Thank you for the quick and kind answer.
Currently there is no way to use Ansible in CoreOs… network setup (nmstate API), or simply uploading a file (ipxe.iso for rebooting the system from PXE).
Let me see if I understand you correctly.
You want to manage a CoreOS (VM? container?) system using Ansible?
What version of Ansible are you using? What is your control node platform?
It fails due to some python SELinux libraries missing, only shell/cmd modules work for doing simple tasks.
Then it sounds like this isn't just a system roles issue, but an Ansible issue, if you can't even use builtin modules. We can try to help you, but you might get more help on a general Ansible list/forum.
