Why is Jenkins used?
Jenkins is a free and open source automation server.
It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery.
It is a server-based system that runs in servlet containers such as Apache Tomcat..
Is Jenkins a CI or CD?
Jenkins is an open source automation server written in Java. It is used to continuously build and test software projects, enabling developers to set up a CI/CD environment. … While Jenkins itself is free, it must be run on a server which will need attention, updates, and maintenance.
What is Jenkins pipeline example?
In simple words, Jenkins Pipeline is a combination of plugins that support the integration and implementation of continuous delivery pipelines using Jenkins. A pipeline has an extensible automation server for creating simple or complex delivery pipelines “as code,” via pipeline DSL (Domain-specific Language).
What are stages in Jenkins pipeline?
Stage. A stage block defines a conceptually distinct subset of tasks performed through the entire Pipeline (e.g. “Build”, “Test” and “Deploy” stages), which is used by many plugins to visualize or present Jenkins Pipeline status/progress.
How do you write a scripted pipeline in Jenkins?
