Creating a Jenkinsfile. As discussed in the Defining a Pipeline in SCM, a Jenkinsfile is a text file that contains the definition of a Jenkins Pipeline and is checked into source control. Consider the following Pipeline which implements a basic three-stage continuous delivery pipeline.

In respect to this, what is Jenkinsfile written in?

The definition of a Jenkins Pipeline is written into a text file (called a Jenkinsfile ) which in turn can be committed to a project’s source control repository. This is the foundation of “Pipeline-as-code”; treating the CD pipeline a part of the application to be versioned and reviewed like any other code.

What is CI CD pipeline?

What is Jenkins Multibranch pipeline?

Definition from Jenkins : The Multibranch Pipeline project type enables you to implement different Jenkinsfiles for different branches of the same project.

What is Jenkins stash?

stash : Stash some files to be used later in the build

Saves a set of files for later use on any node/workspace in the same Pipeline run.

Subsequently, question is, is Jenkinsfile written in Groovy?
