1. Jenkins Pipeline 簡介 qrtt1 Ҟᑺ
2. 什麼是 Pipeline • Delivery Pipeline (from Continuous Delivery) • Jenkins Workflow Plugins • Job Workflow Pipeline • Pipeline 由多個 Step 組成，並且⽀支援 Pause/Resume • Pipeline 內的狀態必需可序列化 (Serializable) • 或宣告為不必列⼊入狀態 @NonCPS 的 function
3. 為什麼是 Pipeline • 依然是 Jenkins Job 的⼀一種，依然很 FreeStyle。 • 為的是 Pipeline as Code • 它是 groovy DSL (domain specific language) و͉છՓ ˢ FreeStyle һ FreeStyle
4. Pipeline DSL • Jenkins 的 Pipeline 介紹
 https://jenkins.io/solutions/pipeline/ • Pipeline 寫作教學

5. 建⽴立 Pipeline Job • Pipeline Script from in-place editor • Pipeline Script from SCM • Multi-branch Pipeline (from SCM) પᑥԴ͜

6. 建⽴立 Pipeline 的⽅方式 • Pipeline Script Editor
7. 建⽴立 Pipeline 的⽅方式 • Pipeline Script from SCM
8. Pipeline 規劃 SCM Checkout War Build Test SCM Commit Deploy Release
9. Pipeline Script DEMO/Overview
10. Steps: node, stage, echo node { stage ('checkout') { echo 'checkout from git' } stage ('build') { echo 'build' } // … skip … } ίࡳɓ̨ዚኜൺ ࡳɓࡈචݬ ਂԬʡჿ
11. Steps: git stage ('checkout') { echo 'checkout from git' git url: 'https://my-scm/path/my-project.git' branch: 'master' } optional
12. Steps: dir, pwd, sh (bat) dir ('project') { pwd() stage ('build') { sh """gradle clean build""" } stage ('test') { sh """gradle check""" } // … skip … }
13. Steps: step, archiveArtifacts stage ('archive') { step([$class: 'ArtifactArchiver', 
 artifacts: "build/**/*.war", 
 fingerprint: true]) } stage ('archive') { archiveArtifacts 
 artifacts: "build/**/*.war", 
 fingerprint: true } ᔚٙᄳج อٙᄳج requires Jenkins 2.2+ with newer plugins
14. Refactoring Pipeline • 使⽤用 Function 合併多個 steps 為⼀一個有意義的動作 • 實作新的 Pipeline Step • 使⽤用 Pipeline Shared Libraries Ыဵə෗k ೌج༨

15. Pipeline Shared Library • 使⽤用⽅方法 • 啟⽤用 Jenkins ssh (因為 Jenkins 內建的 git repo ⺫⽬目前僅能 ssh auth) • 安裝 Plugin (id: workflow-cps-global-lib) • 使⽤用 git 指令 commit & push 提交 Shared Library 並在 Pipeline Script 開始使⽤用 https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+SSH XFC

16. Pipeline 使⽤用⼼心得 • Pipeline as Code 可以⽅方便版本管理 • 內建的 Pipeline Step 不夠多，得常得依賴 sh 或 bat 呼叫外部指令。 • 間接使⽤用 DevOps Tool 處理 • Ansible, Chef, Puppet • Ant, Maven, Gradle
