Undoubtedly, the trait of testing has been at the forefront of the software engineering discipline. The deep and decisive presence of software in every kind of tangible object in our daily environments these days in order to have plenty of smart, connected, and digitized assets is widely accepted. Also, with an increased focus on distributed and synchronized software, the complexity of the software design, development, testing and debugging, deployment, and delivery are continuously on the rise. Various means and mechanisms are unearthed to simplify and streamline the much-needed automation of software building and the authentication of software reliability, resiliency, and sustainability. Docker is emerging as an extremely flexible tool to test a wide variety of software applications. In this chapter, we will discuss how to effectively leverage the noteworthy advancements of Docker for software...

Overview of this book
Docker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibily and portabily means that you can run apps in the cloud, on virtual machines, or on dedicated servers.
This book will give you a tour of the new features of Docker and help you get started with Docker by building and deploying a simple application. It will walk you through the commands required to manage Docker images and containers. You’ll be shown how to download new images, run containers, list the containers running on the Docker host, and kill them.
You’ll learn how to leverage Docker’s volumes feature to share data between the Docker host and its containers – this data management feature is also useful for persistent data. This book also covers how to orchestrate containers using Docker compose, debug containers, and secure containers using the AppArmor and SELinux security modules.
