Create an Object Storage Container

Overview

Containers (buckets) are the top-level namespaces within your object storage account. All objects must reside in a container. Container names must be unique within your account, and the storage policy assigned at creation time cannot be changed afterward.

Prerequisites

An active Polystack account with appropriate permissions
Access to the Polystack Dashboard or CLI configured with credentials
API credentials sourced (source openrc.sh)

Create a Container

Dashboard
CLI

Navigate to Object Storage

Navigate to Storage > Object Storage.Click Create Container to open the creation dialog.

Configure container settings

Field	Description
Container Name	Unique name within your account (e.g., `app-backups`)
Container Access	`Private` (default) or `Public` — public enables anonymous read
Storage Policy	Select the replication policy appropriate for the data tier

Setting container access to Public makes all objects in the container accessible to anyone with the storage endpoint URL — including external parties. Use public access only for intentionally public assets such as static web content.

Create the container

Click Confirm. The container appears in the list immediately.

Container appears in the Containers list and is ready for object uploads.

Container Naming Rules

Rule	Detail
Uniqueness	Must be unique within your account (project)
Length	1–256 characters
Characters	Any UTF-8 character except `/`
Case	Case-sensitive — `app-backups` and `App-Backups` are different containers

List and Manage Containers

openstack container list

openstack container show app-backups

openstack container delete app-backups

Containers with objects cannot be deleted until all objects are removed. Use openstack object list app-backups to view contents before deletion.
