About This Book

**Debugging Pods and Logs in Kubernetes: A Practical Guide to Diagnosing Container Issues Using Logs, Events, and CLI Tools** Kubernetes debugging presents unique challenges that distinguish it from traditional application troubleshooting. This comprehensive guide transforms debugging from a reactive, panic-driven activity into a methodical, confidence-building skill set essential for DevOps engineers, developers, and platform engineers working with containerized applications. The book provides systematic approaches to understanding complex, distributed systems through practical examples and real-world scenarios. Readers will master Kubernetes' native debugging tools, primarily kubectl and its powerful subcommands, learning to quickly identify, isolate, and resolve issues in production environments. Starting with fundamental concepts, the guide progresses through essential debugging workflows using kubectl describe, kubectl logs, and kubectl exec. Coverage includes understanding pod lifecycle states, interpreting error messages, implementing log aggregation strategies, and utilizing cutting-edge ephemeral debug containers. Beyond individual tools, the book develops holistic debugging strategies encompassing observability best practices, proactive monitoring, and systematic approaches to complex multi-container debugging scenarios. Each chapter builds upon previous concepts while introducing new techniques, ensuring comprehensive skill development. The practical approach includes real-world debugging scenarios, troubleshooting production outages, and building observability into infrastructure. Special attention is given to debugging init containers, sidecars, and advanced techniques for distributed system diagnostics. Complete with command reference sheets, YAML examples, and setup guides for popular log aggregation tools, this book serves as both learning resource and ongoing reference for Kubernetes practitioners at all levels.
