A bucket is a container for storing objects in a compartment within a namespace. A bucket is associated with a single compartment. The compartment has policies that indicate what actions a user can perform on a bucket and all the objects in the bucket. For more information, see Managing Buckets.
To use any of the API operations, you must be authorized in an IAM policy. If you are not authorized, talk to an administrator. If you are an administrator who needs to write policies to give users access, see Getting Started with Policies.
