The ability to use the code to define the steps of a Continuous Deployment flow gives us more flexibility than we had before with Freestyle jobs. Docker Compose allowed us to run any type of tasks without the need to set up any special infrastructure. Anything can run as long as it is inside a container. Finally, Docker Swarm simplified the Deployment to production-like and production environments considerably. We only scratched the surface of using Jenkins Pipeline to automate our Continuous Deployment flow. There are quite a few improvements we could do. For example, we might use the Pipeline Shared Groovy Libraries Plugin (https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Shared+Groovy+Libraries+Plugin) and move steps, or even whole stages into functions and reduce code repetition. We could also create a Jenkinsfile (https://jenkins.io/doc/book/pipeline/jenkinsfile/) that would move the Pipeline definition from Jenkins into the service repository thus keeping everything related...

Overview of this book
Viktor Farcic's latest book, The DevOps 2.1 Toolkit: Docker Swarm, takes you deeper into one of the major subjects of his international best seller, The DevOps 2.0 Toolkit, and shows you how to successfully integrate Docker Swarm into your DevOps toolset.
Viktor shares with you his expert knowledge in all aspects of building, testing, deploying, and monitoring services inside Docker Swarm clusters. You'll go through all the tools required for running a cluster. You'll travel through the whole process with clusters running locally on a laptop. Once you're confident with that outcome, Viktor shows you how to translate your experience to different hosting providers like AWS, Azure, and DigitalOcean.
Viktor has updated his DevOps 2.0 framework in this book to use the latest and greatest features and techniques introduced in Docker. We'll go through many practices and even more tools. While there will be a lot of theory, this is a hands-on book. You won't be able to complete it by reading it on the metro on your way to work. You'll have to read this book while in front of the computer and get your hands dirty.
