I can see that vda is partioned into four partitions, but it can’t be a complete installation and I cannot boot from disk.
The OKD docs say that you’ve to reboot during installation and then the ignition-config is applied. After the installation you should get this messages:
“Ignition: ran on 2022/03/14 14:48:33 UTC (this boot)
Ignition: user-provided config was applied”
I don’t know how to get a proper installation, because there is no error message, just that it has been installed.
When you run coreos-installer all it is doing is writing out an image file to disk and also copying in your Ignition config that will then run on the next boot. If you have fast disks then it writing out in <20s is reasonable.
What you need to do now is reboot and on that first boot Ignition will run and do the things it’s been told to do. When Ignition runs that is when the machine gets configured.
