<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">I'm kind of uncomfortable as an op with the prebundled stuff. how do you upgrade things when needed if there is no way to pull updated images from a central place?<br>

Thanks,<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">hi hello again<br>
<br>
I believe you are talking about this bp <a href="https://blueprints.launchpad.net/magnum/+spec/cache-docker-images" target="_blank">
https://blueprints.launchpad.net/magnum/+spec/cache-docker-images</a><br>
then ignore my previous reply, that may another topic to solve network limited problem.<br>
<br>
I think you are on the right way to build docker images but this image could only bootstrap by cloud-init, without cloud-init<br>
the container image tar file are not loaded at all, but seems this may not be the best way.<br>
<br>
I'v suggest that may be the best way is we pull docker images while building atomic-image. Per my understanding, the<br>
image build process is we mount the image to read/write mode to some tmp directory and chroot to to that dircetory,<br>
we can do some custome operation there.<br>
<br>
I can do a try on the build progress(guess rpm-ostree should support some hook scripts)<br>
<br>

<div>
<p class="MsoNormal">We want to eliminate pulling docker images over the Internet on bay provisioning. There are two problems of this approach:</p>
</div>
<div>
<p class="MsoNormal">1. Pulling docker images over the Internet is slow and fragile.</p>
</div>
<div>
<p class="MsoNormal">2. Some clouds don't have external Internet access.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">It is suggested to build all the required images into the cloud images to resolved the issue.</p>

</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Here is a solution:</p>
</div>
<div>
<p class="MsoNormal">We export the docker images as tar files, and put the tar files into a dir in the image when we build the image. And we add scripts to load the tar files in cloud-init, so that we don't need to download the docker images.</p>
