Tekton Triggers is a Kubernetes Custom Resource Definition controller that enables event-driven automation by creating Kubernetes resources based on information extracted from event payloads. Written in Go, it extends the Tekton CI/CD framework to allow users to build complete CI/CD systems where all mechanics are defined exclusively through Kubernetes resources. The project originated from a formal design document and integrates tightly with the broader Tekton ecosystem to provide event triggering capabilities for containerized, composable workloads.
The core functionality allows developers to connect external events, such as GitHub push events, directly to Tekton pipeline executions. Rather than requiring separate tooling or manual intervention, Tekton Triggers processes incoming event payloads and automatically instantiates the appropriate Kubernetes resources to trigger CI/CD workflows. This approach enables fully declarative, Kubernetes-native CI/CD systems where event handling is defined through standard Kubernetes CRDs alongside pipeline definitions.
The repository maintains comprehensive documentation including an overview, installation guide, getting started tutorial, and code examples. The getting started guide specifically walks users through setting up an end-to-end image building solution triggered via GitHub push events, providing a practical entry point for new users. Version-specific documentation is available through the releases page and the Tekton website, with Kubernetes version requirements tracked across releases, currently requiring Kubernetes 1.28 or later for the v0.29.x release series.
This interconnection reflects Tekton Triggers' role as a bridge between event sources and pipeline execution within Kubernetes environments.
The project actively welcomes contributions through documented processes in CONTRIBUTING.md and DEVELOPMENT.md files, with designated good first issues and help wanted issues to guide new contributors. The repository is classified across multiple domains including event-driven architecture, orchestration, pipeline triggers, automation, cloud-native technologies, CI/CD, and DevOps tooling, reflecting its comprehensive role in modern containerized deployment workflows.
