Jenkins的精髓是Pipeline(流水線技術),那爲何要用Pipeline呢?實現自動化構建,其中Pipeline可以將之前project中的配置信息以steps的方式放在一個腳本里,將本來獨立運行於單個或者多個節點的任務鏈接起來,實現單個任務難以完成的複雜流程,造成流水式發佈,構建步驟視圖化。python
簡單來講,Pipeline適用的場景更普遍,能勝任更復雜的發佈流程。舉個例子,job構建工做在master節點,自動化測試腳本在slave節點,而不一樣節點的執行處理經過Pipeline能夠。git
【Stage: 階段】,一個Pipeline能夠劃分爲若干個Stage,每一個Stage表明一組操做。注意,Stage是一個邏輯分組的概念,能夠跨多個Node。github
【Node: 節點】,一個Node就是一個Jenkins節點,或者是Master,或者是slave,是執行Step的具體運行期環境。golang
【Step: 步驟】,Step是最基本的操做單元,小到建立一個目錄,大到構建一個Docker鏡像,由各種Jenkins Plugin提供。docker
二者都是pipeline代碼的持久實現,都可以使用pipeline內置的插件或者插件提供的steps,二者均可以利用共享庫擴展。windows
二者不一樣之處在於語法和靈活性。Declarative pipeline對用戶來講,語法更嚴格,有固定的組織結構,更容易生成代碼段,使其成爲用戶更理想的選擇。markdown
可是Scripted pipeline更加靈活,由於Groovy自己只能對結構和語法進行限制,對於更復雜的pipeline來講,用戶能夠根據本身的業務進行靈活的實現和擴展。app
