/// CONNECT A PROVIDER / UCLOUD US3

UCloud US3

UCloud US3 is S3-compatible and authenticates with a Public Key (公钥, the Access Key ID) and Private Key (私钥, the Secret).

What you need

• A Public Key (公钥, Access Key ID) and Private Key (私钥, Secret).
• The bucket name and region.

Create API keys

1. Sign in to the UCloud console and open API Keys.
2. Create an API key (SMS-verified).
3. Copy the Public Key (公钥, Access Key ID) and Private Key (私钥, Secret).

Endpoint & region

https://s3-<REGION>.ufileos.com — substitute your US3 region (20+ available). Note the s3- prefix: this is the S3-compatible host, not the native <region>.ufileos.com. Use path-style addressing.

Connect the Fleet

1. From the Fleet page, click Create Fleet and pick Access Keys.
2. Paste the Public Key (Access Key ID) and Private Key (Secret).
3. Set the endpoint for your region.
4. Click connect.

Supported features

US3 supports lifecycle and storage classes — auto-cooling tiers (Standard → Infrequent Access → Archive). S3 versioning is always disabled, and CORS, bucket policies, object tags, and Object Lock are not in its S3 surface.
