Hi,

I’m creating an EC2 instance, then assigning an eIP to it, after I want to create a route53 entry using the eIP’s CNAME (eip task only returns ip\_address not the dns name sadly).

My current approach is to attempt to refresh the EC2 instance information (from the control host, I can’t login on the box yet; so no ec2\_facts), and from the refreshed information pull the public\_dns\_name.  
However I can’t find a simple way to refresh the instance information (other than aws ec2 describe-instances --filter … and then doing all kinds of magic to have ansible understand it’s output)…

Anyone who’s doing something similar or who could give me some pointers?

Thanks,  
Nico.
