python - pip在 Alpine docker容器中安装nsenter超时

Question

我正在使用alpine:3.7，我尝试安装python nsenter软件包:

FROM alpine:3.7
MAINTAINER blah-blah <blah@blah.com>

RUN echo "http://dl-2.alpinelinux.org/alpine/v3.7/main" >> /etc/apk/repositories && \
    echo "http://dl-3.alpinelinux.org/alpine/v3.7/main" >> /etc/apk/repositories && \
    echo "http://dl-4.alpinelinux.org/alpine/v3.7/main" >> /etc/apk/repositories && \
    echo "http://dl-5.alpinelinux.org/alpine/v3.7/main" >> /etc/apk/repositories

RUN apk --update --no-cache add python py2-pip docker
RUN pip install --upgrade pip setuptools nsenter

它卡在:

即使我尝试从容器内安装它:

pip install nsenter -vv

我什至尝试从pypi存储库 https://pypi.org/simple/nsenter/中获取nsenter并用于安装:

python setup.py install

README.rst说:

Requires Python 2.6 or higher

但是对于安装，它仅使用python3 / pip3:

Install from PyPI::
sudo pip3 install nsenter

Install from git source::
python3 setup.py install

有什么想法如何安装nsenter而不必更改我的python版本吗？
也许这可能是需要向上游打开的错误？

Answer 1

问题是与基础架构有关!我需要将--mtu = 1450添加到我的docker服务中，因为可能nsenter的某些依赖项需要更大的数据包...
现在它成功运行了!
