Summary

In this chapter, you learned how to use roles to provide abstraction and to help modularizing code for reuse. That's exactly what you see community doing. Creating roles, and sharing them with you. You also learned about include directives, directory layout for roles, and adding role dependencies. We then went on to refactor our code and created a base role, the Nginx role. We also looked at how to manage events and take actions using handlers.

In the next chapter, we will extend the concepts of roles and start adding dynamic data with variables and templates.
