Jenkins is an open-source automation server written in Java.
Jenkins helps to automate the non-human part of the software development process, with continuous integration and facilitating technical aspects of continuous delivery.
It supports version control tools, including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, TD/OMS, ClearCase, and RTC, and can execute Apache Ant, Apache Maven, and sbt based projects as well as arbitrary shell scripts and Windows batch commands.

Frequently Asked Questions
Jenkins is typically run as a standalone application in its own process. The Jenkins WAR file bundles Winstone, a Jetty servlet container wrapper, and can be started on any operating system or platform with a version of Java supported by Jenkins.
There are separate requirements for installing Jenkins on Docker, Kubernetes, and other platforms.
Jenkins, an open-source automation server, is widely used for various continuous integration and continuous delivery (CI/CD) tasks. Its flexibility and extensive plugin ecosystem make it suitable for a range of use cases across different industries. Here are common use cases for Jenkins:
Continuous Integration: automated builds, code quality checks, automated testing.
Continuous Delivery and Deployment (CD): deployment automation, environment provisioning, rollback strategies.
Scheduled Jobs and Batch Processing: periodic jobs, batch processing.
Infrastructure as Code (IaC): infrastructure automation, cloud resource management.
Automated Reporting and Notifications: build and deployment notifications, customized reporting.
Cross-Platform Compatibility Testing: multi-platform testing.
Collaboration and Integration: integration with other tools, workflow orchestration.
Automated Documentation Generation: documentation as code.
Several popular alternatives to Jenkins exist, each offering unique features, capabilities, and integrations.

Jenkins differs from other automation servers in several aspects, including its open-source nature, extensibility, flexibility, and the vibrant plugin ecosystem. While the specific features and capabilities can vary among automation servers, here are key differentiators that set Jenkins apart:
Open Source and Extensibility:
Jenkins is an open-source automation server, allowing users to view, modify, and contribute to its source code. Its extensibility is a hallmark feature, with a vast ecosystem of plugins that enable users to customize and extend its functionality.
Jenkins has an extensive plugin ecosystem, with thousands of plugins available for various integrations, tools, and functionalities. Users can install plugins to tailor Jenkins to their specific needs, integrating it with version control systems, build tools, deployment platforms, and more.
Jenkins has a large and active community of users, developers, and contributors. The community provides support, shares best practices, and contributes to the ongoing development and improvement of Jenkins.
Build and Deployment Pipelines:
Jenkins allows users to define complex build and deployment pipelines using the Jenkins Pipeline feature.
Cloud-Native and Kubernetes Integration:
Jenkins has adapted to cloud-native and containerized environments with tools like Jenkins X, designed for Kubernetes and cloud-native applications.
Ease of Use and User Interface:
The user interface of Jenkins has evolved over time, and while it may be perceived as utilitarian, it provides a wide range of features.
Licensing and Cost:
Jenkins is free and open source, making it cost-effective for organizations of all sizes. There are no licensing fees, and users have the freedom to customize and distribute the software.
