Mixed use of docker and $DOCKER

[remohammadi]

Example of docker usage in the script:

cat containers.keep |
xargs -n 1 docker inspect -f '{{.Config.Image}}' 2>/dev/null |
sort | uniq |
xargs -n 1 docker inspect -f '{{.Id}}' 2>/dev/null |
sort | uniq > images.used

Is this by design? Or can I make a pull request to unify the method of calling docker?

Hey @remohammadi . Pretty sure this is just an oversight - would be great if you could submit a PR, otherwise I'll try to pick it up in the coming days.
