Our images are now available on the public Google Container registry. For python, you can grab the image at gcr.io/google_appengine/python-compat
It is important to note that you must do the following to use that image:
docker pull gcr.io/google_appengine/python-compat
You can change the FROM line in your Dockerfile. Also, it's important to note that this image does not have the GAE SDK included, but you can add most python libraries yourself.
