The previous chapter was all about installing Jenkins on various platforms. In this chapter, we will see how to perform some basic Jenkins administration. We will also familiarize ourselves with some of the most common Jenkins tasks, like creating jobs, installing plugins, and performing Jenkins system configurations. We will discuss the following:
Creating a simple Jenkins job with an overview of its components
An overview of the Jenkins home directory
Jenkins backup and restore
Upgrading Jenkins
Managing and configuring plugins
Managing users and permissions
Every small thing that we discuss in the current chapter will form the foundation for the upcoming chapters, where Jenkins will be configured in many ways to achieve Continuous Integration and Continuous Delivery.
