*  编写一个controller

@RestController
    public class IndexController {
        
    
        @GetMapping("/index")
        public String index(){
        
            return "success";
        }
    
    }

*  安装Docker插件

*  编写dockerfile

FROM java:8
    
    COPY *.jar /app.jar
    
    CMD ["--server.port=8080"]
    
    EXPOSE 8080
    
    ENTRYPOINT ["java","-jar","/app.jar"]

*  打包服务

*  将jar包和Dockerfile拷贝到/home/myboot目录下

![在这里插入图片描述][20201015085226601.png_pic_center]

*  构建镜像

docker build -f Dockerfile -t demo:1.0 .

*  运行这个镜像，并映射端口

docker run -d -it -p8080:8080 --name demo01 demo:1.0

![在这里插入图片描述][2020101508580797.png_pic_center]

*  访问 虚拟机ip加8080/index
