当 Docker 遇上 IDEA ，生产力彻底炸裂了
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?start?docker?4.开放端口
firewall-cmd?--zone=public?--add-port=2375/tcp?--permanent?5.Idea安装插件,重启
6.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
1.创建springboot项目
项目结构图
(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?http://maven.apache.org/xsd/maven-4.0.0.xsd">??<modelVersion>4.0.0</modelVersion>??<groupId>docker-demo</groupId>??<artifactId>com.demo</artifactId>??<version>1.0-SNAPSHOT</version>??<parent>??<groupId>org.springframework.boot</groupId>??<artifactId>spring-boot-starter-parent</artifactId>??<version>2.0.2.RELEASE</version>??<relativePath?/>??</parent>??<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.version}.${project.packaging}"></copy>??</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>??</project>?(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
命令解释
Image?tag?:?指定镜像名称和tag，镜像名称为?docker-demo，tag为1.1??Bind?ports?:?绑定宿主机端口到容器内部端口。格式为[宿主机端口]:[容器内部端口]??Bind?mounts?:?将宿主机目录挂到到容器内部目录中。格式为[宿主机目录]:[容器内部目录]。这个springboot项目会将日志打印在容器??/home/developer/app/logs/?目录下，将宿主机目录挂载到容器内部目录后，那么日志就会持久化容器外部的宿主机目录中。?(7) Maven打包
(8) 运行
先pull基础镜像，然后再打包镜像，并将镜像部署到远程docker运行
这里我们可以看到镜像名称为docker-demo:1.1，docker容器为docker-server
(9) 运行成功
(10) 浏览器访问
(11) 日志查看
自此通过idea 部署springboot项目到docker成功！难以想象，部署一个Javaweb项目竟然如此简单方便！
