    description: >-
      The Longhorn Manager exposes a REST API for volume lifecycle management
      including creating, attaching, detaching, and deleting volumes. It also
      provides endpoints for snapshot management, backup operations, node
      management, engine image management, and system settings configuration.
      The API is used by the Longhorn UI and can be accessed directly for
      automation.
