Learn TEKTON-PIPELINES with Real Code Examples

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.

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

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.)

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

Define reusable Tasks (build, test, deploy)

Define a Pipeline connecting Tasks in order

Parameterize tasks with inputs, outputs, and params

Trigger PipelineRuns via CLI, webhook, or schedule

Monitor TaskRuns and PipelineRuns for success/failure

Beginner: Single-task pipeline for simple build

Intermediate: Multi-task pipeline with params

Advanced: Parallel execution with conditional tasks

Expert: GitOps-style CI/CD with Tekton Triggers

Architect: Enterprise-scale pipelines with caching, secrets, and multi-cluster execution

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

Task - unit of work executed in a Pod

Pipeline - ordered sequence of Tasks

PipelineRun - execution instance of a Pipeline

TaskRun - execution instance of a Task

Resource - input/output for tasks (Git repo, image, etc.)
