[Andrey Ptashnik]

Hi Martin,

Thank you for a catch! I just noticed that I was missing the dot you mentioned!

Regards,

Andrey

Hello Team,

We are hosting a few servers at Amazon and using their Elastic Load Balancing service that gives us a link to a load balancer in the following format:

webserver-1234567890.us-east-1.elb.amazonaws.com

I was looking for a ways to implement a shorter alias using CNAME like:

webserver.mydomain.com   pointing to longer link from the load balancer   webserver-1234567890.us-west-2.elb.amazonaws.com

Is there a way to do it in RHEL 7.1 with IPA server 4.1.0 using different domain names?

Regards,

Andrey



Hello Andrey,

If I understand correctly, IPA manages mydomain.com zone, so adding CNAME record should be simple:

ipa dnsrecord-add mydomain.com webserver --cname-rec='webserver-1234567890.us-west-2.elb.amazonaws.com.'   # <-- do not forget to add dot at the end

If mydomain.com is managed outside IPA, the CNAME should be set on that external server, IPA cannot help in this case.
