Resource Addressing

The 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 the -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.
