kubernetes - DockerInDocker：在 docker 镜像构建时 pip install 失败

问题描述

我正在开发一个安装了 Istio 的 Kubernetes 集群，并且我正在使用docker:dindpod 上的映像来动态构建 docker 映像。问题是，一旦构建阶段到达RUN pip install numpy我的 Dockerfile ，它就会失败并抛出以下错误：

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/
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))': /simple/numpy/

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))': /simple/numpy/
ERROR: Could not find a version that satisfies the requirement numpy (from versions: none)
ERROR: No matching distribution found for 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图像的 pod 能够安装 Python 包，执行：

/ # apk add python3 py3-pip
/ # pip install numpy

有效（实际上由于构建依赖关系而失败，但它可以连接到 pypi），但执行以下操作：

/ # cd tmp/
/ # vi Dockerfile # Set the content as described above
/ # docker build .

简直失败了……

我想知道是否有人遇到过这样的事情并能够解决它。

提前致谢。:)
