Configuring a Custom Domain Name for a Bucket

Functions

OBS uses the PUT method to configure a custom domain name for a bucket. After the configuration is successful, you can access the bucket through the domain name.

To perform this operation, the user must be the bucket owner or the bucket owner's IAM user that has permissions required for configuring custom domain names.

Ensure that the custom domain name can correctly resolve to the OBS service through DNS.
