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.

Chapter 2: Containerization with Docker

In the last chapter, we briefly covered containers, the history of containers, and how the technology has redefined the software ecosystem today. We also understood why it is vital for modern DevOps engineers to be familiar with containers and how containers follow config management principles right from the beginning.

In this chapter, we'll get hands-on and explore Docker – the de facto container runtime. By the end of this chapter, you should be able to install and configure Docker, run your first container, and then monitor it. This chapter will also form the basis for the following chapters, as we will use the same setup for the demos later.

In this chapter, we're going to cover the following main topics:

  • Installing tools
  • Installing Docker
  • Introducing Docker storage drivers and volumes
  • Running your first container
  • Docker logging and logging drivers
  • Docker monitoring with Prometheus
  • Declarative...
