rclone requires a config file. You can choose to either:
  1. Inherit the configuration from your AWS profile.
  2. Use only the rclone.conf file.
Option 1 is recommended in most cases, as it simplifies the use of other tools such as the AWS CLI and boto3.

​
Option 1: Use rclone with an AWS profile

rclone can inherit configuration from an AWS profile, usually found in ~/.aws/config. This means rclone and all other tools can share the same connection settings. 
[default]
type = s3
provider = AWS
env_auth = true
profile = default
no_check_bucket = true
In this example, the AWS profile is also named default. See Configure AWS CLI and boto3 for detail on configuration, including how to use federated credentials.
Static Access Keys are not recommended for production use. Use Workload Identity Federation instead. See Configure AWS CLI and boto3 for how to set up federated credentials that rclone can inherit through an AWS profile.
Example ~/.aws/config with static credentials: 
[default]
region = US-EAST-04A
endpoint_url = http://cwlota.com
aws_access_key_id = [ACCESS-KEY-ID]
aws_secret_access_key = [SECRET-ACCESS-KEY]
s3 =
    addressing_style = virtual
If you have permission to list buckets, test the configuration: 
rclone lsd default: -v

​
Option 2: Use rclone with a standalone config

Create an rclone remote in ~/.config/rclone/rclone.conf. Replace [ACCESS-KEY-ID] and [SECRET-ACCESS-KEY] with your actual values. Alternatively, sensitive credentials can be passed through environment variables.
Static Access Keys are not recommended for production use. Use Workload Identity Federation instead. This is the primary advantage of option 1.
[default]
type = s3
provider = Other
access_key_id = [ACCESS-KEY-ID]
secret_access_key = [SECRET-ACCESS-KEY]
endpoint = http://cwlota.com
force_path_style = false
no_check_bucket = true
For best performance, always use the LOTA endpoint (http://cwlota.com) when running inside a CoreWeave cluster. The primary endpoint (https://cwobject.com) is available when running outside of a CoreWeave cluster. These settings are critical when configuring rclone for AI Object Storage:
  • type: Must be s3.
  • provider: Must be Other.
  • force_path_style: Must be false. This forces rclone to use virtual-hosted style URLs. Path-style addressing is not supported.
  • no_check_bucket: Must be true. This prevents rclone from attempting to create or verify the bucket’s existence during operations.
Test the configuration: 
rclone lsd default: -v
