這篇文章主要介紹了Docker遇到Intellij IDEA,Java開發(fā)提升了十倍生產(chǎn)力,本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

一、開發(fā)前準(zhǔn)備

1. Docker的安裝可以參考https://docs.docker.com/install/

2. 配置docker遠(yuǎn)程連接端口

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

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

3. 重啟docker

systemctl daemon-reload
 systemctl restart docker

4.開放端口

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

5.Idea安裝docker插件,重啟

6.連接遠(yuǎn)程docker

(1) 編輯配置

(2) 填遠(yuǎn)程docker地址

(3) 連接成功，會列出遠(yuǎn)程docker容器和鏡像

二、新建項(xiàng)目

創(chuàng)建springboot項(xiàng)目

項(xiàng)目結(jié)構(gòu)圖

(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">

    <relativePath>../pom.xml</relativePath> <!-- lookup parent from repository -->

            </resource>

          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

(2) 在src/main目錄下創(chuàng)建docker目錄，并創(chuàng)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目錄下創(chuàng)建application.properties文件

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

(4) 創(chuàng)建DockerApplication文件

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

(5) 創(chuàng)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
