Idea是Java开发利器，SpringBoot是Java生态中最流行的微服务框架，docker是时下最火的容器技术，那么它们结合在一起会产生什么化学反应呢？

一、开发前准备

1. Docker的安装可以参考https://docs.docker.com/install/

2. 配置docker远程连接端口

vi /usr/lib/systemd/system/docker.service

找到 ExecStart，在最后面添加 -H tcp://0.0.0.0:2375，如下图所示

3. 重启docker

systemctl daemon-reload systemctl restart docker

4.开放端口

firewall-cmd --zone=public --add-port=2375/tcp --permanent

5.Idea安装docker插件,重启

6.连接远程docker

(1) 编辑配置

二、新建项目

创建springboot项目

(1) 配置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 https://maven.apache.org/xsd/maven-4.0.0.xsd'> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.fengqi</groupId> <artifactId>dockerDemo</artifactId> <version>1.0.0</version> <relativePath>../pom.xml</relativePath>  </parent> <groupId>com.fengqi</groupId> <artifactId>web</artifactId> <version>1.0.0</version> <name>web</name> <description>Demo project for Spring Boot</description> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> </dependencies> <build> <plugins> <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin><groupId>com.spotify</groupId><artifactId>docker-maven-plugin</artifactId><version>1.0.0</version><configuration> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources></configuration> </plugin> <plugin><artifactId>maven-antrun-plugin</artifactId><executions> <execution> <phase>package</phase> <configuration> <tasks><copy todir='src/main/docker' file='target/${project.artifactId}-${project.version}.${project.packaging}'></copy> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution></executions> </plugin> </plugins> </build>

(2) 在src/main目录下创建docker目录，并创建Dockerfile文件

FROM openjdk:8-jdk-alpineADD *.jar app.jarENTRYPOINT ['java','-Djava.security.egd=file:/dev/./urandom','-jar','/app.jar']

(3) 在resource目录下创建application.properties文件

logging.config=classpath:logback.xmllogging.path=/home/developer/app/logs/server.port=8990

(4) 创建DockerApplication文件

@SpringBootApplicationpublic class DockerApplication { public static void main(String[] args) { SpringApplication.run(DockerApplication.class, args); }}

(5) 创建DockerController文件

@RestControllerpublic class DockerController { static Log log = LogFactory.getLog(DockerController.class); @RequestMapping('/') public String index() { log.info('Hello Docker!'); return 'Hello Docker!'; }}

(6) 增加配置
