The ca-certificates package is installed in the slim images but not in the alpine images. Without it, HTTPS doesn't work (and so pip fails with standard settings).
It's not really hard to do a apk add ca-certificates but it's a bit unintuitive that there is this difference between the slim and alpine images.
