I have ELB,Instance,RDS under this aws cloudformation JSON template.. I want to use waitCondition to run after creation on myRds and then pass RDS endpoint.address to another template located in S3 bucket/or anywhere.. Can any1 please help me with this.. I am not getting enough documentation on amazon which shows how to pass rds enpoint.address or anything to another template right after creation of RDS.
