IDEA是Java开发利器，Spring Boot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

重启docker

systemctl daemon-reload

systemctl start docker

开放端口

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

Idea安装插件，重启

连接远程docker

1、编辑配置

2、填远程docker地址

3、连接成功，会列出远程docker容器和镜像

二、新建项目

创建Spring Boot项目

1、配置pom文件

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <docker.image.prefix>com.demo</docker.image.prefix>
    <java.version>1.8</java.version>
</properties>
<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.groupId}"/>
						</tasks>
					</configuration>
					<goals>
						<goal>run</goal>
					</goals>
				</execution>
			</executions>
		</plugin>
	</plugins>
</build>
<dependencies>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web</artifactId>
	</dependency>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-test</artifactId>
		<scope>test</scope>
	</dependency>
	<dependency>
		<groupId>log4j</groupId>
		<artifactId>log4j</artifactId>
		<version>1.2.17</version>
	</dependency>
</dependencies>

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

FROM openjdk:8-jdk-alpine ADD *.jar app.jar

ENTRYPOINT ["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.xml 
logging.path=/home/developer/app/logs/
server.port=8990

4、创建DockerApplication文件

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

5、创建DockerController文件

@RestController
public 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
