Part 3. Docker and DevOps

Now you’re ready to take Docker beyond your development environment and start using it in other phases of software delivery. Build and testing automation are cornerstones of the DevOps movement. We’ll demonstrate Docker’s power through automation of the software delivery lifecycle, deployments, and realistic environment testing. Chapter 6 will show various techniques to deliver and improve continuous integration, making your software deliveries both more reliable and scalable. Continuous delivery is the focus of Chapter 7. We explain what continuous delivery is, and look at ways in which Docker can be used to improve this aspect of your development pipeline. Chapter 8 covers how to harness Docker’s networking model to full effect, creating multi-container services, simulation of realistic networks, and creation of networks on demand. This part takes you from development all the way to the point where you can think about running Docker in production.
