Can this skill help with networking issues?

Yes, it includes diagnostics for service selectors, DNS resolution failures, and Ingress controller configuration issues.

Does it support resource management and scaling?

It provides commands to check resource pressure, view allocated resources per node, and identify pods without defined limits or those exceeding quotas.

Which pod states can this skill help diagnose?

The skill provides specialized workflows for CrashLoopBackOff, ImagePullBackOff, Pending, CreateContainerConfigError, and OOMKilled states.

How does it handle log analysis?

The skill guides users through advanced logging techniques including following previous container logs, time-based filtering, and multi-container output.

Is it compatible with modern Kubernetes features?

Yes, it includes procedures for using ephemeral debug containers (introduced in K8s 1.25) to troubleshoot running pods without sidecars.
