A practical, in-depth guide to Carvel, the suite of reliable, single-purpose, composable tools for Kubernetes config and delivery. Learn how Carvel applies the Unix philosophy to Kubernetes: the config and packaging problem, the composable toolset, ytt (structure-aware YAML templating and overlays), kbld (image resolution and digest pinning), kapp (application-aware deployment), imgpkg and vendir (bundling and vendoring), kapp-controller (continuous delivery and packaging), operations and workflow (local, CI/CD, GitOps), and Carvel in practice.
