Summary:

Automate the deployment of your environment with the power of the Docker toolchain About This Book Written and reviewed by expert Docker developers The book precisely covers all the essential topics such as building images and managing container swarms required in day to day use for Docker The book includes activities on the docker CLI and exercises such as writing Dockerfiles for Python which will allow you to reinforce the concepts covered Who This Book Is For The book is crafted for developers, system architects, junior and mid-level site reliability engineers interested in adapting a docker workflow. They are also required to have a basic knowledge of UNIX concepts such as ssh, ports and logs What You Will Learn Understand how to effectively design and build containers for different applications Setup an environment for testing, avoiding environment mismatch that is breaking production Setup and manage a multi-tier environment Run, debug, and experiment with applications in a container In Detail DevOps with Docker outlines the power of containerization and the influence this innovation has on development teams and general operations. We also get to understand what DevOps really is, the principles involved and how the process contributes to product health, by implementing a Docker workflow. We will learn to interpret Dockerfile syntax, build images and setup containers and images. In addition, we will deploy a Docker image to the Docker Hub.Docker is an open source containerization tool, that makes it easier to streamline product delivery. It helps reduce the time taken to get from a whiteboard sketch of the business to a money-back implementation. This fast-paced book is a perfect amalgamation of theory and hands-on exercises. The book will take you through the basics of Docker and DevOps and why and how they integrate. You will then understand what containers are, and how to create and manage them. Next, we will work on the docker-compose file and CLI. Then we will move to set up a network with the docker-compose tool. Gradually you will learn how to scale a delivery pipeline and multiple deployments with Docker. Lastly, you will grasp the concept of orchestration and learn to implement the delivery of containerized applications. Style and approach This is a fast-paced, practical hands-on book aimed at experienced developers and system architects. As you progress you'll find helpful tips and tricks, as well as useful self-assessment mater...
