Learning Ansible 2.7 - Third Edition

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.

Building compiled software with RPM packaging

RPM packaging is very useful for non-binary applications and close to a necessity for binary applications. This is also true because the difference in complexity is pretty low between a non-binary and a binary case. In fact, the build and the installation will work in exactly the same way. The only thing that will change is the SPEC file.

Let's look at the SPEC file that's needed to compile and package a simple Hello World! application written in C:

%global commit0 7c288b9d80a6ef525c0cca8a744b32e018eaa386 
%global shortcommit0 %(c=%{commit0}; echo ${c:0:7})
