Troubleshooting & Debugging Microservices in Kubernetes
summary
Demo of debugging microservices on Kubernetes that shows concrete steps and tools: inspect deployments with kubectl describe and image sha (don’t use latest), aggregate logs to Stackdriver Logging and export to BigQuery for SQL analysis, use stern/kubetail for live tails, isolate a bad pod by changing labels and use kubectl port-forward and kubectl exec to probe it, and add JVM agent–backed live logs or take snapshots with the debugger to see variables without halting production. The live bug is an empty username in session that bubbles up as 404/500.
