Configuring Bucket Inventories

Functions

OBS uses the PUT method to configure bucket inventories. Each bucket can have a maximum of 10 inventories. For more information about the use and limitations of bucket inventories, see Bucket Inventory in the Object Storage Service User Guide.

To perform this operation, ensure that you have the PutBucketInventoryConfiguration permission. By default, the bucket owner has this permission and can grant it to others.

For more information about permission control, see the permission control in the OBS Permission Configuration Guide.
