Docker 遇到 Intellij IDEA 这个插件，再次解放生产力~
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-reload
systemctl start docker4. 开放端口
firewall-cmd --zone=public --add-port=2375/tcp --permanent5. 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>(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
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
