Hello,
What about adding an EIP to the instance(s)?
Because that changes the game completely making the registered ec2
instances info outdated (at least the IP-related one).
How about cycling through Route53 with those EIPs? Has anyone done that
successfully? Don't want to hijack this thread, but I find this rather
relevant.
I know some would indicate the ec2_facts module, registering the output
from ec2_eip or using the add_host module but I couldn't do it in any way
so even a pseudo-code would be appreciated.
Thanks !
