Pavel, I know my team uses packer.io to build our golden images for our infrastructure. I know we build qcow2 and AMI images and have them uploaded to our AWS, OpenStack, and RHV instances. I would be willing to sit down and help test this with you if you would like.

Hello infra!
Currently, in Copr team we are periodically preparing those kinds of images for
our VM builders:
- x86_64 AMI image for AWS
- aarch64 AMI
- x86_64 image for hypervisors
- ppc64le qcow2 image (uploaded to Power9 OpenStack and to our Power8 hypervisors)
- s390x qcow2 (built in IBM Cloud)
- internally we build also x86_64 images for OpenStack
The way we do this now is pretty complicated:
- we start with the officially provided Fedora images (AMI/QCOW2)
- we modify and update them using ansible scripts and/or libguestfs
- then the images are uploaded, and tested in our development stack
- and if everything is OK, then these images are used in production
Some more info https://docs.pagure.org/copr.copr/how_to_upgrade_builders.html
This is a tedious and repetitive list of tasks, and I'm sure we
should/could automatize some parts. At least it would be awesome if we
could try to trigger the build(s) for all the images by "a single button",
somehow, somewhere... So I am here to ask you how you would do this.
- I thought the answer is Image Builder, but there's a missing support for
Fedora ppc64le and s390x targets for now (rhbz#2040685).
- livemedia-creator, seems to be a bit related to Image Builder but I was told
some time ago that AMI support is experimental, the docs say
"At this time I have not tested the image with EC2. Feedback would be
welcome."
- There's a Packer software (packer.io) used by testing farm folks (the tooling
is not available in Fedora yet).
- Koji is able to build some images using Kickstarts. This one looks like
low-hanging fruit. Existing and working solution, we could built on top of
of the maintained fedora-kickstarts files that we "use" anyway (through the
pre-built official images). But I'm not sure if our team could be allowed to
use Koji like this, and provide additional *ks files?
Are there any other possibilities? Opinions?
Thanks, Pavel
