​​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

A well-crafted Dockerfile will avoid the need for privileged containers, unused packages, leaked credentials, or anything that can be used for an attack. We’ll reduce security management and operational overhead by removing known risks in advance. Rather than Dockerfile best practices, we can use Cloud Native Buildpacks to build secure Docker images without needing a Dockerfile.

Cloud Native Buildpacks transform our application source code into secure OCI images that can run on any cloud. They replace Dockerfiles in the app development lifecycle and enable a fast, reproducible build of container images. This chapter configured our CI/CD pipeline to use Cloud Native Buildpacks to build images.
