1.前言
之前也分享过分离与分层方式部署，本文只不过将之前的那两种方式放到了容器中来部署运行，里面多多少少还是有点坑在里面的，要对简单一点直接使用如下命令部署：
nohup java -jar xxxx.jar --spring.profiles.active=xx ,,,,, > xxxx.log &使用容器部署方式就比这种更高级优雅一点，根据个人喜好去选择适合自己的部署方式。

2.deom项目工程结构
3.分离容器部署
3.1父工程pom
这里只展示build的配置

3.2子模块3的Dockerfile
FROM xxx基础镜像VOLUME /resourcesWORKDIR /appADD target/xxx.jar /app/app.jarADD target/lib /app/lib/ADD target/resources/* /app/resources/# COPY target/resources/*.yml /app/config/ 这种方式是将boostrap.yml文件拷贝到config,提升了加载优先级别，否则找不到这个ymlRUN echo "Asia/Shanghai" > /etc/timezoneEXPOSE xxx对外暴露监听端口ENTRYPOINT java ${JAVA_OPTS} ${JAVA_PARAMETERS} ${SERVER_NAME} -Xss1m -jar /app/app.jar
3.3子模块3的target
子模块3打包之后target下文件如图所示：
3.4构建启动docker命令
#进入到子模块三路劲中docker build -t xx:v2.0.0 .docker run -itd -p xxx:xxx --ip=本机ip(连接wifi的ip) -e JAVA_OPTS="-Xms200m -Xmx200m -Xss256K -Xdebug -Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=jvm远程调试监听端口 -Dfile.encoding=UTF-8" --name xxx-xxxx-server xx:v2.0.0
4.分层容器部署
4.1父工程pom
这里只展示build的配置
<build><plugins><plugin><groupId>org.springframework.bootgroupId><artifactId>spring-boot-maven-pluginartifactId><version>2.3.12.RELEASEversion><configuration><mainClass>xxxlx.xxxx.xxxApplicationmainClass><includeSystemScope>trueincludeSystemScope><layers><enabled>trueenabled>layers>configuration><executions><execution><goals><goal>repackagegoal>goals>execution>executions>plugin><plugin><groupId>org.apache.maven.pluginsgroupId><artifactId>maven-javadoc-pluginartifactId><version>2.9version><configuration><attach>trueattach><charset>UTF-8charset><encoding>UTF-8encoding><docencoding>UTF-8docencoding>configuration><executions><execution><id>attach-javadocsid><goals><goal>jargoal>goals><configuration><additionalparam>-Xdoclint:noneadditionalparam>configuration>execution>executions>plugin><plugin><groupId>org.apache.maven.pluginsgroupId><artifactId>maven-source-pluginartifactId><version>3.2.1version><executions><execution><id>attach-sourcesid><goals><goal>jargoal>goals>execution>executions>plugin><plugin><groupId>org.apache.maven.pluginsgroupId><artifactId>maven-deploy-pluginartifactId><version>2.8.2version><configuration><skip>trueskip>configuration>plugin>plugins><finalName>${project.artifactId}finalName>build>
这个是用之前的分离打包的build改的，测试是ok的
4.2子模块3的Dockerfile
FROM xxxx基础镜像 AS builderVOLUME /resourcesWORKDIR /app# 配置参数ARG JAR_FILE=target/xxxx.jar# 将编译构建得到的jar文件复制到镜像空间中COPY ${JAR_FILE} /app/app.jar#ADD target/lib /app/lib/#ADD target/resources/* /app/resources/# COPY target/resources/*.yml /app/config/# 通过工具spring-boot-jarmode-layertools从application.jar中提取拆分后的构建结果RUN java -Djarmode=layertools -jar app.jar extractRUN echo "Asia/Shanghai" > /etc/timezone# 正式构建镜像FROM xxxx基础镜像WORKDIR /app# 前一阶段从jar中提取除了多个文件，这里分别执行COPY命令复制到镜像空间中，每次COPY都是一个layerCOPY --from=builder /app/dependencies/ ./COPY --from=builder /app/spring-boot-loader/ ./COPY --from=builder /app/snapshot-dependencies/ ./COPY --from=builder /app/application/ ./EXPOSE xxx对外暴露监听端口ENTRYPOINT ["java","-Xms200m","-Xmx200m","-Xss256K","-Xdebug", "-Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=xxxxjvm远程调试监听端口", "-Dfile.encoding=UTF-8", "org.springframework.boot.loader.JarLauncher"]
这种方式是用一个胖jar包来提取分层镜像构建的，缺点是不能动态传递启动参数，必须在ENTRYPOINT中写死。
4.3子模块3的target
这种方式是一个正常的java胖jar包，所有的都打入到这个胖jar中，这里就不展示了。
4.4构建启动docker命令
#进入到子模块三路劲中docker build -t xx:v2.0.0 .docker run -itd -p xxx:xxxx --ip=本机ip(wifi连接的ip) --name lq-invoice-server xx:v2.0.0
5.jekines脚本
pipeline {agent anyenvironment {image_tag="xxxxx/xxxxx/xxxxxx:v1.0.${BUILD_NUMBER}"git_address="http://xxxx/xxxx/xx.git"git_branch="xxx"port=xxxxxgit_auth="xxxxxx"registry_name="xxxxx"registry_pwd="xxxx"container_name="xxxxxxxx"JAVA_OPTS="-javaagent:/agent/skywalking-agent.jar -Dskywalking.agent.service_name=[xxxx-xxxx-xxx] -Dskywalking.trace.ignore_path=/actuator/** -Xms512m -Xmx512m -Xss256K -Xdebug -Xrunjdwp:transport=dt_socket,suspend=n,server=y,address=xxxxxx"}stages {stage("拉取代码") {steps {git branch: "${git_branch}", credentialsId: "${git_auth}",url: "${git_address}"}}stage('质量扫描') {steps {echo '跳过扫描'}}stage('maven编译') {steps {sh 'mvn -B -f ./pom.xml clean install -DskipTests'}}stage('编译镜像') {steps {sh '''cd 子模块三路劲/cp target/*.jar ./docker build -t ${image_tag} .'''sh 'docker login --username=${registry_name} --password=${registry_pwd} xxxx.xxxx.xxxx私服域名'sh 'docker push ${image_tag}'sh 'docker rmi ${image_tag}'}}stage('部署服务') {steps {echo '自动部署'sh '''ssh root@服务器ip << remotesshdocker stop ${container_name}docker rm ${container_name}docker pull ${image_tag}docker run -d -p ${port}:${port} --net=host -e SERVER_PORT=${port} -e JAVA_OPTS="${JAVA_OPTS}" --name ${container_name} ${image_tag}exitremotessh'''}}}}
这个构建分离的是没有啥问题的，构建分层的这个docker run 需要修改一下，参数不能动态传了，直接修改为4.4构建启动docker命令的docker run命令部署即可。
6.总结
这两种方式是之前分享之后的酝酿灵感思路融合实践总结，上面两种方式是互斥的，任选一种即可，希望我的分享对你有所启发和帮助，请一键三连，么么么哒！
