In this Video I am going to show What is Pipeline in Jenkins  (DevOps) and How to create Jenkins Pipeline with an Example. In addition We will also see How to use Pipeline as Code.Jenkins Pipeline is a Whole suite of plugins (10+) which are open-sourced and Shipped with Jenkins 2.x.x.  These Pipeline plugins were Formerly commercially available by CloudBees, called Workflow. We use a file called Jekinsfile to Define pipeline as code (again Groovy DSL) stage("Hello") { echo "*Hello*" } stage("World") { echo "*World*" }

Jenkins sample pipeline script

------------------------

pipeline {

    agent any

    stages {

        stage('Example clean') {

            steps {

                sh "rm -rf my-app"

                sh "git clone https://github.com/pknowledge/my-app.git"

                sh "mvn clean -f my-app"

            }

        }

        stage('Example install') {

            steps {

                sh "mvn install -f my-app"

            }

        }

        stage('Example test') {

            steps {

                sh "mvn test -f my-app"

            }

        }

        stage('Example package') {

            steps {

                sh "mvn package -f my-app"

            }

        }

    }

}

In this Video I am going to show How to use Pipeline script from SCM and How to use Jenkinsfile in Github Project.Jenkins Pipeline is a Whole suite of plugins (10+) which are open-sourced and Shipped with Jenkins 2.x.x.  These Pipeline plugins were Formerly commercially available by CloudBees, called Workflow.

Jenkins sample pipeline script in Jenkinsfile
