From Jenkins Documentation:
Jenkins is a self-contained, open source automation server which can be used to automate all sorts of tasks such as building, testing, and deploying software. Jenkins can be installed through native system packages, Docker, or even run standalone by any machine with the Java Runtime Environment installed.
Jenkins is one of the more popular systems for continuous integration and many jenkins-plugins are available that extend the out-of-the-box functionality. Jenkins is actually a fork of the hudson product and was created because the developers feared a dispute with Oracle about the Hudson trademark.
Usage:
Use this tag for questions about Jenkins in general, or about using Jenkins for tasks like building, testing and deploying software. For questions specifically about writing or using 3rd party Jenkins plugins, please use the jenkins-plugins tag.
