Tekton-pipelines Language Guide

Tekton Pipelines is an open-source Kubernetes-native framework for creating CI/CD systems. It defines pipelines as Kubernetes custom resources that describe tasks, dependencies, and workflow orchestration.

Primary Use Cases

  • ▸Kubernetes-native CI/CD pipelines
  • ▸Automated build, test, and deploy workflows
  • ▸Reusable and composable Tasks for multiple pipelines
  • ▸Parallel and conditional task execution
  • ▸Integration with GitOps and container registries

Notable Features

  • ▸Kubernetes-native CRDs for pipelines, tasks, and resources
  • ▸Reusable Tasks and Pipelines for modular workflows
  • ▸Flexible parametrization and variable substitution
  • ▸PipelineRuns and TaskRuns for execution tracking
  • ▸Integration with GitHub, GitLab, and container registries

Origin & Creator

Created by the Continuous Delivery Foundation (CDF) in 2018 to standardize CI/CD on Kubernetes.

Industrial Note

Widely used in cloud-native environments, Kubernetes-native DevOps, GitOps workflows, automated testing, and continuous delivery of microservices.

Quick Explain

  • ▸Tekton Pipelines enables CI/CD pipelines as Kubernetes-native resources.
  • ▸Uses declarative YAML manifests for pipelines, tasks, and resources.
  • ▸Supports modular, reusable Tasks and Pipelines.
  • ▸Runs on Kubernetes clusters using Tekton Controllers and Pods.
  • ▸Facilitates parallel and sequential execution of tasks with dependency management.

Core Features

  • ▸Pipeline - ordered sequence of Tasks
  • ▸Task - reusable unit of work
  • ▸PipelineRun - execution instance of a Pipeline
  • ▸TaskRun - execution instance of a Task
  • ▸Resources and Params - inputs, outputs, and parameters for tasks

Learning Path

  • ▸Learn Kubernetes basics
  • ▸Understand Tekton CRDs (Pipeline, Task, PipelineRun)
  • ▸Write basic Task and Pipeline YAML manifests
  • ▸Use Tekton CLI to manage pipelines
  • ▸Integrate pipelines with triggers and container registries

Practical Examples

  • ▸Build Docker image and push to registry
  • ▸Run unit tests for a microservice
  • ▸Deploy application to Kubernetes staging environment
  • ▸Trigger pipelines on GitHub webhook events
  • ▸Run parallel integration tests with multiple TaskRuns

Comparisons

  • ▸Tekton vs GitLab CI: Kubernetes-native vs GitLab-hosted CI/CD
  • ▸Tekton vs Jenkins X: Kubernetes-native, CRD-driven pipelines vs opinionated workflows
  • ▸Tekton vs Argo Workflows: Tekton focused on CI/CD, Argo on general workflows
  • ▸Tekton vs Jenkins: Declarative pipelines vs plugin-driven
  • ▸Tekton vs GitHub Actions: Kubernetes-native vs GitHub-hosted runners

Strengths

  • ▸Native Kubernetes integration for scaling and orchestration
  • ▸Highly modular and reusable workflow components
  • ▸Supports CI/CD best practices like artifacts, caching, and triggers
  • ▸Parallel task execution and dependency management
  • ▸Strong ecosystem with Tekton Triggers, Chains, and Dashboard

Limitations

  • ▸Requires Kubernetes cluster to run
  • ▸Steeper learning curve than traditional CI/CD tools
  • ▸Debugging pipelines can be complex for beginners
  • ▸Limited UI for visual pipeline editing (mostly CLI/manifest-driven)
  • ▸Some integrations require additional Tekton extensions or tools

When NOT to Use

  • ▸Non-Kubernetes environments
  • ▸Small-scale projects without CI/CD complexity
  • ▸Teams unfamiliar with Kubernetes
  • ▸Rapid prototyping without cluster setup
  • ▸Projects requiring non-containerized CI/CD

Cheat Sheet

  • ▸tkn pipeline list
  • ▸tkn pipeline describe <pipeline-name>
  • ▸tkn pipeline start <pipeline-name>
  • ▸kubectl get pipelinerun
  • ▸kubectl logs <pod-name>

FAQ

  • ▸Can Tekton run outside Kubernetes? -> No, it's Kubernetes-native.
  • ▸Do I need Docker images for tasks? -> Yes, tasks run in containerized Pods.
  • ▸Can tasks run in parallel? -> Yes, via dependencies in the Pipeline.
  • ▸Is Tekton free? -> Yes, open-source under Apache 2.0.
  • ▸Can Tekton pipelines integrate with GitOps? -> Yes, triggers can automate deployments.

30-Day Skill Plan

  • ▸Week 1: Create and run single Task
  • ▸Week 2: Build multi-Task Pipeline
  • ▸Week 3: Parameterize tasks and pipeline
  • ▸Week 4: Use Tekton Triggers for webhook automation
  • ▸Week 5: Implement caching, secrets, and production-grade pipelines

Final Summary

  • ▸Tekton Pipelines provide Kubernetes-native CI/CD capabilities.
  • ▸Workflows are defined declaratively via YAML CRDs.
  • ▸Supports modular, reusable tasks with parameterization.
  • ▸Enables event-driven pipelines with triggers.
  • ▸Ideal for cloud-native, containerized CI/CD and GitOps workflows.

Project Structure

  • ▸tasks/ - YAML manifests for Tasks
  • ▸pipelines/ - YAML manifests for Pipelines
  • ▸triggers/ - YAML manifests for event-based triggers
  • ▸scripts/ - optional shell or scripts executed in tasks
  • ▸resources/ - definitions for inputs, outputs, and secrets

Basic Concepts

  • ▸Task - smallest unit of execution
  • ▸Pipeline - sequence of Tasks
  • ▸PipelineRun - execution of a Pipeline
  • ▸TaskRun - execution of a Task
  • ▸Resources - inputs/outputs for pipelines (Git repos, images, etc.)
