By: Fabio Alessandro Locati

Overview of this book

Ansible is an open source automation platform that assists organizations with tasks such as application deployment, orchestration, and task automation. With the release of Ansible 2.7, even complex tasks can be handled much more easily than before. Learning Ansible 2.7 will help you take your first steps toward understanding the fundamentals and practical aspects of Ansible by introducing you to topics such as playbooks, modules, and the installation of Linux, Berkeley Software Distribution (BSD), and Windows support. In addition to this, you will focus on various testing strategies, deployment, and orchestration to build on your knowledge. The book will then help you get accustomed to features including cleaner architecture, task blocks, and playbook parsing, which can help you to streamline automation processes. Next, you will learn how to integrate Ansible with cloud platforms such as Amazon Web Services (AWS) before gaining insights into the enterprise versions of Ansible, Ansible Tower and Ansible Galaxy. This will help you to use Ansible to interact with different operating systems and improve your working efficiency. By the end of this book, you will be equipped with the Ansible skills you need to automate complex tasks for your organization.

Provisioning machines in Azure

Lately, Azure is becoming one of the biggest clouds, mainly in some companies.

As you may imagine, Ansible has Azure-specific modules to create Azure environments without pain.

The first thing we will need on Azure, after having created the account, is to set up the authorization.

There are several ways to do it, but the easiest one is probably creating the ~/.azure/credentials file in the INI format containing a [default] section with subscription_id and, alternatively, client_id and secret or ad_user and password.

An example of this would be the following file:

[default]
subscription_id: __AZURE_SUBSCRIPTION_ID__
client_id: __AZURE_CLIENT_ID__
secret: __AZURE_SECRET__

After this, we need a resource group in which we then will create all our resources.

To do so, we can use the azure_rm_resourcegroup, with the following syntax:

    - name: Create resource...
