Jenkins

Pipeline example

This sample does not use the pipeline declarative syntax to allow non blocking input message.

stage('Build') {
    node {
      checkout scm
        script {
          app = docker.build(config.imageName)
        }
    }
  }
  stage('Test') {
    node {
      script {
        app.inside {
          sh 'echo inside'
        }
      }
    }
  }
  stage('Deployment') {
    timeout(time: 30, unit:'MINUTES') {
      def userInput = input(
          id: 'Proceed1', message: 'Do you want to deploy?', parameters: [
          [$class: 'BooleanParameterDefinition', defaultValue: false, description: '', name: 'Please confirm you agree with deployment']
          ])
        if (userInput == true) {
          milestone()
            node {
              echo 'Deploying...'
            }
        } else {
          echo "Deployment canceled."
        }
    }
  }

Shared libraries

Configuration

First create SSH/User credentials for your private git repository in Credentials > Jenkins > Global Credentials > New Item.

Then in Manage Jenkins > Configure System go to Global pipeline library and add your git repository.

Default version: master (if you want a specific branch)

Save and reload the page to check for errors or successfull message:

Currently maps to revision: beaa49af21b269e3aa0bcc3b5b74d782f4d98ee9

Sample project

Define a vars directory and a MainPipeline.groovy file.

The vars directory are used for global functions.

#!/usr/bin/env groovy

def call(body) {
  def config = [:]
    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = config
    body()

    node {
      echo config.imageName
    }
}

Load library

Jenkinsfile example.

@Library('demopipeline')_

MainPipeline {
  imageName = "demopipeline"
}

If This stage has no steps error is displayed then something went wrong. Check for typo errors when using function libraries.

Groovy syntax

// For loop
list.each { echo it }

// Default map values
def foo = map.bar ?: 'default'
