We are trying to deploy FreeIPA in our environment, this will be a mix of local servers and server to manage auth in EC2. We have a vpn tunnel setup and are able to communicate across it. Ina Amazon Linux 2 instance I was able to get FreeIPA installed as a client and am now trying to promote it to a replica. However I am getting the following error:
[ec2-user@freeipa-host ~]$ sudo ipa-replica-install --setup-ca --ssh-trust-dns --mkhomedir --setup-kra

admin@domain.NET:
ipa : ERROR Reverse DNS resolution of address 10.10.52.158 (
infra-freeipa1-aws.gatewayblend.net) failed. Clients may not function properly. Please check your DNS setup. (Note that this check queries IPA DNS directly and ignores /etc/hosts.)
Doing some digging on Google I found this
https://yyhh.org/blog/2017/12/freeipa-aws-ec2.
In this instance DNS was NOT setup on the FreeIPA machine in AWS and fqdn were setup in /etc/hosts and /etc/hostname.
1) is the the preferred method?
2) Could I still install DNS on the server in AWS to ONLY manage an internal zone?
