Can I use s3cmd for object storage?

There is a powerful open source tool for managing object storage called s3cmd. It is available from and was originally written for managing object storage data in Amazon S3. It is also compatible with Catalyst Cloud object storage using the OpenStack S3 API.

While it is compatible, there is a gotcha with the Catalyst Cloud. In order to use s3cmd with the Catalyst Cloud, you need to customise the s3cmd configuration file.

Configuration changes

The following changes need to be specified in the .s3cfg file.

host_base =
host_bucket =
signature_v2 = True
use_https = True

Compatibility with S3

Please reference the Object Storage section for OpenStack Swift compatibility to S3 API’s.
