Amazon S3 Empty and Delete a Bucket

  title: Amazon S3 Empty and Delete a Bucket
  summary: List the bucket, batch-delete its objects, then delete the empty bucket.
  description: >-
    A full teardown flow for Amazon S3. A bucket cannot be deleted while it still
    contains objects, so the workflow first lists the objects, then removes a
    supplied set of keys with a single DeleteObjects request, and finally deletes
    the now-empty bucket. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
