@eliyas What route did you follow to achieve RDS setup?
Am trying to achieve the same and failing terribly at it.
Attempted to add the RDS hostname as a host in the inventory file but received a SSH connection issue to it that I have no idea off.
Attempted the other route of setting it manually on the properties file and my instance crashed with connection refused, the logs do not seem to point me to the root cause of this issue.
Please revert if you figured away around it. Thanks
