aws.lambda¶
Filters¶
cross-account¶
Filters lambda functions with cross-account permissions
The whitelist parameter can be used to prevent certain accounts from being included in the results (essentially stating that these accounts permissions are allowed to exist)
This can be useful when combining this filter with the delete action.
