Is it possible to launch instance based on parameter passed to the heat template
For example, I have two nova instances defined in the template. 1. Oracle 2. MSSql and I have a boolean parameter isOracle that will be specified by the user when the stack is created. Similar to imageId and flavorId
Is there a tag/condition I can use so that only one of the instances are launched. So lets say, if isOracle is true, only instance 1 will be launched, and vise versa. So even if there are 2 nova instances defined in the template, only one will be brought up depending on the parameter input.
