Learn, develop and hone your Linux and DevOps skills by building a lab for learning, testing and exploring the latest Linux and open-source technologies. This book helps Linux users and others to master modern DevOps practices using a wide range of software and tools.

Having a home or work-based Linux lab is indispensable to anyone looking to experiment with the ever-evolving landscape of new software and DevOps. With open-source tools and readily available hardware, you will end up with a lab you can use to try virtually any modern software, including Chef, Docker, Kubernetes and stalwarts like DNS, Dovecot, and Postfix for email. You'll  set up pipelines for software deployment and focus on discrete projects that help you learn through doing. In the end, you'll acquire the skills needed to become better informed, more marketable engineers and developers, and better able to take on a wide array of software projects with confidence.

Practical Linux DevOps is the perfect companion for those who want to learn how to build systems with utility and learn about modern hardware and software practices.

You will:

• Set up a Linux-based virtualization environment and workstation
• Create a lab network with a fully qualified domain
• Build web-based applications with NGINX and LAMP
  
• Use version-control tools like Git
• Automate deployments and configurations
  
• Think like a modern DevOps engineer
