Click New Item on your Jenkins home page, enter a name for your (pipeline) job, select Pipeline, and click OK. In the Script text area of the configuration screen, enter your pipeline syntax. Check the Use Groovy Sandbox option below the Script text area. A few more ideas to examine are click build now to create the pipeline, or click save.
It represents the continuous delivery and continuous integration of the jobs in the SDLC and Dev. Ops life cycle management in the pipeline. The below diagram shows the Jenkins pipeline. This includes continuous integration and continuous delivery of jobs namely the Build, Deploy, Test, and Release.
What is Jenkins pipeline in continuous delivery space?

A Jenkins project is a repeatable build job which contains steps and post-build actions. The types of actions you can perform in a build step or post-build action are quite limited. There are many standard plugins available within a Jenkins freestyle project to help you overcome this problem.
The most frequent answer is: it consists of a series of steps consisting of build, test, and deploy. Step – It is a single step in the stage, for example, either build or test or deploy from a single step. The first step is to install the build Jenkins plugin pipelines.
Jenkins triggers a build upon every commit to the source code repository, typically to a development branch. Jenkins can be configured to run an initial suite of unit tests to ensure that the commit did not “break the build”. If the tests do not pass, the developer can be immediately notified to take corrective action.
The common practice is that whenever a code commit occurs, a build should be triggered. No minimum requirement. Note that since all builds will be stored on the Jenkins machines, it has to be ensured that sufficient disk space is available for build storage.
