Terraform Resource Replication

Within #Terraform Providers, we can define a resource in such a way we could replicate multiple instances of them under different name. A recommended way to do this is by using a Terraform Meta Arguments# for_each. for_each will store a list of values, of type# set or map, into a variable called each.value. The following shows the configuration# example:

# In resource file
resource ... {
  filename = each.value
  for_each = toset(var.users)
}

# In variables.tf
variable users {
  type = list(string)
  defaults = [
    ...
  ]
}

Note: We can convert list to set with the built-in function toset().
