我正在使用docker-compose命令来运行多个容器.问题是我的docker-compose必须从公共存储库中提取一些图像,并从私有存储库中提取一些图像.我打算做的是将所有必需的图像推送到私有存储库但是如何使docker-compose从私有存储库中提取图像.

简而言之 - >当图像仅在那里可用时,如何指向私有存储库

我HttpURLConnection用来向使用JAVA Spark创建的本地部署的本地服务发出POST请求.当我使用HttpURLConnection进行POST调用时,我想在请求体中发送一些数据,但每次JAVA Spark中的请求体都为null.以下是我正在使用的代码

Java Spark POST服务处理程序

post("/", (req, res) -> { System.out.println("Request Body: " + req.body()); return "Hello!!!!"; });

HTTPClass进行发布呼叫

`public class HTTPClassExample{
   public static void main(String[] args) {
        try{
            URL url = new URL("http://localhost:4567/");
            HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
            httpCon.setDoOutput(true);
            httpCon.setRequestMethod("POST");
            httpCon.connect();
            OutputStream os = httpCon.getOutputStream();
            OutputStreamWriter osw = new OutputStreamWriter(os, "UTF-8");    
            osw.write("Just Some Text");
            System.out.println(httpCon.getResponseCode());
            System.out.println(httpCon.getResponseMessage());
            osw.flush();
            osw.close();  
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }
}`

我的问题是我有一个docker-compose.yml文件和一个haproxy.cfg文件，我想让docker-compose将haproxy.cfg文件复制到docker容器中。根据Docker composer发布后的复制文件，我可以使用卷来执行此操作，但就我而言，出现以下错误。谁能帮助我实现这一目标。

以下是代码和所有内容

docker-compose.yml

version: "3.3"
services:
 ###After all services are up, we are initializing the gateway
 gateway:
  container_name: gateway-haproxy
  image: haproxy
  volumes:
    - .:/usr/local/etc/haproxy
  ports:
   - 80:80
  network_mode: "host"

命令输出
