» Resource Addressing
terraform state subcommands make heavy use of resource addressing
for targeting and filtering specific resources and modules within the state.
Resource addressing is a common feature of Terraform that is used in
multiple locations. For example, resource addressing syntax is also used for
-target flag for apply and plan commands.
Because resource addressing is unified across Terraform, it is documented in a single place rather than duplicating it in multiple locations. You can find the resource addressing documentation here.
