Simple Tekton Pipeline - Tekton-pipelines Typing CST Test

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
