我正在安装Istio的Kubernetes集群上工作，并且我在Pod上使用docker:dind映像来动态构建docker映像。问题是，一旦构建阶段达到我的Dockerfile的RUN pip install numpy，它就会失败并引发以下错误：
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))': /simple/numpy/

用于测试的Dockerfile：
FROM python:3.7.7-slim-buster
RUN pip install numpy
CMD ["echo", "Testing..."]
包含docker:dind映像的容器可以执行以下操作来安装Python软件包：
/ # apk add python3 py3-pip
/ # pip install numpy

可以工作（实际上由于构建依赖项而失败，但是它可以连接到pypi ），但是可以执行以下操作：
/ # cd tmp/
/ # vi Dockerfile # Set the content as described above
/ # docker build .

完全失败...
我想知道是否有人遇到过这样的事情并且能够解决它。
先谢谢了。 ：）
