S3 buckets

Overview

This page describes the creation and management of S3 buckets in our OpenStack-based stoney cloud.

This section will guide you through the creation process in our OpenStack-based cloud.

Credential pair - Create

Create new EC2 credentials in OpenStack using the OpenStack-CLI:
