alpine image slimmed down to 25 MB

[tobwen]

With the help of this, I was able to fix the lib c bug of Python's util, which will get fixed in v3.8 and causes trouble with Shapely. Sure, there might be a better patch than the Alpine one, but this one is working fine in this case.

My edit of this dockerfile isn't elegant, but it drops all the building dependencies (f.e. the huge libc & gcc stuff) and results in a small image of less than 30 MB:

Maybe would could just set the automatically installed packages on "hold", like the DPKG-way, to protect them from automatic removal?

Sorry, I didn't see your issues, here. I will take a look at it on next weekend...

In the meantime things progressed: Alpine is not the best choice these days. Now using "slim" Debian packages. Compressed size around 190MB.
