The DevOps 2.1 Toolkit: Docker Swarm

By: Viktor Farcic

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.

If you have your own needs that are not fully covered with Docker or one of the tools in its ecosystem, it is relatively easy to write your own service on top of the API. The truth is that, at the time this chapter was written, the Swarm Mode is only a couple of months old, and there aren’t many third party tools that can be used to fine tune or extend its behavior. Even if you find all the tools that do more or less what you need, it’s still a good idea to write a bit of code yourself and switch from more or less to exactly what you need.

I encourage you to fire up your favorite editor and write a service in your programming language of choice. You can monitor services and send yourself an email whenever a member of your team creates or removes one. Or you can integrate statistics with...
