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.

Chapter 5: Alternatives for Deploying and Running Containers in Production

As container technology and cloud computing mature, the number of ways in which you can deploy your Docker containers has exploded. Some of the options are as simple as running Docker on a single host, and others feature advanced features such as autoscaling, multi-cloud support, and more. You could even run your Docker containers on-premises on bare-metal servers or adopt a hybrid cloud solution.

After reading this chapter, you will understand that the many choices available offer different trade-offs. You will learn how to build the smallest viable production environment. You will be able to choose between different cloud providers and their managed container runtimes, as well as articulate the benefits of running Docker either on-premises or in a hybrid cloud. Most importantly, you will be able to make an informed decision about choosing a production path for deploying Docker containers given competing...
