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.

Patching processes with Pulp

It is worth mentioning at the outset of this section that Pulp supports two main methods for the distribution of packages from the repositories created within it. The first is a kind of push-based distribution that uses something called the Pulp Consumer.

We will not be exploring this in this chapter for the following reasons:

  • The Pulp Consumer only works with RPM-based repositories and distributions, and at the time of writing, there is no equivalent client available for Ubuntu or Debian. This means that our processes cannot be uniform across the enterprise, which, in an ideal world, they would be.
  • Using the Pulp Consumer means we would have two overlapping means of automation. Distributing packages to nodes using the consumer is a task that can be performed with Ansible, and if we use Ansible for this task, then we have an approach that is common...
