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.
