Terraform Count Meta-Argument – How to Use It & Examples

Resource blocks are the building blocks of the Terraform language, describing one or more infrastructure objects like virtual machines, gateways, load balancers, etc. The count meta-argument simplifies the creation of multiple resource instances without having to repeat the same resource block multiple times. It can be used with both resource and module blocks. The index attribute within the count object is a sequential number for each instance starting from 0, which can be used as part of the name to make them uniquely identifiable. The count argument supports using numeric expressions and can change the value conditionally.
