AWS cloudformation : how to set cluster name when creating a AWS::ElastiCache::ReplicationGroup resource

Question

I have a resource in the template of type AWS::ElastiCache::ReplicationGroup. When the stack is created, it is assigning a generated name when creating this cluster. Redis engine is being used. In case of AWS::ElastiCache::CacheCluster, there is a property called ClusterName which serves the same purpose. Is there a corresponding property here ?

Answer 1

For me, setting the ReplicationGroupId property worked. I used an input parameter called "ClusterName".
