基于gitlab-CI的持续集成与部署

一、gitlab-ci原理流程

gitlab-ci是gitlab为持续集成、持续部署提供的一个工具，主要为当利用git客户端做commit或tag操作提交代码时会触发项目工程根目录下的.gitlab-ci.yml文件里的代码shell脚本，从而实现利用脚本做具体的做操，细则见http://10.29.139.47/help/ci/quick_start/README。

二、常见java应用gitlab-ci文件编写实例：

对于一般的工程CI文件分为四大步，分别为创建jar包(jarBuild)、创建镜像(imageBuild)、将镜像推送到镜像仓库(imagePush)和将镜像部署到远程服务器上(imageProcess)。

stages: #定义整个流程的大步骤

- jarBuild #创建jar包

- imageBuild #创建镜像

- imagePush #push到镜像仓库

- imageProcess #镜像部署

- echo "zhangyitong have existed"

#创建jar包

- mvn clean install -X
