Steve,
<div class=""><br class="">
</div>
<div class="">I will defer to the experts in openstack-infra on this one. As long as the image works without modifications, then I think it would be fine to cache the upstream one. Practically speaking, I do anticipate a point at which we will want to adjust
something in the image, and it will be nice to have a well defined point of customization in place for that in advance.

Iım very interested in having an image locally cached in glance in each<br class="">
of the clouds used by OpenStack infra. The local caching of the glance<br class="">
images will produce much faster gate testing times. I donıt care about<br class="">
how the images are built, but we really do care about the performance<br class="">
outcome.<br class="">

<blockquote type="cite" class="">Hi<br class="">
I wanted to start a discussion on how Fedora Atomic images are being<br class="">
built. Currently the process for generating the atomic images used<br class="">
on<br class="">
Magnum is described here:<br class="">
<a href="http://docs.openstack.org/developer/magnum/dev/build-atomic-image.htm" class="">http://docs.openstack.org/developer/magnum/dev/build-atomic-image.htm</a><br class="">
l.<br class="">
The image needs to be built manually, uploaded to fedorapeople, and<br class="">
then<br class="">
consumed from there in the magnum tests.<br class="">
I have been working on a feature to allow diskimage-builder to<br class="">
generate<br class="">
these images. The code that makes it possible is here:<br class="">
https://review.openstack.org/287167<br class="">
This will allow that magnum images are generated on infra, using<br class="">
diskimage-builder element. This element also has the ability to<br class="">
consume<br class="">
any tree we need, so images can be customized on demand. I generated<br class="">
one<br class="">
image using this element, and uploaded to fedora people. The image<br class="">
has<br class="">
passed tests, and has been validated by several people.<br class="">
<br class="">
So i'm raising that topic to decide what should be the next steps.<br class="">
This<br class="">
change to generate fedora-atomic images has not already landed into<br class="">
diskimage-builder. But we have two options here:<br class="">
- add this element to generic diskimage-builder elements, as i'm<br class="">
doing now<br class="">
- generate this element internally on magnum. So we can have a<br class="">
directory<br class="">
in magnum project, called "elements", and have the fedora-atomic<br class="">
element<br class="">
here. This will give us more control on the element behaviour, and<br class="">
will<br class="">
allow to update the element without waiting for external reviews.<br class="">
<br class="">
Once the code for diskimage-builder has landed, another step can be<br class="">
to<br class="">
periodically generate images using a magnum job, and upload these<br class="">
images<br class="">
to OpenStack Infra mirrors. Currently the image is based on Fedora<br class="">
F23,<br class="">
docker-host tree. But different images can be generated if we need a<br class="">
better option.<br class="">
<br class="">
As soon as the images are available on internal infra mirrors, the<br class="">
tests<br class="">
can be changed, to consume these internals images. By this way the<br class="">
tests<br class="">
can be a bit faster (i know that the bottleneck is on the functional<br class="">
testing, but if we reduce the download time it can help), and tests<br class="">
can<br class="">
be more reilable, because we will be removing an external dependency.<br class="">
<br class="">
So i'd like to get more feedback on this topic, options and next<br class="">
steps<br class="">
to achieve the goals. Best<br class="">
<br class="">
