我已经使用以下 docker-compose.yml 设置了本地 pypiserver，当我直接使用它时它正在工作

pip install -r requirements.txt --extra-index-url http://127.0.0.1:8082

但是，当我尝试在 Dockerfile 中使用相同的命令时，它不起作用。文件我创建了以下文件：

Dockerfile：

FROM python:3
ENV PYTHONUNBUFFERED=1
ARG PIP_EXTRA_INDEX_URL
WORKDIR /code
COPY requirements.txt /code/
RUN echo "${PIP_EXTRA_INDEX_URL}"
RUN pip install -r requirements.txt $PIP_EXTRA_INDEX_URL
COPY . /code/

码头工人-compose.yml

version: "3.9"

services:
  db:
    image: postgres
    volumes:
      - ./data/db:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
  web:
    build:
      context: .
      args:
        - PIP_EXTRA_INDEX_URL=http://127.0.0.1:8082/simple/
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8800:8000"
    depends_on:
      - db

当我尝试运行docker-compose up 时，出现以下错误：

此代码中是否缺少任何配置？

127.0.0.1 将解析到容器内的容器本身。您必须指定从容器中看到的主机的 IP 地址。

有关如何获取此信息的信息，请参见如何从 docker 容器内部获取 docker 主机的 IP 地址。
