一、gitlab-ci原理流程

gitlab-ci是gitlab為持續整合、持續部署提供的一個工具，主要為當利用git客戶端做commit或tag操作提交程式碼時會觸發專案工程根目錄下的.gitlab-ci.yml檔案裡的程式碼shell指令碼，從而實現利用指令碼做具體的做操，細則見http://10.29.139.47/help/ci/quick_start/README。

具體執行流程圖如下：

二、常見java應用gitlab-ci檔案編寫例項：

對於一般的工程CI檔案分為四大步，分別為建立jar包(jarBuild)、建立映象(imageBuild)、將映象推送到映象倉庫(imagePush)和將映象部署到遠端伺服器上(imageProcess)。

stages: #定義整個流程的大步驟

- jarBuild #建立jar包

- imageBuild #建立映象

- imagePush #push到映象倉庫

- imageProcess #映象部署
