Everybody is good!
As you all know, to use the client's network card name in cloud-init, you must fill in the exact name of the network card interface.
This was easy in version 7 and before, which usually started with EN0.
After version 8, however, the naming conventions for network cards changed a lot. In my own test environment, for example, I started with ENS3.
I'm not sure what naming convention it uses, which would make it impossible to specify nic information using cloud-init.
Could you help me explain how to deal with this problem?

Hi, this is called Predictable Network Names and it is the default policy for net interface naming in el8. There are a couple tricks you can do to mitigate that, you can disable it, or predict the name based on your configuration PCI slot etc [0]. There is a documentation for RHEL that explains it [1]. There is also another option and that's using a custom udev rule to assign whatever name you want based on some identifiers like MAC, PCI addr etc. Hopefully this helps.
