Understanding roles – the playbook organizer

Roles are designed to enable you to efficiently and effectively reuse Ansible code. They always follow a known structure and often will include sensible default values for variables, error handling, handlers, and so on. Taking our Apache installation example from the previous chapter, we know that this is something that we might want to do over and over again, perhaps with a different configuration file each time, and perhaps with a few other tweaks on a per-server (or per-inventory group) basis.
