Manage user domains

Last update: July 18 2025

You can distribute objects in a public bucket under the guise of your (user) domain. The user domain is added at the bucket level. You can get an object through a custom domain by following the link.

You can add custom third-level domains and above.

You can add external DNS hosted domains or domains delegated to Selectel DNS hosting.

You must add TLS (SSL) certificates for all user domains.

Add a custom domain from Selectel DNS hosting

You can add a domain to an existing DNS hosting domain zone that is delegated to Selectel DNS hosting, or create a new zone during the domain addition process.

After adding a domain, a resource record for S3 communication (CNAME record) will be automatically created pointing to the public domain of the bucket.A domain can only have one CNAME record.If you already have a CNAME record, it will be applied, no duplicate record will be created.

If the automatically created CNAME record conflicts with other records, you will need to resolve the conflict yourself on your DNS hosting side.

2. Add a domain to the bucket.
3. Add a TLS (SSL) certificate.
