Enhance your software deployment workflow using containers Key Features • ●Get up-and-running with basic to advanced concepts of Docker • ●Get acquainted with concepts such as Docker containers, Docker images, orchestrators and so on. • ●Practical test-based approach to learning a prominent containerization tool Book Description Docker containers have revolutionized the software supply chain in small and big enterprises. Never before has a new technology so rapidly penetrated the top 500 enterprises worldwide. Companies that embrace containers and containerize their traditional mission-critical applications have reported savings of at least 50% in total maintenance cost and a reduction of 90% (or more) of the time required to deploy new versions of those applications. Furthermore they are benefitting from increased security just by using containers as opposed to running applications outside containers.

This book starts from scratch, introducing you to Docker fundamentals and setting up an environment to work with it. Then we delve into concepts such as Docker containers, Docker images, Docker Compose, and so on. We will also cover the concepts of deployment, orchestration, networking, and security. Furthermore, we explain Docker functionalities on public clouds such as AWS.

By the end of this book, you will have hands-on experience working with Docker containers and orchestrators such as SwarmKit and Kubernetes. What you will learn • ●Containerize your traditional or microservice-based application • ●Share or ship your application as an immutable container image • ●Build a Docker swarm and a Kubernetes cluster in the cloud • ●Run a highly distributed application using Docker Swarm or Kubernetes • ●Update or rollback a distributed application with zero downtime • ●Secure your applications via encapsulation, networks, and secrets • ●Know your options when deploying your containerized app into the cloud Who this book is for This book is targeted at system administrators, operations engineers, DevOps engineers, and developers or stakeholders who are interested in getting started with Docker from scratch.
