Oftentimes, we will want to perform a single task, but use that single task to iterate over a set of data. For example, you might not want to create one user account but 10. Or you might want to install 15 packages to a system. The possibilities are endless, but the point remains the same—you would not want to write 10 individual Ansible tasks to create 10 user accounts. Fortunately, Ansible supports looping over datasets to ensure that you can perform large scale operations using tightly defined code. In this section, we will explore how to make practical use of loops in your Ansible playbooks.
As ever, we must start with an inventory to work against, and we will use our by-now familiar inventory, which we have ...
