"Progressive Delivery with Flagger for Kubernetes"
"Progressive Delivery with Flagger for Kubernetes" is a comprehensive guide for modern DevOps and SRE professionals seeking to advance their software release strategies on Kubernetes. This book begins by exploring the evolution from traditional CI/CD pipelines to the state-of-the-art practices of progressive delivery, highlighting key concepts such as incremental rollout, risk management, and dynamic feedback loops. Detailed comparisons of deployment strategies—including canary, blue/green, A/B, and shadow releases—equip readers with the knowledge to confidently select and implement the best pattern for their unique requirements, all within the robust, cloud-native landscape.
Building on solid Kubernetes fundamentals, the text delves into the nuanced architectural elements of Flagger, an open-source progressive delivery tool. Readers will learn to master Flagger's integration with leading service meshes and gateways, leverage custom resource definitions for automated deployments, and implement advanced security and observability solutions. The book features practical guidance on cluster preparation, Helm-based installation, complex traffic routing, metrics-driven promotion, rollback automation, and incident response, ensuring operational excellence in both single and multi-cluster environments.
Moving beyond technical implementation, the book addresses the organizational and strategic facets of progressive delivery, including policy enforcement, compliance, cost optimization, and governance for large-scale enterprises. Forward-looking chapters introduce AI/ML-driven deployment automation, chaos engineering, and edge computing use cases, supported by lessons from real-world scenarios and the wider open source ecosystem. Whether you are refining enterprise delivery pipelines or innovating for the next generation of cloud applications, this book is your essential resource for safe, reliable, and rapid software releases with Flagger on Kubernetes.
