Stream Output #3

Closed kellerkind closed 10 years ago

kellerkind commented 10 years ago

Can you make yumbootstrap output optional compatible with tars input stream format? This would be great to create yum based docker images in a single step. 

$ yumbootstrap --verbose --tar-stream centos-6 - | docker import - <image_name>

I like the idea, but given the circumstances, I don't quite see much gain.

Yum needs to run post-install scripts. It can't just directly produce tar archive and a temporary directory would be necessary. It would save a command like this:

(TMP=`mktemp -d`; yumbootstrap --verbose centos-6 $TMP && tar cf - -C $TMP .; rm -rf $TMP) | docker import - <image_name>
