Tekton
kubernetes tasks pipelines and reusable build steps
Why learn Tekton?
Useful for containerized build workflows on Kubernetes. Build credentials and untrusted contributions require strong isolation.
Where it came from
Tekton provides building blocks for CI/CD systems, including tasks, pipelines, and execution resources. Its ecosystem includes triggering and supply-chain-related components.
Build your understanding
Work through these exercises in order. Try the task before opening a reference.
- Define a task with a deterministic output.
- Run the task in a disposable namespace.
- Connect two tasks through a pipeline.
- Inspect logs and results after a failure.
- Restrict credentials available to an untrusted build.

Real World Example
Automated Microservice Build Orchestration
A cloud-native fintech startup managing dozens of independent microservices.
The business problem
Manual build scripts and inconsistent CI environments lead to deployment drift and frequent integration failures during the release cycle.
How this topic solves it
Implementing Tekton Pipelines allows the team to define reusable, version-controlled build steps as Kubernetes custom resources, ensuring that every microservice follows a standardized, immutable build process within the cluster.
- Define individual build steps as Task resources to encapsulate specific logic like unit testing or container image building.
- Compose these Tasks into a Pipeline resource to define the sequential execution order for the microservice build.
- Configure a PipelineRun to trigger the execution of the defined Pipeline against a specific source code repository.
- Utilize the Tekton Catalog to pull pre-verified, reusable Task definitions for common operations like Git cloning or image pushing.
This diagram illustrates the flow from source code to a completed build artifact using Tekton components.

- Source Code → triggers → PipelineRun
- PipelineRun → executes → Pipeline
- Pipeline → invokes → Task
- Task → produces → Artifact
Expected business outcome
Standardized build artifacts and reduced configuration drift across the microservice architecture, leading to more reliable and predictable deployment cycles.
Limitations and checks
Tekton resources are stored as Kubernetes objects, which can lead to cluster state bloat if old PipelineRuns are not pruned; check this by monitoring the count of completed PipelineRun resources in the namespace.
