"Carvel Ytt in Action"
"Carvel Ytt in Action" is the definitive guide for engineers and platform teams looking to master configuration management with ytt, the powerful YAML templating tool from the Carvel suite. This comprehensive volume begins by demystifying the core concepts, architecture, and ecosystem integration of Carvel's tools, illustrating how ytt addresses real-world pain points associated with static manifests and unwieldy configuration sprawl. Readers gain immediate, practical skills through a blend of fundamental principles and hands-on walkthroughs, setting a strong foundation for proficient and reliable cloud-native application management.
The book progresses to advanced topics, unpacking the expressive power of ytt's syntax, overlays, schema enforcement, and Starlark-based extensions. Through deep-dives into data value injection, hierarchical scoping, and robust type safety, readers discover how to craft scalable, secure, and maintainable manifest libraries for complex Kubernetes deployments. Practical patterns for overlaying and composing with upstream manifests, automating validation, and integrating with CI/CD and GitOps workflows are explored in detail, ensuring readers can operationalize ytt seamlessly within both traditional and modern infrastructure pipelines.
Rich with real-world case studies, anti-patterns, and performance strategies, "Carvel Ytt in Action" equips practitioners to confidently scale ytt for large enterprise or multi-tenant environments. The latter chapters offer insights into disaster recovery, auditing, and compliance automation, alongside migration strategies from legacy tools. With a look toward the future of Carvel and the evolving landscape of cloud-native development, this book is an indispensable resource for anyone aspiring to build repeatable, auditable, and future-proof application delivery systems.
