Jenkins Pipeline is a suite of plugins that supports implementing and integrating continuous delivery pipelines into Jenkins. It allows developers to define a series of automated steps to build, test, and deploy their code using a simple, human-readable syntax written in Jenkinsfile, a text file checked into the source control repository. Jenkins Pipeline provides robust features such as parallel execution, artifact management, and integration with various other tools and plugins. By using Jenkins Pipeline, teams can automate their CI/CD workflows, ensuring faster and more reliable software delivery.
