Actually, this logic with 3 for loops dont work because even if there is only 1 instance, it will loop many times depending with the same instance on the number of attributes inside. The output appears correct when only using the top 2 loops but it doesnt work when you apply it. It only creates the 1st of each instance.merge Function. merge takes an arbitrary number of maps or objects, and returns a single map or object that contains a merged set of elements from all arguments.

Using the merge () function. To merge two maps in Terraform, we primarily use the merge function. The merge function takes two or more maps as inputs and produces a single map that contains a union of the keys and values from all the input maps. When keys overlap, the value from the map that is later in the argument list will take precedence.
