What Is Jenkins Declarative Pipeline?
Jenkins declarative pipeline uses Groovy Domain Specific Language to define structured pipelines. It uses a set of predefined keywords like pipeline, stages, stage, and steps to write the pipeline code. Here using the state keyword we declare the various stages of a pipeline like fetch, build, test, and deploy. Under the steps block, we write the commands to execute a certain stage. Declarative pipelines are defined in Jenkinsfile which can be stored in the version control system with the application code. This helps the developer team to manage changes, track history, and work more effectively. We can also visualize the build progress of a job written in declarative pipeline syntax. So overall we can say Jenkins’s declarative pipeline simplifies the defining and managing of CI/CD pipelines by offering a simple syntax and structured language.
