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.

Setting up the Ansible Plugin Development Environment


Ansible plugins, as we mentioned earlier, represent actions that are executed on the master (control server) instead of the target host. These plugins allow us to add additional functionality to the Ansible solution easily. Once the plugin has been written, the action is then available to be called via a traditional YAML playbook action. Before we start coding our action plugin, let's take a look at how to set up the development environment.

Similar to the modules' development environment, action plugins must reside either in ./<type of plugin>_plugins next to the playbook being executed or within one of the specified folders. For example, you might have a directory structure like the following:

#> foo.yml
#> action_plugins/
#> action_plugin/mymodule.py

Or, you may have this:

#> foo.yml
#> callback_plugins/
#> callback_plugin/mymodule.py

Or, you might consider altering the <type of plugin>_plugins path in the...
