​​Businesses are modernizing and adopting multi-cloud approaches to deliver services. This shift in application deployment has given rise to containerization and Kubernetes for the deployment, management, and scaling of containerized applications. 

This course introduces you to serverless computing and shows you how to build serverless applications using Knative. It teaches CI/CD using Tekton and shows you how to build pipelines triggered by GitHub events. You will create a pipeline that builds container images using Build and, later, Cloud Native Buildpacks. 

In the last part of the course, you will build a web application that integrates with GitHub using a GitHub App, and triggers application build and deployment in response to GitHub events.

Building a Serverless App Platform on Kubernetes

# Summary
This chapter taught us how to use Tekton to build CI/CD pipelines on Kubernetes. We also created Tasks, which are collections of Steps that execute in a particular order. Afterward, we created a Pipeline comprising the `build` and `deploy` Tasks we had created. We saw how to execute them by creating a TaskRun from the Tekton Dashboard and executing a Pipeline using a `pipelinerun` declared in a YAML file and applied using `kubectl`.
