In Chapter 8, Enterprise Repository Management with Pulp, we explored the Pulp software package and how it lends itself to automated, repeatable, controllable patching in an enterprise setting. In this chapter, we will build on this by taking a look at a product called Katello, which is complementary to Pulp and lends itself to not just patching but complete infrastructure management.

Katello is a GUI-driven tool that provides advanced solutions for enterprise infrastructure management, and in many ways can be considered to be the successor to the venerable Spacewalk product that many are familiar with. We will explore why you would choose Katello for this purpose and then proceed with hands-on examples of how to build a Katello server and perform patching.

The following topics will specifically be covered in this chapter:

• Introduction to Katello
• Installing a Katello server
• Patching with Katello
