Feature Request: Add build-iso workflow ...

Great job on the presentations guys! I heard that you guys were still not using bootc-image-builder to generate ISOs and then the followup from the guys asking if he could make AMIs made me start thinking. I found the ticket here to use bootc-image-builder but theres not much talk of requirements.

The biggest issue ive dealt with when using this personally in CI is the storage limits

tulip•3/9/25, 2:39 AM

ZZoid ah well then thats super easy. Ill start there

we are just storing the images on aws buckets

ZoidOP•3/9/25, 2:41 AM

that makes WAY more sense. I was gonna ask how youre getting around that 2GiB limit

tulip•3/9/25, 2:41 AM

but i believe that if your image is small/compressed enough you can store it on gh actions artifacts or releases

tulip•3/9/25, 2:41 AM

bib makes really nice ISOs

tulip•3/9/25, 2:41 AM

we had ISOs that were like 3GB

tulip•3/9/25, 2:41 AM

at the start

tulip•3/9/25, 2:41 AM

i think they are still that small

ZoidOP•3/9/25, 2:41 AM

it sure does. been using that for a while. Mine are about 3GB as well

ZoidOP•3/9/25, 2:44 AM

hmm. I can work with this. So were gonna need to provide an optional template where a user can add their own S3 details in to upload their builds. I dont think it makes sense right now to try and compress it so highly that it may/may not hit that 2GiB limit as part of the actions artifacts. Maybe as part of the action artifact it spits out a s3 url of the finished product(s)?

Interesting that for the bluefin pipeline the bootc-image-builderbootc-image-builder that yall are using is ghcr.io/centos-workstation/bootc-image-builder:latestghcr.io/centos-workstation/bootc-image-builder:latest as opposed to the image in the docs which says quay.io/centos-bootc/bootc-image-builder:latestquay.io/centos-bootc/bootc-image-builder:latest

Anyone know if there is a difference? I guess Carl put that there or something to help with speed?

nope nothing

tulip•3/9/25, 3:41 AM

its just an older fork

tulip•3/9/25, 3:41 AM

because we had some failures with the recent bootc-image-builderbootc-image-builder images

ZoidOP•3/9/25, 3:44 AM

yeah i ran into those myself. especially around rootfsrootfs. thanks for the context

James•3/9/25, 3:52 AM

The failures were due to bibbib images being way out of date. So we forked and built it ourselves

ZoidOP•3/9/25, 3:55 AM

oh wow, thats important context. Any ideas why the images on quay arent being updated?

ZoidOP•3/9/25, 3:56 AM

looking at the registry it did go about 3 weeks without updates and got a new image 2 days ago

James•3/9/25, 4:50 AM

They were having some issues with their build pipeline. But simple enough to build it yourself
