Overview

Tekton is a cloud-native, continuous integration and delivery (CI/CD) solution for building pipelines. Tekton is a flexible, Kubernetes-native, open-source CI/CD framework that enables automating deployments across multiple platforms (Kubernetes, serverless, VMs, etc) by abstracting away the underlying detail.

Tekton is a standalone project that provides an open, standard and native Kubernetes CI/CD solution.

Main goals:

1. Faster
2. Declarative
3. Reproducible
4. Cloud Native

Tekton Pipeline Benefits

1. Kubernetes native pipelines
2. Runs pipelines in containers
3. Runs server-less
4. Build images with Kubernetes tools
5. Deploy to multiple platforms
6. Developer tools
7. Decoupled

Tekton Concepts

Tekton defines a number of Kubernetes custom resources as building blocks in order to standardize pipeline concepts and provide a terminology that is consistent across CI/CD solutions:

• Step: Smallest unit of execution that defines Kubernetes container spec
• Task: Run commands within container
• Task Run: Runtime representation of an execution of a task
• Pipeline Resources: Acts as input or output to tasks and pipelines. Example, source code, container image, pull request etc.
• Pipeline: Runs tasks in a defined order based on inputs and outputs
• Pipeline Run: Runtime representation of an execution of a pipeline
• Conditions: Conditional tasks in pipeline

Pipeline Workflow

Continuous Integration/Delivery

For Continuous Integration/Delivery we can use triggers and webhooks:

1. Webhook: Send payload to event-listener whenever a push event or a pull request is created. More on webhooks
2. Triggers:
   • Event Listeners: Listen to events over a route
   • Trigger Templates: Template generated PipelineResources & PipelineRun based on event
   • Trigger Bindings: Extract info out of payload to be used in trigger templates
   • Interceptors: Filtration of events and payload
