Docker + Intellij IDEA，提升10倍生產(chǎn)力！

1.Docker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?start?docker??

4.開(kāi)放端口

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

5.Idea安裝插件，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(huì)列出遠(yuǎn)程docker容器和鏡像

二、新建項(xiàng)目

1.創(chuàng)建springboot項(xiàng)目

項(xiàng)目結(jié)構(gòu)圖

1、配置pom文件

??

?????????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"??

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

命令解釋?zhuān)?/strong>

• Image tag : 指定鏡像名稱(chēng)和tag，鏡像名稱(chēng)為 docker-demo，tag為1.1

• Bind ports : 綁定宿主機(jī)端口到容器內(nèi)部端口。格式為[宿主機(jī)端口]:[容器內(nèi)部端口]

• Bind mounts : 將宿主機(jī)目錄掛到到容器內(nèi)部目錄中。

格式為[宿主機(jī)目錄](méi):[容器內(nèi)部目錄](méi)。這個(gè)springboot項(xiàng)目會(huì)將日志打印在容器 /home/developer/app/logs/ 目錄下，將宿主機(jī)目錄掛載到容器內(nèi)部目錄后，那么日志就會(huì)持久化容器外部的宿主機(jī)目錄中。

7、Maven打包

8、運(yùn)行

先pull基礎(chǔ)鏡像，然后再打包鏡像，并將鏡像部署到遠(yuǎn)程docker運(yùn)行

這里我們可以看到鏡像名稱(chēng)為docker-demo:1.1，docker容器為docker-server

9、運(yùn)行成功

10、瀏覽器訪問(wèn)

11、日志查看

自此，通過(guò)IDEA 部署springboot項(xiàng)目到docker成功！難以想象，部署一個(gè)Javaweb項(xiàng)目竟然如此簡(jiǎn)單方便！
