commands, network utilities like netshoot, log aggregators, and performance monitoring metrics to provide a 360-degree view of the cluster state.

How does this skill help with CrashLoopBackOff errors?

It utilizes a systematic decision tree to analyze previous container logs, resource limits, and probe configurations to pinpoint the exact application or environment error causing the restart loop.

Can it diagnose internal Kubernetes networking issues?

Yes, it includes specific diagnostic patterns for DNS resolution, service-to-pod mapping, NetworkPolicy restrictions, and CNI-related connectivity problems.

How does it improve incident response times?

By automating the initial data gathering and providing pre-built investigation paths for common SRE scenarios, it significantly reduces the time required for root cause analysis.

Does it support node-level troubleshooting?

It provides deep node health analysis including kubelet status, disk pressure checks, certificate verification, and system resource allocation metrics.

Diagnoses and resolves complex Kubernetes cluster issues across pods, networking, nodes, and control plane components.

소개

The Kubernetes Troubleshooting skill empowers Claude to act as a senior SRE, providing systematic diagnosis and resolution patterns for containerized environments. It features comprehensive decision trees for common failure modes like CrashLoopBackOff and ImagePullBackOff, deep-dive network connectivity analysis, and node-level health checks. Whether dealing with pending pods, DNS resolution failures, or resource-related performance bottlenecks, this skill provides the specific kubectl commands and investigative logic required to reduce Mean Time to Recovery (MTTR) and ensure high availability in production clusters.
