the techniques required when moving from asimple setup to a larger deployment. We discussed how to separate your playbookinto multiple parts using includes. We then looked at how we can package up relatedincludes and automatically include them all at once using roles. Finally we discussedpull mode, which allows you to automate the deployment of playbooks on theremote node itself.In the next chapter, we will cover writing your own modules. We start this bybuilding a simple module using bash scri
