The workspace name can be overridden by setting a TF_WORKSPACE environment variable. If this is done, we should still validate the resulting workspace name; otherwise, we could end up with an invalid and unselectable workspace. This change updates the Meta.Workspace function to return an error, and handles that error wherever necessary.

Usage: terraform state list [options] [address...]
|
|
|
|
List resources in the Terraform state.
|
|
|
|
This command lists resource instances in the Terraform state. The address
|
|
argument can be used to filter the instances by resource or module. If
|
|
no pattern is given, all resource instances are listed.
|
|
|
|
The addresses must either be module addresses or absolute resource
|
|
addresses, such as:
|
|
aws_instance.example
|
|
module.example
|
|
module.example.module.child
|
|
module.example.aws_instance.example
|
|
|
|
An error will be returned if any of the resources or modules given as
|
|
filter addresses do not exist in the state.
|
|
|
|
Options:
|
|
|
|
-state=statefile Path to a Terraform state file to use to look
|
|
up Terraform-managed resources. By default, Terraform
|
|
will consult the state of the currently-selected
|
|
workspace.
|
|
|
|
-id=ID Filters the results to include only instances whose
|
|
resource types have an attribute named "id" whose value
|
|
equals the given id string.
