Beginning DevOps with Docker

It can be tough to roll out a pre-configured environment if you don't know what you're doing. We'll show you how to streamline your service options with Docker, so that you can scale in an agile, responsive manner. About This Book• Learn how to structure your own Docker containers• Create and manage multiple configuration images• Understand how to scale and deploy bespoke environmentsWho This Book Is ForThis book is ideal for developers, system architects and site reliability engineers (SREs) who wish to adopt a Docker-based workflow for consistency, speed and isolation of system resources within their applications. You'll need to be comfortable working with the command line. What You Will Learn• Learn to design and build containers for different kinds of applications• Create a testing environment to identify issues that may cause production deployments to fail• Discover how you can correctly structure and manage a multi-tier environment• Run, debug, and experiment with example applications in Docker containersIn DetailMaking sure that your application runs across different systems as intended is quickly becoming a standard development requirement. With Docker, you can ensure that what you build will behave the way you expect it to, regardless of where it's deployed. By guiding you through Docker from start to finish (from installation, to the Docker Registry, all the way through to working with Docker Swarms), we'll equip you with the skills you need to migrate your workflow to Docker with complete confidence. Style and approachThis 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 material, exercises and activities to help benchmark your progress and reinforce what you've learned. The activities are devised to simulate the real-world conditions in order to equip you with the necessary skills to accelerate software deployment while still retaining security, portability and saving on costs.
