Tekton is a powerful and flexible open-source framework for creating cloud-native Continuous Integration and Continuous Delivery (CI/CD) systems. It provides a set of Kubernetes-style resources for defining and executing CI/CD pipelines, allowing developers to automate the building, testing, and deployment of their applications in a cloud-native manner.

• **Kubernetes-native:** Tekton is built on top of Kubernetes, leveraging its scalability, portability, and resource management capabilities.
• **Declarative Pipelines:** Tekton pipelines are defined using declarative YAML manifests, making them easy to understand, version control, and share.
• **Modularity and Reusability:** Tekton encourages the creation of reusable components called Tasks, which encapsulate specific steps in your CI/CD process. These tasks can be combined into Pipelines to create complex workflows.
• **Flexibility:** Tekton's flexible design allows you to integrate with various tools and services, customizing your pipelines to fit your specific needs.
• **Cloud-Agnostic:** Tekton can be deployed on any Kubernetes cluster, making it suitable for various cloud providers and on-premises environments.

• **Simplified CI/CD:** Tekton simplifies the creation and management of CI/CD pipelines, making it easier to automate the build, test, and deployment process.
• **Scalability:** Tekton leverages Kubernetes's scalability to handle large and complex CI/CD workflows.
• **Portability:** Its cloud-agnostic nature allows you to deploy your pipelines on any Kubernetes cluster.
• **Flexibility:** Tekton's modularity and extensibility enable you to customize your pipelines to fit your specific requirements.
• **Community-Driven:** Tekton is an open-source project with an active community, fostering collaboration and development of new features and integrations.

1. **Task Definition:**

```yaml apiVersion: tekton.dev/v1beta1 kind: Task metadata:

 name: build-image

 steps:
 - name: build
   image: docker:latest
   command: ["docker", "build", "-t", "$(params.image-name)", "."]

This defines a Task named `build-image` that builds a Docker image using the specified `image-name` parameter.

2. **Pipeline Definition:**

```yaml apiVersion: tekton.dev/v1beta1 kind: Pipeline metadata:

 name: my-pipeline

 tasks:
 - name: build
   taskRef:
     name: build-image
   params:
   - name: image-name
     value: my-org/my-app:latest
 - name: deploy
   taskRef:
     name: deploy-app
   runAfter:
   - build

This defines a Pipeline named `my-pipeline` that consists of two tasks: `build` and `deploy`. The `build` task builds a Docker image, and the `deploy` task deploys the image to a Kubernetes cluster.

3. **PipelineRun:**

```yaml apiVersion: tekton.dev/v1beta1 kind: PipelineRun metadata:

 name: my-pipeline-run

 pipelineRef:
   name: my-pipeline

This creates a PipelineRun that executes the `my-pipeline` pipeline.
