Hands-On Linux Administration on Azure - Second Edition

Overview of this book

Thanks to its flexibility in delivering scalable cloud solutions, Microsoft Azure is a suitable platform for managing all your workloads. You can use it to implement Linux virtual machines and containers, and to create applications in open source languages with open APIs. This Linux administration book first takes you through the fundamentals of Linux and Azure to prepare you for the more advanced Linux features in later chapters. With the help of real-world examples, you’ll learn how to deploy virtual machines (VMs) in Azure, expand their capabilities, and manage them efficiently. You will manage containers and use them to run applications reliably, and in the concluding chapter, you'll explore troubleshooting techniques using a variety of open source tools. By the end of this book, you'll be proficient in administering Linux on Azure and leveraging the tools required for deployment.

Using Ansible

Ansible is minimal in nature, has almost no dependencies, and it doesn't deploy agents to nodes. Only OpenSSH and Python are required for Ansible. It's also highly reliable: changes can be applied multiple times without changing the result beyond the initial application and there shouldn't be any side effects on the rest of the system (unless you write really bad code). There is a strong focus on the reuse of code, which makes it even more reliable.

Ansible doesn't have a very steep learning curve. You can start with just a few lines of code and scale up afterward without breaking anything. In our opinion, if you want to try an orchestration tool, start with Ansible, and if you want to try another, the learning curve will be much less steep.

Installation of Ansible

In Azure Marketplace, a ready-to-go VM is available for Ansible. There are three versions of Ansible available in Azure Marketplace currently: Ansible Instance, Ansible Tower, and...
