Dockerfile no longer works with debian:jessie as the base

[muxketeer]

When trying to build with this distro, it appears the apt-get update mirrors have been blocked or something.
ie.

Err http://security.debian.org jessie/updates/main amd64 Packages

E: Some index files failed to download. They have been ignored, or old ones used instead.
The command '/bin/sh -c apt-get update -y &&     apt-get install -y --no-install-recommends ca-certificates libimage-exiftool-perl python2.7 python-pip python-pyexiv2 wget make &&     pip install --upgrade pip setuptools &&     apt-get autoremove -y &&     rm -rf /var/lib/apt/lists/*' returned a non-zero code: 100

Perhaps change the first line of the Dockerfile to use debian:stretch ?
