Hands-On Enterprise Automation on Linux

By: James Freeman

Overview of this book

Automation is paramount if you want to run Linux in your enterprise effectively. It helps you minimize costs by reducing manual operations, ensuring compliance across data centers, and accelerating deployments for your cloud infrastructures. Complete with detailed explanations, practical examples, and self-assessment questions, this book will teach you how to manage your Linux estate and leverage Ansible to achieve effective levels of automation. You'll learn important concepts on standard operating environments that lend themselves to automation, and then build on this knowledge by applying Ansible to achieve standardization throughout your Linux environments. By the end of this Linux automation book, you'll be able to build, deploy, and manage an entire estate of Linux servers with higher reliability and lower overheads than ever before.

Custom Builds with PXE Booting

When working with physical hardware, it is not a given that you could simply clone a virtual machine template to the hard drive and expect it to work. It is, of course, entirely possible to do this with the right tools, but it is tricky, and there is no guarantee the resulting system will run.

For example, cloud-ready images will only have the kernel modules installed for the common virtualized network adapters, and so, may not run (or not have network connectivity) when installed on a modern piece of hardware.

In spite of this, it is still entirely possible to perform automated, standardized builds on physical hardware, and this chapter provides a complete hands-on approach to doing so. In conjunction with the preceding chapter, by the end of this one, you will have practical experience of the automated build process for standardizing images for...
