Add-FnImportValue

Add-FnImportValue

SYNOPSIS

Adds the intrinsic function “Fn::ImportValue” to a resource property

SYNTAX

Add-FnImportValue [-ValueToImport] <Object> [<CommonParameters>]

DESCRIPTION

The intrinsic function Fn::ImportValue returns the value of an output exported by another stack. You typically use this function to create cross-stack references.

Note: The following restrictions apply to cross-stack references: * For each AWS account, Export names must be unique within a region. * You can’t create cross-stack references across regions. You can use the intrinsic function Fn::ImportValue to import only values that have been exported within the same region. * For outputs, the value of the Name property of an Export can’t use Ref or GetAtt functions that depend on a resource. * Similarly, the ImportValue function can’t include Ref or GetAtt functions that depend on a resource. * You can’t delete a stack if another stack references one of its outputs. * You can’t modify or remove an output value that is referenced by another stack.
