I am using alpine:3.7 and i try to install python nsenter package:
FROM alpine:3.7

RUN echo "http://dl-2.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
and it is stuck on:

Even if I try to install it from within the container:
pip install nsenter -vv

I even tried to wget the nsenter from pypi repository https://pypi.org/simple/nsenter/ and used to install:
python setup.py install
The README.rst says:
Requires Python 2.6 or higher
But for installation it uses only python3/pip3:
Install from PyPI::
sudo pip3 install nsenter
Install from git source::
python3 setup.py install
Any ideas how to install nsenter without having to change my python version? Maybe this could be a bug that needs to be opened upstream?
The issue was something related to the infrastructure! I needed to add --mtu=1450 to my docker service because probably some dependency from nsenter needed bigger packets... Now it runs successfully!
