Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud.

Chapter 15: Automating Workflows with Ansible

If your day-to-day system administration or development work involves tedious and repetitive operations, Ansible could help you run your tasks while saving you precious time. Ansible is a tool for automating software provisioning, configuration management, and application deployment workflows. Initially developed by Michael DeHaan in 2012, Ansible was acquired by Red Hat in 2015 and is now maintained as an open source project.

In this chapter, you'll learn about the fundamental concepts of Ansible, along with a variety of hands-on examples. In particular, we'll explore the following topics:

  • Introducing Ansible
  • Installing Ansible
  • Working with Ansible
