牛逼！Docker遇到Intellij IDEA，再次解放了生产力~
链接：https://juejin.im/post/5d026212f265da1b8608828b
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
3. 重启docker
systemctl daemon-reloadsystemctl 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
(1) 配置pom文件
<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>4.0.0modelVersion><groupId>docker-demogroupId><artifactId>com.demoartifactId><version>1.0-SNAPSHOTversion><parent><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starter-parentartifactId><version>2.0.2.RELEASEversion><relativePath />parent><properties><project.build.sourceEncoding>UTF-8project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8project.reporting.outputEncoding><docker.image.prefix>com.demodocker.image.prefix><java.version>1.8java.version>properties><build><plugins><plugin><groupId>org.springframework.bootgroupId><artifactId>spring-boot-maven-pluginartifactId>plugin><plugin><groupId>com.spotifygroupId><artifactId>docker-maven-pluginartifactId><version>1.0.0version><configuration><dockerDirectory>src/main/dockerdockerDirectory><resources><resource><targetPath>/targetPath><directory>${project.build.directory}directory><include>${project.build.finalName}.jarinclude>resource>resources>configuration>plugin><plugin><artifactId>maven-antrun-pluginartifactId><executions><execution><phase>packagephase><configuration><tasks><copy todir="src/main/docker" file="target/${project.artifactId}-${project.version}.${project.packaging}">copy>tasks>configuration><goals><goal>rungoal>goals>execution>executions>plugin>plugins>build><dependencies><dependency><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starter-webartifactId>dependency><dependency><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starter-testartifactId><scope>testscope>dependency><dependency><groupId>log4jgroupId><artifactId>log4jartifactId><version>1.2.17version>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-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
public class DockerApplication {public static void main(String[] args) {SpringApplication.run(DockerApplication.class, args);}}
(5) 创建DockerController文件
public class DockerController {static Log log = LogFactory.getLog(DockerController.class);public String index() {log.info("Hello Docker!");return "Hello Docker!";}}
(6) 增加配置
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]
(7) Maven打包
(8) 运行
(9) 运行成功
(10) 浏览器访问
