To integrate aws-nuke in reaper, it is divided into multiple components by separating the scan and delete operations. In order to achieve this, some of the aws-nuke code is copied, modified and extended. The resource data scanned by aws-nuke is converted to the reaper's native resource type to be listed in a coherent manner with the other reaper providers and also support json output. Applying the retention period/age filter to aws-nuke resources also requires post processing of the resources after scanning and before deleting. aws-nuke doesn't provide option for custom filters. The scanned resources are passed through a custom filter, implemented as an extension of the Nuke type, which understands the custom createdat timestamp format and filters the resources accordingly.
