[ci]jenkins构建容器项目

Posted 2020-10-16 毛台

栗子思路说明:

• 不使用任何docker plugin
• 使用jenkins server本地(含mvn环境)构建,无jenkins slave
• jenkins server本地构建的war包,推送deploy机,使用sh动态生成镜像(含镜像名/标签[dev/test]等),并删掉原来的镜像,启动.

jenkins构建容器项目

初始化web节点目录

$ tree /data/dockerfiles/
/data/dockerfiles/
├── first_docker_proj01
│   ├── Dockerfile
│   └── trucks.war
├── scripts
│   └── deploy.sh            # 当执行这个脚本时候,将会将这里的*.war干掉,将最新的war目录下东西移进来.并开始构建镜像
└── war
    └── first_docker_proj01 ## jenkins server构建好后,将war包通过publish over ssh插件推送到这个目录.

系统管理->系统设置->Publish over SSH

新建maven风格的项目

https://github.com/lannyMa/trucks.git

$release_branch

clean package -DskipTests=true

target/*.war
target/
/war/first_docker_proj01
/data/dockerfiles/scripts/deploy.sh first_docker_proj01 hello_docker $release_branch 11000 8080

效果

可以实现一键切换脚本, web节点在启动新容器时候会把老版本容器干掉.

deploy.sh

主要是这个脚本牛x
