*** uWSGI compiling server core ***
Any idea what could cause this? I'm installing the following dependencies beforehand:
RUN apk --update add \
bash \
python \
python-dev \
py-pip \
gcc \
zlib-dev \
git \
linux-headers \
build-base \
musl \
musl-dev \
memcached \
libmemcached-dev

Don't use Alpine Linux for Python images Unless you want massively slower build times, larger images, more work, and the potential for obscure bugs, you'll want to avoid Alpine Linux as a base image. For some recommendations on what you should use, see my article on choosing a good base image.
uWSGI doesn't work on bare Windows. (It might work on Cygwin, but that's probably not something you want to pursue.)
I found this on a GitHub thread. Modified it a bit and works perfectly fine for me on Python 3.5
apk add python3-dev build-base linux-headers pcre-dev
pip install uwsgi
Unfortunately the latest release of uwsgi does not support musl, a glibc alternative that alpine and a couple other distros use. Uwsgi will not build with musl when the ugreen plugin is included (see https://github.com/unbit/uwsgi/pull/522), so you still cannot pip install uwsgi. However, if you build uwsgi with the environment variable UWSGI_PROFILE=corethe build should succeed; but if will fail at runtime due to the issues solved here (https://github.com/unbit/uwsgi/pull/1210). This probably grim news -- I know it was for me -- but at least it looks like the uwsgi team is taking time to address its issues running on musl. Hopefully it will work in the next release.
