Answer 1

If you installed docker-engine from official repositories on your linux, it should be installed in /var/lib/docker, for your own configuration, find the respective path.

There is /var/lib/docker/image/aufs/repositories.json file where docker stores images with their sha256 values.

cat /var/lib/docker/image/aufs/repositories.json

Find the image you are looking after and copy it's sha256 hash somewhere.

Then:

ls /var/lib/docker/image/aufs/imagedb/content/sha256 -lash 

Find the sha265 value you found in repositories.json then look at the date.
