Usage: terraform state list [options] [pattern...]
|
||
|
|
|
||
|
|
List resources in the Terraform state.
|
||
|
|
|
||
|
|
This command lists resources in the Terraform state. The pattern argument
|
||
|
|
can be used to filter the resources by resource or module. If no pattern
|
||
|
|
is given, all resources are listed.
|
||
|
|
|
||
|
|
The pattern argument is meant to provide very simple filtering. For
|
||
|
|
advanced filtering, please use tools such as "grep". The output of this
|
||
|
|
command is designed to be friendly for this usage.
|
||
|
|
|
||
|
|
The pattern argument accepts any resource targeting syntax. Please
|
||
|
|
refer to the documentation on resource targeting syntax for more
|
||
|
|
information.
|
||
|
|
|
||
