Pipeline Syntax

The Pipeline Syntax has two forms (https://jenkins.io/doc/book/pipeline/syntax/#declarative-pipeline):

• Declarative Pipeline
• Scripted Pipeline

The difference between the two forms is that the Declarative Pipeline syntax is meant to be a simpler syntax than the Scripted Pipeline. The Scripted Pipeline syntax is a DSL, that follows the Groovy programming language semantics.

Here we have the actual Pipeline Syntax that the pipeline editor created for us. It is using the Declarative Pipeline syntax and there are several items to discuss in this syntax:

      args '-v /Users/jean-marcelbelmont/jenkins_data'
      image 'node:10-alpine'

  }
  stages {
