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.

Options for Kubernetes local installation

You need to set up a local Kubernetes installation in order to build, package, and test your Docker application in preparation for deploying it to a production installation in the cloud. Please review the Kubernetes Getting Started documentation (https://kubernetes.io/docs/setup/). This documentation calls this local environment a learning environment. Think of the local environment as a way to learn about and test your application before you take the application to production with Kubernetes in the cloud. Let's continue by weighing up the options, starting with Docker Desktop's Kubernetes support.

Docker Desktop with Kubernetes

For most people, this is the easiest way to start experimenting with Kubernetes. You don't have to set up cloud accounts or do a complicated installation to get started if you choose to do this. To install Docker Desktop, follow the download links at https://www.docker.com/products/docker-desktop...
