Summary
In this chapter, we covered how Jinja specifically and uniquely fits within the Ansible world. We learned how Jinja filters work and discovered how these filters can be leveraged within a playbook to provide us with clever playbook implementations. In addition to Jinja filters, we spent time learning how to perform mathematical operations on variables within a Jinja filter context.
In addition to the concept of Jinja filters, we also learned about loops and iterators. These iterators provided us with good insights into iterating over structured data, counting forward and in reverse. We learned also that iterators can be used for iterating through lists (such as the list of fruits that we iterated over in our example). Finally, we learned how to apply Jinja within our playbooks and the specific requirements that surround leveraging Jinja.
In the next chapter, we will cover the Ansible vault. The Ansible vault represents a unique and secure solution for encrypting, storing, and decrypting...
