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"?>

(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
(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！
