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.

Preface

Managing Docker Containers with Ansible


Ansible provides a unique set of modules that allow Ansible playbook developers to integrate Ansible with Docker directly. The Docker module provides the Ansible playbook developer with the ability to create, start, restart, modify, and remove.

In this section, we will take a look at basic operational techniques that can be applied to managing Docker containers using Ansible. Specifically, we will cover:

  • How to create Docker containers using Ansible
  • How to update Docker containers using Ansible
  • How to delete Docker containers using Ansible
  • How to launch a Docker container using Ansible

Initially, performing these tasks may seem a bit daunting. But once we pull back the veil on this solution, we will see that the implementation of such tasks within a playbook is fairly straightforward. Let's take a look at how these playbook modules can help us manage Docker containers.
