Dockerfile中的pip和docker-compose怎么用？

Question

我正在尝试使用 docker-compose.yml 文件构建 python 应用程序的 docker 图像。 但是在使用 pip 安装依赖项时出现错误。 这是我的 docker-compose 文件：

version: '3.8'

services:
  scaleway:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - ./pur_beurre/:/usr/src/pur_beurre/
    ports:
      - 8000:8000
    env_file:
      - ./.env.dev

我的 Dockerfile：

# pull official base image
FROM python:3.8-alpine

# set work directory
WORKDIR /pur_beurre

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt

# copy project
COPY . .

# collect static files
RUN python manage.py collectstatic --noinput

# add and run as non-root user
RUN adduser -D myuser
USER myuser

# run gunicorn
CMD gunicorn pur_beurre.wsgi:application --bind 0.0.0.0:$PORT

我的错误是：

我试图从 Dockerfile 中删除命令RUN pip install --upgrade pip pip 但随后出现此错误：

Answer 1

从错误看来，您需要提供系统的架构。

您可以向 docker build（甚至 docker-compose）提供--platform选项来定义要为其构建映像的目标平台。

在您的情况下，在构建图像时：

docker build --platform windows/amd64  .

您也可以在FROM语句中提供

FROM --platform=windows/amd64 python:3.8-alpine

Answer 2

尝试使用以下内容创建文件pip.conf<\/code>并将其放入您的图像中

点子配置文件<\/strong>

[global]
timeout = 60
index-url = https://pypi.python.org/simple
trusted-host = pypi.python.org
