Overview of this book

Docker is the de facto standard for containerizing apps, and with an increasing number of software projects migrating to containers, it is crucial for engineers and DevOps teams to understand how to build, deploy, and secure Docker environments effectively. Docker for Developers will help you understand Docker containers from scratch while taking you through best practices and showing you how to address security concerns. Starting with an introduction to Docker, you’ll learn how to use containers and VirtualBox for development. You’ll explore how containers work and develop projects within them after you’ve explored different ways to deploy and run containers. The book will also show you how to use Docker containers in production in both single-host set-ups and in clusters and deploy them using Jenkins, Kubernetes, and Spinnaker. As you advance, you’ll get to grips with monitoring, securing, and scaling Docker using tools such as Prometheus and Grafana. Later, you’ll be able to deploy Docker containers to a variety of environments, including the cloud-native Amazon Elastic Kubernetes Service (Amazon EKS), before finally delving into Docker security concepts and best practices. By the end of the Docker book, you’ll be able to not only work in a container-driven environment confidently but also use Docker for both new and existing projects.

Next steps for taking your DevOps knowledge further

The second section, Running Containers in Production, was geared toward DevOps practices such as continuous integration and continuous deployment (CI/CD), container orchestration with Kubernetes, and monitoring with tools such as Jaeger.

To start with, we looked at options around hosting containers in cloud-based systems and hybrid environments. Next up, we explored the simple option of serving up our application on a single host with Docker Compose. After this, experimenting with Jenkins provided us with our first introduction to CI/CD tools and how these can be used with Docker. With the concept of CD under our belt, it was then on to Chapter 8, Deploying Docker Apps to Kubernetes, which gave us our first taste of Kubernetes for container orchestration. Subsequently, the topic of special container-native cloud deployment options in the form of Spinnaker was then trialed, including understanding what deployment methodologies are...
