Object storage (S3)

Your OpenStack project also gives you access to the S3-compatible object store. This is the same Ceph object storage documented under Ceph → Object storage (S3); the full endpoint, tool configuration, and pricing live there.

The short version:

  • Endpoint: https://s3.orion.sunetvdc.se

  • Credentials: S3 access keys are issued as EC2 credentials from your project. Authenticate the OpenStack client with an unrestricted application credential for that project, as described in S3 authentication, then create a pair:

    openstack ec2 credentials create

    This prints an access and secret pair scoped to your project and user, separate from the application credential's ID and secret. Horizon no longer displays S3 keys in View Credentials; use the CLI to view and revoke them.

Use object storage for data you want to reach over the network from anywhere (backups, datasets, artifacts) rather than as a disk attached to an instance. For disks, use block storage.
