In Dockerfile-slim, you remove wget, here you remove.. everything? Or what does apt-get purge without an argument do?

I was mistaken about what this change did, and am going to drop it in favor of getting the other changes in.
I had hoped that apt-get purge -y --auto-remove wget would remove wget, anything unnecessary, as well as package metadata, but it appears it doesn't.

While looking at some of
docker-library'sDockerfiles, I realized that our currentDockerfileformat could be improved, and we should try to roughly match theirs. This PR is a collection of changes that hopefully make things better.References:
