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.

Sharing your containers on Docker Hub

To share our containers, we'll use Docker Hub and publish the two containers. The rest of the team can pull the pre-built containers from Docker Hub and use them without having to deal with the source code repository at all. They are just microservices to them, just as we don't need the source to Mosca, MongoDB, or Redis with those containers.

Of course, the development team is going to have to run them.

We have created an organization on Docker Hub, dockerfordevelopers, which we will use to publish the containers for this book. You won't be able to push to it, but we can. In order to publish to Docker Hub, you will need to use the docker login command, and you must have already created an account on https://hub.docker.com/.

You can also create your own organization on Docker Hub where you can share your own containers. If you want to use the examples in the GitHub repository for this chapter, you will have to edit the...
