What methods and tools do you usually use to diagnose and troubleshoot problems in Kubernetes pods?

To diagnose and troubleshoot issues in Kubernetes pods, the following methods and tools are commonly used:

• kubectl describe pod <pod-name> — shows detailed information about the pod, including events and error causes.
• kubectl logs <pod-name> — outputs logs from containers inside the pod, helping understand what is happening inside the application.
• kubectl exec -it <pod-name> -- /bin/sh — allows entering the container for manual inspection and debugging.
• Checking the status of the pod and containers (kubectl get pods, kubectl get events) to identify startup or resource problems.
• Using monitoring and logging tools (Prometheus, Grafana, ELK) for metrics analysis and log review.

These methods help quickly identify causes of failures, such as application errors, network issues, resource shortages, or misconfigurations.
