一、准备工作
首先看下各模块pom文件
1、项目父工程POM
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.rd</groupId> <artifactId>dw</artifactId> <version>2.0.0</version> <packaging>pom</packaging> <modules> <module>dw-core</module> <!--核心业务 --> <module>dw-manage</module><!-- 后台 --> <module>dw-api</module><!-- API --> <module>dw-demo</module><!-- demo --> </modules> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> </project>
2、dw-core的POM
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>dw-core</artifactId> <packaging>jar</packaging> <parent> <groupId>com.rd</groupId> <artifactId>dw</artifactId> <version>2.0.0</version> <relativePath>../pom.xml</relativePath> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <relativePath/> </properties> <dependencies> ...... </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <classifier>exec</classifier> </configuration> </plugin> </plugins> </build> </project>
3、dw-demo的pom文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>dw-demo</artifactId> <packaging>jar</packaging> <parent> <groupId>com.rd</groupId> <artifactId>dw</artifactId> <version>2.0.0</version> <relativePath>../pom.xml</relativePath> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> ...... </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <executable>true</executable> </configuration> </plugin> <!-- Docker maven plugin --> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <imageName>${project.groupId}/${project.artifactId}:${project.version}</imageName> <dockerDirectory>src/main/resources/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> <!-- Docker maven plugin --> </plugins> </build> </project>
4、dw-api和dw-manage的pom和dw-demo类似,这里就不展示了
二、创建Dockerfile文件
在dw-demo、dw-api、dw-manage三个模块的sr/main/resources/docker下分别创建Dockerfile文件,Dockerfile 文件用来说明如何来构建镜像。这里以dw-demo为例来说明,文件内容如下:
# 指定基础镜像 FROM hub.c.163.com/library/java # 指定作者名和E-mail MAINTAINER lihua "lh@erongdu.com" #指定挂载点 VOLUME /tmp #将本地文件或目录复制到由dockerfile构建的镜像中 ADD dw-demo-2.0.0.jar demo.jar #设置环境变量 #ENV JAVA_OPTS="" #提供容器运行的默认命令 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom", "-jar", "/demo.jar"]
三、构建打包环境
在服务器上安装jdk、maven 、docker、svn,具体参考如下链接,这里不做赘述。
四、docker部署spring-boot工程
1、进入父工程pom文件所在目录,打包编译,将依赖包放至本地仓库
mvn clean install package -Dmaven.test.skip
2、进入各模块,使用 DockerFile 构建镜像
cd dw-demo mvn package docker:build -Dmaven.test.skip
3、运行该镜像
docker run -p 9882:8082 -t com.rd/dw-demo:2.0.0
五、查看服务
