In this chapter, we finally started to pull some of the pieces together and make some fun stuff happen. We learned how much functionality we get by enabling swarm mode, and creating a swarm cluster. And, we found out just how easy it is to set everything up, using one single swarm init command. Then, we learned how to grow and manage our swarm cluster, and finally, we learned how to run our containers as services within our new swarm cluster. It's been fun, right?!

Now, let's take things to the next level. In Chapter 6, Docker Networking, we'll learn about Docker Networking. If you're ready for more good stuff, turn the page.
