As suggested on jessfraz/blog#15 (comment), I bring you this super PR. I think
apt-get
could be similarly improved, but I haven't found any official doc for doing something like apk does.This enables us to remove the following patterns that required a
rm -rf /var/cache/apk
:apk update
apk add --update
apk add --update-cache
Supported since alpine 3.3.
