Docker-Compose 客户端 API 对服务器的调用失败...默认网络服务别名不起作用？

发布于 2025-01-17 08:26:14 字数 810 浏览 0 评论 0原文

我想知道如何解决这个问题！本质上，默认 Docker 网络上通过服务名称进行的动态路由不起作用。 :(

我曾考虑过让它使用静态 IP，但这可能比解决原始问题更多。

docker-compose.yml

version: "3.8"
services:
  client:
    build: client
    ports: [3000]
    depends_on:
      - server
    volumes:
      - ./client:/app

  mongodb:
    image : mongo
    environment:
      - PUID=1000
      - PGID=1000
    ports: [27017]
    restart: unless-stopped
    volumes:
      - ./mongodb/database:/data/db

  server:
    build: server
    ports: [5000]
    restart: always
    depends_on:
      - mongodb
    volumes:
      - ./server:/app

如果我从客户端进行 ping 测试，它将通过浏览器工作

http://0.0.0.0:49246/ping

但是，我真的希望它能够这里的工作方法

http://server:5000/ping

有帮助吗？

I'm wondering how to fix this problem! Essentially the dynamic routing via service name on the default Docker network is not working. :(

I had considered making it use a static IP but that may be more work than fixing the original issue.

docker-compose.yml

version: "3.8"
services:
  client:
    build: client
    ports: [3000]
    depends_on:
      - server
    volumes:
      - ./client:/app

  mongodb:
    image : mongo
    environment:
      - PUID=1000
      - PGID=1000
    ports: [27017]
    restart: unless-stopped
    volumes:
      - ./mongodb/database:/data/db

  server:
    build: server
    ports: [5000]
    restart: always
    depends_on:
      - mongodb
    volumes:
      - ./server:/app

If I do this ping test from the client it will work via the browser

http://0.0.0.0:49246/ping

However, I really want it to work in this approach here

http://server:5000/ping

Help? Thank you!

Web应用程序代码在浏览器中运行，而不是托管文件的服务器。浏览器通常在主机上运行。

听起来您希望服务器映射主机上的已知端口。尝试使用它将主机端口5000映射到服务器容器端口5000 ...

server:
  build: server
  ports:
    - "5000:5000"
  # etc

并在您的Web应用程序代码中连接http：// localhost：5000。

参见 https://docs.docks.docks.docker.com/compose/撰写文件/撰写file-v3/＃ports

如果您要Web应用程序来代理请求（例如，使用创建React App App 代理配置），您将使用内部主机名，因为此操作由此操作执行客户端服务。

"proxy": "http://server:5000"

Web app code runs in the browser, not the server hosting the files. The browser is typically running on the host.

It sounds like you want the server to map a known port on the host. Try using this to map host port 5000 to the server container port 5000...

server:
  build: server
  ports:
    - "5000:5000"
  # etc

and connect on http://localhost:5000 in your web app code.

See https://docs.docker.com/compose/compose-file/compose-file-v3/#ports

If you're wanting your web app to proxy requests (for example using the Create React App proxy configuration), you would use the internal host name since this action is performed by the client service.
