Systematically diagnose and resolve common GKE issues. This skill provides structured debugging workflows, common causes, and proven solutions for the most frequent problems encountered in production deployments.
Trigger phrases: "pod not starting", "CrashLoopBackOff", "debug GKE issue", "Cloud SQL connection failed", "Pub/Sub not working", "pod pending"
| Running | Pod is executing | Check logs if issues | | Pending | Waiting to be scheduled | Check events, node resources | | CrashLoopBackOff | App crashes repeatedly | Check logs, configuration | | ImagePullBackOff | Can't pull image | Verify image, permissions | | Completed | Pod ran successfully and exited | Normal for batch jobs |
Systematically diagnoses and resolves common GKE issues including pod failures, networking problems, database connection errors, and Pub/Sub issues. Use when pods are stuck in Pending, CrashLoopBackOff, ImagePullBackOff, experiencing DNS failures, Cloud SQL connection timeouts, or Pub/Sub message processing problems. Provides systematic debugging workflows and solution patterns for Spring Boot applications. Source: dawiddutoit/custom-claude.
