参考抖音：Java不良人 其中的视频演示代码

不推荐把jenkins端口一直开放，推荐使用时候放开（版本不太新，避免漏洞攻击）

[root@VM-4-12-centos soft]# docker-compose -v
Docker Compose version v2.19.1

docker-compose.yml 如下

version: '3.1'
services:jenkins:image: jenkins/jenkins:2.403volumes:- ./data/jenkins/:/var/jenkins_home- /var/run/docker.sock:/var/run/docker.sock- /usr/bin/docker:/usr/bin/docker- /usr/lib/x86_64-linux-gnu/libltdl.so.7:/usr/lib/x86_64-linux-gnu/libltdl.so.7ports:# 8088为访问端口- "8088:8080"# 8081为你要启动的jar服务端口- "8081:8081"expose:- "8080"- "50000"privileged: trueuser: rootrestart: alwayscontainer_name: jenkinsenvironment:JAVA_OPTS: '-Djava.util.logging.config.file=/var/jenkins_home/log.properties' 

找到 docker-compose.yml 下面执行

[root@VM-4-12-centos soft]# docker-compose up -d
查看启动
[root@VM-4-12-centos soft]# docker ps

在浏览器打开Jenkins端口

查找密码

cat /var/lib/jenkins/secrets/initialAdminPassword

添加自己的用户

选择插件

选择“Install suggested plugins”安装默认的插件，下面Jenkins就会自己去下载相关的插件进行安装。

配置Java环境

配置maven环境

wget https://mirrors.aliyun.com/apache/maven/maven-3/3.9.4/binaries/apache-maven-3.9.4-bin.tar.gz#将容器中的文件拷贝出来
sudo docker cp c0cedad006a1:/opt/apache-maven-3.9.4/conf/settings.xml /soft/
#将容器中的文件拷贝回去
sudo docker cp /soft/settings.xml  容器ID:/opt/apache-maven-3.9.4/conf/

修改 maven settings.xml 仓库镜像地址为阿里云镜像（否则下载依赖会很慢）

使用修改maven-settings　阿里云镜像

<mirror><id>alimaven</id><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><mirrorOf>central</mirrorOf>
</mirror>

编写自己代码上gitee

遇到 jar运行报错no main manifest attribute
使用下面代码解决

 <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring-boot.version}</version><configuration><includeSystemScope>true</includeSystemScope><fork>true</fork></configuration><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin>

错误代码如下

   <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring-boot.version}</version><configuration><mainClass>com.example.demo.DemoApplication</mainClass><skip>true</skip></configuration><executions><execution><id>repackage</id><goals><goal>repackage</goal></goals></execution></executions></plugin>

构建后的执行shell命令如下

#!/bin/bash# 获取进程PID
PID=$(ps -ef | grep "demo-0.0.1-SNAPSHOT.jar" |grep -v grep|awk '{print $2}')# 杀死进程
if [ -n "$PID" ]; thenkill -9 $PIDecho "结束进程Process $PID killed" 
elseecho "没有找到指定进程"
fi
cd /var/jenkins_home/workspace/demoss/target
chmod 755 demo-0.0.1-SNAPSHOT.jar 
BUILD_ID=dotkillme nohup java -jar demo-0.0.1-SNAPSHOT.jar &
echo "启动进程"

Gitee + Jenkins 实现自动触发构建
