pip在高山docker容器中安裝nsenter超時

Question

我正在使用alpine：3.7，我嘗試安裝python nsenter軟件包：

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：

即使我嘗試從容器內安裝它：

pip install nsenter -vv

我什至嘗試從pypi存儲庫https://pypi.org/simple/nsenter/中獲取nsenter並用於安裝：

python setup.py install

README.rst說：

Requires Python 2.6 or higher

但是對於安裝，它僅使用python3 / pip3：

Install from PyPI::
sudo pip3 install nsenter

Install from git source::
python3 setup.py install

有什么想法如何安裝nsenter而不必更改我的python版本嗎？ 也許這可能是需要向上游打開的錯誤？

Answer 1

問題是與基礎架構有關！ 我需要將--mtu = 1450添加到我的docker服務中，因為可能來自nsenter的某些依賴項需要更大的數據包...現在，它可以成功運行！
