May be a dumb question...

If we're excluding DNF, RPM, etc. for a slimmer base image during runtime,
how are we describing the best practices for build? Is the intention that
you should always be pulling in a separate tool container to assist with
the build process?

Hi Bill,

Ideally, we'd like to remove dnf and other tools that build the image 
because it's like shipping the "BuildRequires" fields as part of a 
binary rpm.


In place of dnf, rpm, etc., we'd like to have a "builder tool" that 
volume mounts dnf or other tools during the build, or builds and 
produces an image using outside tools. So yes, the intention would be to 
pull in a separate tool container to assist with the build process.


Hope that helps

Minimizing the fedora docker base image footprint

[Courtney Pacheco]

Hi everyone,

I've spent some time trying to minimize the footprint of the Fedora 
docker base image. Overall, I managed to reduce its size by 39.9%.


A summary of the work I did can be found here: 
https://gist.github.com/iamcourtney/1a4af7c4289014f57080

I essentially looked at which packages were being installed to the base 
image and tried to determine which of those packages could be turned 
into weak dependencies and which of those packages we could possibly 
break up.


If possible, I'd like some feedback on the work I did. Comments and 
criticism are more than welcomed! I realize there may be some 
controversy in terms of what I chose to remove and what I chose to turn 
into weak dependencies, but I would like to hear your thoughts either way.


As a side note, I originally posted my preliminary results to 
atomic-devel list a few weeks ago, but I used some of the feedback I got 
to make improvements. I also was able to reduce glibc with the help of 
Carlos O'Donell.


Thanks!
