What is Pipeline:
A pipeline is a collection of steps or jobs interlinked in a sequence.
Declarative: Declarative is a more recent and advanced implementation of a pipeline as a code.
Scripted: Scripted was the first and most traditional implementation of the pipeline as a code in Jenkins. It was designed as a general-purpose DSL (Domain Specific Language) built with Groovy.
Why you should have a Pipeline
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 as a part of the application to be versioned and reviewed like any other code.
Creating a Jenkinsfile and committing it to source control provides a number of immediate benefits:
Automatically creates a Pipeline build process for all branches and pull requests.
Code review/iteration on the Pipeline (along with the remaining source code).
