The web client – OpenStack Horizon Dashboard

This chapter provides instructions for using Allas with the user-friendly OpenStack Horizon Dashboard.

OpenStack documentation for managing buckets over the web interface:

The OpenStack dashboard has a small subset of object storage functionalities. The available operations:

Create a new bucket
Upload an object (max. 5GB)
View objects and buckets
Download an object
Remove objects and buckets
Make buckets public or private

Create a bucket

1. Go to and login

2. In the menu on the left, navigate to Project | Object Store | Containers
(A container corresponds to a bucket)

"Creating a container"
Figure Creating a container

3. Press the +Container button and name the bucket (see the checklist for naming a bucket). If you choose to make the bucket Public, the contents of the bucket can be viewed via the internet.

Upload an object

The data upload function of this interface works only for files smaller than 5 GB.

1. Choose the desired bucket and press the upload symbol on the right.

"Upload object"
Figure Uploading an object

2. Choose the object on your computer and name it. Note: Do not use non-ASCII characters (ä, ö etc.).

3. Upload the object. It will appear in your container. You can also create pseudo folders for the objects with the +Folder button next to the upload symbol, e.g. to organize the objects into folders.

View objects via the internet

If the bucket containing the objects is set to public, the objects can be viewed via the internet by anyone who knows the URL. This setting can be changed in by choosing the container and selecting the Public Access setting:

"Making object public or private" Figure Making an object public or private

For example, the public object called my_fish in the container my_fishbucket can be viewed with the URL Note that in cases, where a large object is stored to Allas as segments, you must set to public also the segments containing bucket ( e.g. my_fichbucket_segments ).

Download an object

Download an object by clicking the Download button on the right side of the object's name.

Remove objects and buckets

Objects can be removed by expanding the dropdown menu on the right next to the Download button and choosing Delete.

Buckets can be removed only when they are empty. Hence, all objects in a bucket must be removed or moved elsewhere before the bucket can be deleted. Remove a bucket by clicking the trashcan symbol next to the bucket's name.

"Removing object or container" Figure Removing an object or a bucket

Alternatively, and especially if you want to remove several objects at once, you can choose the objects by selecting the small boxes on the left side of the object names and choosing the trashcan symbol on the red background in the upper right corner.
