Implementing DevOps with Ansible 2

By: Jonathan McAllister

Overview of this book

Thinking about adapting the DevOps culture for your organization using a very simple, yet powerful automation tool, Ansible 2? Then this book is for you! In this book, you will start with the role of Ansible in the DevOps module, which covers fundamental DevOps practices and how Ansible is leveraged by DevOps organizations to implement consistent and simplified configuration management and deployment. You will then move on to the next module, Ansible with DevOps, where you will understand Ansible fundamentals and how Ansible Playbooks can be used for simple configuration management and deployment tasks. After simpler tasks, you will move on to the third module, Ansible Syntax and Playbook Development, where you will learn advanced configuration management implementations, and use Ansible Vault to secure top-secret information in your organization. In this module, you will also learn about popular DevOps tools and the support that Ansible provides for them (MYSQL, NGINX, APACHE and so on). The last module, Scaling Ansible for the enterprise, is where you will integrate Ansible with CI and CD solutions and provision Docker containers using Ansible. By the end of the book you will have learned to use Ansible to leverage your DevOps tasks.

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...
