Shipwright: Building Container Images on Kubernetes

by Shriira Press

Shipwright is a CNCF Sandbox framework that turns container image building into a first-class, declarative Kubernetes workload. Instead of running docker build on a laptop, you describe what to build, where to publish it, and which tool should do the work, and the cluster handles the rest. This book walks the whole system: the build problem on Kubernetes, the four resources at the heart of its API (Build, BuildRun, BuildStrategy, and ClusterBuildStrategy), how a BuildRun becomes a running pod through Tekton, the pluggable strategies wrapping Buildah, Cloud Native Buildpacks, Kaniko, BuildKit, ko, and source-to-image, the shp command-line client, the security model, and the practices that make Shipwright dependable in production.
