This guide shows you how to configure the s3cmd command-line tool to connect to CoreWeave AI Object Storage so you can manage buckets and objects from your terminal.
s3cmd doesn’t natively support Workload Identity Federation. For production workloads, consider a tool that supports WIF, such as the AWS CLI or rclone.
s3cmd requires your Access Key, default Region, endpoint, and other information to use AI Object Storage. To start the interactive configuration: 
s3cmd --configure
When prompted, provide the following values:
FieldValue
Access KeyThe Access Key created by the AI Object Storage API.
Secret KeyThe Secret Key created by the AI Object Storage API.
Default RegionThe CoreWeave Availability Zone.
S3 Endpointcwobject.com is the primary endpoint. cwlota.com is the LOTA endpoint.
DNS-style template%(bucket)s.cwobject.com is the primary template. %(bucket)s.cwlota.com is the LOTA template.
Path to GPG programDefaults to /usr/bin/gpg.
Use HTTPS protocolBoolean value indicating whether to use the HTTPS protocol. Defaults to True.
HTTP Proxy server nameName of the HTTP Proxy server, if applicable.
HTTP Proxy server portPort number of the HTTP Proxy server, if applicable.
Leave the remaining fields blank or press Enter to accept the default values. Test and save the configuration when prompted. After the configuration is saved, s3cmd is ready to interact with AI Object Storage. By default, s3cmd stores its configuration in $HOME/.s3cfg.
