Each image is a scratch image containing a single disk at /disk/image.qcow2. It is not runnable; use it as a disk source (e.g. KubeVirt containerDisk) or extract the qcow2:
id=$(docker create floatingcontainers/<image>:<tag> /bin/true)
docker cp "$id":/disk/image.qcow2 ./image.qcow2
docker rm "$id"Images are built manually via the Build CAPI OCI Image workflow (Actions → Run workflow).
