我有一个私人仓库，我有一个 python 包。我已将包包含在我的 requirements.txt 文件中。当我尝试构建 docker 映像时。我收到以下错误

#14 246.0 WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by \'NewConnectionError(\'<pip._vendor.urllib3.connecction.HTTPConnection object at 0x7fe307604520>: Failed to establish a new connection: [Errno -2] Name does not resolve\')\': //pypi-production.vogorental.com/py-commons/

pip 试图访问全局包而不是私有 repo。如何重定向它以使用我的私人仓库

标签： python dockerfile

【解决方案1】：

我正在向您提供我如何在我的项目中使用我的私人包>

FROM python:3.10.6-slim-bullseye
WORKDIR /app
COPY ./downloads /app/downloads
COPY ./my_private_package /app/my_private_package
COPY ./app.py /app/app.py
COPY ./requirements.txt /app/requirements.txt
RUN pip install --no-deps --no-cache-dir -r requirements.txt 
#PORT
EXPOSE 8080
# configure the container to run in an executed manner
ENTRYPOINT [ "python", "app.py" ]

因此，您可以直接将代码复制到 docker 映像并将其作为包导入

from my_private_package import calculate_temprature
