Tekton: Kubernetes-Native CI/CD

by Shriira Press

Tekton is an open-source framework, born in the Continuous Delivery Foundation and widely adopted across the cloud-native ecosystem, for building CI/CD systems that run directly on Kubernetes. This book starts with the problem Tekton solves and its concept model of Steps, Tasks, and Pipelines, and the TaskRun and PipelineRun resources that execute them. It explains how a Task runs inside a pod through the injected entrypoint and sidecar mechanism, how Pipelines form a directed graph with ordering, conditions, and finally tasks, and how Workspaces, Params, and Results move data between pieces. Later chapters cover Tekton Triggers for turning webhooks into runs, Tekton Chains for supply-chain provenance and signing, and the Catalog, Hub, resolvers, and the tkn CLI.
