This Go application cleans up incomplete or abandoned Multipart uploads from the S3 storage backend (started by CreateMultipartUpload S3 API call) that have been created more than 12h ago and still not completed or aborted. Some S3 storage provider implementations behaves wrongly if too many Multipart uploads are created and not completed or aborted, causing docker registry to fail when pushing layers. Some related docker registry issues exist, like:

Once run, it will remove abandoned uploads created more than 12h ago (see cleanupHours constant in the code).
Please note that this checks the startedat file inside the upload path to detect when the upload was started, but this is specific to Docker registry.
If the S3 API is giving inconsistent responses (empty upload list, different list on every query), the script might need to be executed multiple times until the number of existing uploads is reduced.
It is recommended to run this as a scheduled job to perform a daily cleanup of incomplete uploads.
