Part 4. Operations and security

This part of the book focuses on cluster-wide concepts and knowledge you’ll need to effectively manage an OpenShift cluster at scale. These are some of the skills required for any operations team managing OpenShift.

Chapter 9 is all about working with OpenShift’s integrated role-based access control (RBAC). You’ll change the authentication provider for your cluster’s users and work with the system accounts built into OpenShift, along with the default roles for different user types.

Chapter 10 focuses on the software-defined network that’s deployed as part of OpenShift. This is how containers communicate with each other and how service discovery works in an OpenShift cluster.

Finally, chapter 11 brings together the concepts from previous chapters and looks at OpenShift from a security perspective. We’ll discuss how SELinux is used in OpenShift and how you can work with security policies to provide the most effective level of access for your applications.
