This document discusses Jenkins best practices, including using plugins to simplify the UI, manage configuration history, rebuild jobs, and mask passwords. It also covers using folders to organize jobs by branch, the job DSL plugin to define jobs programmatically, and artifact repositories to share artifacts between Jenkins instances. More advanced topics include using the multijob plugin for parallel test runs, the pretested integration plugin for branch setup, and integrating pipelines in Jenkins 2.0. The document concludes with bonus techniques like provisioning build slaves with Packer/Vagrant/Docker and load balancing Jenkins slaves.
