2 使用jenkins将项目部署到k8s中

1 前提

　1.1 使用deployment 控制器管理pod

    1.2 项目每次发布前，需要使用git打tag

2  使用jenkins将项目部署到k8s中

以项目admin为例：

admin是一个java项目

创建一个admin的item

          

　　　　

           

c=`mvn dependency:list | grep -i snapshot | grep -v "0.0.1-SNAPSHOT"|| true`
if [ ${c}==""  ];then
  echo -e "33[32m[  可以正常构建  ]33[0m"
else
  echo -e "33[31m[ 服务包含SNAPSHOT，打包失败 !  ]33[0m"
  exit 2
fi
