Overview

This node allows you to remove (delete) an object from a specified bucket in a MinIO storage server. It is useful for automating the cleanup or management of files stored in MinIO, such as deleting outdated backups, removing temporary files after processing, or managing user-uploaded content.

Example scenarios:

  • Automatically delete processed files from a MinIO bucket after workflow completion.
  • Remove obsolete or expired data objects as part of a scheduled maintenance workflow.
  • Clean up user-specific files when a user account is deleted.

Properties

Display Name Type Description
Bucket Resource Locator The target bucket from which the object will be removed. You can select from a list or enter the name manually.
Key String The key (name/path) of the object to remove from the bucket.
