Day 26 - Jenkins Declarative Pipeline

A Pipeline is a collection of steps or jobs interlinked in a sequence. It is a sequence of stages or steps that define the flow of activities involved in building, testing, and deploying software applications. It represents the entire workflow from source code management to production deployment.

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.

pipeline {
    agent any 
    stages {
        stage('Build') { 
            steps {
                // 
            }
        }
        stage('Test') { 
            steps {
                // 
            }
        }
        stage('Deploy') { 
            steps {
                // 
            }
        }
    }
}
