# Since Docker users are looking for the smallest possible final images, the # following emerges as a very common pattern: # RUN apt-get update \ # && apt-get install -y <packages> \ # && <do some compilation work> \ # && apt-get purge -y --auto-remove <packages> # By default, APT will actually _keep_ packages installed via Recommends or # Depends if another package Suggests them, even and including if the package # that originally caused them to be installed is removed. Setting this to # "false" ensures that APT is appropriately aggressive about removing the # packages it added. # https://aptitude.alioth.debian.org/doc/en/ch02s05s05.html#configApt-AutoRemove-SuggestsImportant Apt::AutoRemove::SuggestsImportant "false";
