lgtm, @tiangolo what would you see this PR needing in order to be merged in? anything I can help with?

[tiangolo]

Thanks for the work @ProgEsteves and thanks for the offering @jaustinpage .

I just updated the base (Debian) image on the last weekend, to have the latest version of Python and Nginx. I also added the ability to run a prescript (e.g. for migrations) in the Flask image based on this one. I wanted to define how to do that before adding the Alpine version, to simplify things.

I wanted to do something similar for the Alpine version. I wanted to check what is the building process of the official Nginx image in the Alpine flavor and the best way to merge it with the Python image in the Alpine flavor.

My intention is to have the images very close to those two official base images. That will simplify things and facilitate features.

I hope to check and merge this (maybe with some adjustments) on the next weekend.

The Alpine flavor is definitely gonna happen soon. At least for Python 3.6.

[tiangolo]

First, many thanks for the hard work @ProgEsteves .

I wanted to follow the same procedure I used for the other "flavors" of this image. I started from a Python official base image and then I copied (most of) the contents of the Dockerfile for the official Nginx image.

That allows it to have the same behavior that users might expect as with the official image as some other advantages.

There are also a couple of minor improvements.

The current code is in: https://github.com/tiangolo/uwsgi-nginx-docker/tree/master/python3.6-alpine3.7

The Docker Hub image tag lives in: tiangolo/uwsgi-nginx:python3.6-alpine3.7 if you have the chance to test it.

It would be great if any of you has the chance to test it and let me know how it works.

[tiangolo]

Thanks for your work! It helped / inspired the creation of the new Alpine images. They have been there for a while and seem to be working, so I'll close this now. If you find any issue with them, please let me know.
