Preface

Summary


In this chapter, we have seen a large number of concepts that will help scale your infrastructure beyond the single node. We started with inventories files used to instruct Ansible about our machines, then how to have host-specific and group-specific variables while running the same command on multiple heterogeneous hosts. We then moved on to dynamics inventories that are populated directly by some other system (usually a cloud provider). In the end, we analyzed multiple kinds of iteration in the Ansible playbooks.

In the next chapter, we will structure our Ansible files in a saner way to ensure maximum readability. To do this, we introduce roles which simplify the management of complex environments even more .
