Scripted Pipeline & Declarative Pipeline

Scripted Pipeline

• Pipeline

•

•

• try/catch…

Jenkins 2.0

node(‘has-docker’) { try { checkout scm stage(‘Build’) { sh ‘mvn clean install’ } stage(‘Archive’) { ( ) } if (currentBuild.result == 'SUCCESS') { mail to:"me@example.com", subject:"SUCCESS", body: "passed." } } catch (exc) { mail to:"me@example.com", subject:"FAILURE", body: "failed." } finally { deleteDir() }}

Declarative Pipeline

•

•

• Lint

Jenkins 2.0

pipeline { agent label:’has-docker’, dockerfile: true stages { stage("Build") { steps { sh 'mvn clean install' } } stage("Archive"){ ( ) } } post { always { deleteDir() } success { mail to:"me@example.com", subject:"SUCCESS", body: "passed." } failure { mail to:"me@example.com", subject:"FAILURE", body: "failed." } }}

Pipeline

Declarative Pipeline Examples

Build in Container

// simpleagent { docker “ubuntu:16.04”}

// specify label & argsagent { docker { image “ubuntu:16.04” label “docker-nodes” args “-v /tmp:/tmp -p 8000:8000” }}

Credentials

Credentials

environment { // type: secret text // SECRET_TEXT is defined SECRET_TEXT = credentials(‘SECRET_TEXT')

// type: username and password // SECRET_AUTH_USR and SECRET_AUTH_PSW are defined SECRET_AUTH = credentials('SECRET_AUTH')}

Options

pipeline { options { // 7 buildDiscarder(logRotator(daysToKeepStr: '7')) }}

Triggers

pipeline { triggers { cron('* * * * *') }}

Parallelstage("Commit") { steps { parallel( unitTest: { … }, staticAnalysis: { … }, package: { … } ) }}

Conditions

stage("Production") { when { branch "master" } steps { // deploy to production }}

Stashstage("Archive") { agent { docker “java:8” } steps { sh “gradle jar” stash name: “jar”, includes: “build/libs/*.jar” }}stage(“Deployment”) { agent { docker … } steps { unstash “jar” // jar }}

User Input

stage("Production") { steps { input “Ready to deploy?” }}

Shared Libraries

• GitHub

• Groovy

• https://jenkins.io/doc/book/pipeline/shared-libraries/

Jenkins 2.0

Example: without Library

pipeline {… post { failure { // echo ‘failure!’ with red color ansiColor('xterm') { echo '\033[0;31mFailure!\033[0m' } } }…}

vars/echoErr.groovy

#!/usr/bin/env groovy

def call(String text) { ansiColor('xterm') { echo “\033[0;31m${text}\033[0m" }}

(repository root)+- vars- +- echoErr.groovy

Example: with Library

@Library('miyata-shared-libraries') _pipeline {… post { failure { echoErr ‘Failure!’ } }…}
