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.

Choosing a Kubernetes distribution

So, how do we host Kubernetes beyond installing it on our workstations? When it comes to choosing a Kubernetes distribution, you are presented with a plethora of options, as we saw in Chapter 5, Alternatives for Deploying and Running Containers in Production. We are now going to revisit some of the most popular options to help you gain an understanding of the choices available based on your cloud provider or bare-metal data center setup, as well as see why we are choosing to use EKS to demonstrate the migration of the ShipIt Clicker sample application to Kubernetes.

Google Kubernetes Engine

Google Kubernetes Engine (GKE) is Google's key service for hosting containers in a Kubernetes-based environment. GKE (formerly known as Google Container Engine) was released in an Alpha state in November 2014 and went live in August 2015 for general usage.

It currently offers one of the most mature Kubernetes services offered by cloud providers, including...
