Build an image locally? (T2-Atomic specifically)

Hi everyone!

I asked a few days ago in this issue, but was curious if anyone here would know how to build an ISO of the T2-Atomic-Bluefin image. I’m trying to build an ISO of the newest container image kindly provided by the t2-atomic project, so I can install bluefin on my wife’s old macbook without having to find a usb-mouse, usb-keyboard and usb-to-ethernet dongle to install silverblue, then rebase to the t2-atomic image.

  • this build guide in the docs is very bluefin specific.
  • I also saw that the t2 atomic build was originally forked from Blue Build, and I saw in their docs that it’s possible to build an ISO image from a container image.

Does anyone have experience with this? I’m trying
sudo docker run --rm --privileged --volume ./iso-output:/build-container-installer/build --pull=always ghcr.io/lauretano/t2-atomic-bluefin:latest

But then get

latest: Pulling from lauretano/t2-atomic-bluefin
Digest: sha256:7ce234cee1454ac73de33891ea110c5006129d9f03855699631aede97b761728
Status: Image is up to date for ghcr.io/lauretano/t2-atomic-bluefin:latest

Thank you for any pointers!
