Tekton Pipelines in Kubernetes

1. Introduction

Tekton is an open-source framework for creating CI/CD systems. It provides Kubernetes-native components that enable you to define, run, and manage pipelines.

2. Key Concepts

3. Installation

To install Tekton Pipelines, you can use the following command:

kubectl apply -f https://github.com/tektoncd/pipeline/releases/latest/download/release.yaml

Verify the installation by checking the Tekton pipeline pods:

kubectl get pods -n tekton-pipelines

4. Creating Pipelines

Step-by-Step Process

1. Create a Task that defines what actions should be performed.
2. Create a Pipeline that references the tasks in the desired order.
3. Run the pipeline using a PipelineRun.

Example of a Simple Pipeline

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: build
spec:
  steps:
    - name: build
      image: docker
      script: |
        docker build -t my-image .
---
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
  name: my-pipeline
spec:
  tasks:
    - name: build-task
      taskRef:
        name: build
---
apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: my-pipeline-run
spec:
  pipelineRef:
    name: my-pipeline

5. Best Practices

• Keep your tasks modular.
• Use parameters to make tasks reusable.
• Monitor and log pipeline runs for better debugging.
