Modern DevOps Practices

By: Gaurav Agarwal

Overview of this book

Containers have entirely changed how developers and end-users see applications as a whole. With this book, you'll learn all about containers, their architecture and benefits, and how to implement them within your development lifecycle. You'll discover how you can transition from the traditional world of virtual machines and adopt modern ways of using DevOps to ship a package of software continuously. Starting with a quick refresher on the core concepts of containers, you'll move on to study the architectural concepts to implement modern ways of application development. You'll cover topics around Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools that will help you to build a base. As you advance, the book covers the core elements of cloud integration (AWS ECS, GKE, and other CaaS services), continuous integration, and continuous delivery (GitHub actions, Jenkins, and Spinnaker) to help you understand the essence of container management and delivery. The later sections of the book will take you through container pipeline security and GitOps (Flux CD and Terraform). By the end of this DevOps book, you'll have learned best practices for automating your development lifecycle and making the most of containers, infrastructure automation, and CaaS, and be ready to develop applications using modern tools and techniques.

Summary

This chapter has covered CI, and you have understood the need for CI and the basic CI workflow for a container application. We then looked at GitHub Actions to build an effective Continous Integration pipeline. We then looked at the Jenkins open source offering and deployed a scalable Jenkins on Kubernetes with Kaniko, setting up a Jenkins master-agent model. We then understood how to use hooks for automating builds, both in the GitHub Actions-based workflow and the Jenkins-based workflow. We then delved into AWS's CI stack using AWS Code Commit and Code Build. Finally, we learned about build performance best practices and dos and don'ts.

By now, you should be familiar with CI and its nuances, along with the various tooling you can use to implement it.

In the next chapter, we will delve into Continuous Deployment/Delivery in the container world.
