restore default repo list after disabling all

Following commands in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_atomic_host/7/html-single/managing_containers/index#set_up_for_rootless_containers
I unset all my repos

I now would like to revert to the former situation (which I stupidly did not backup)

Is there a list of default repos for RHEL7 that I coudl apply?

Thanks

I now manually reactivated:
* rhel-7-server-rpms/7Server/x86_64
* rhel-7-server-source-rpms/7Server/x86_64
do I need other basic ones?
