Indeed, I don't think you can use ISO as it is, you'll need to figure out
what is inside. If it's an RPM (as I assume), you'll need to extract it and
install into the ramdisk.

If nothing helps, you can try building a ramdisk with CentOS 7, the (very)
recent versions of ironic-python-agent-builder allow using Python 3 on
CentOS 7.
