Create a new bucket https://cloud.linode.com/object-storage/buckets/create, in the Label write the name of the subdomain of your site s3.example.com
Next, in the DNS settings of the domain, you need to configure the CNAME record so that the subdomain is directed to the created bucket. In our case, the main domain is on CloudFlare. Cloudflare provides a free SSL certificate, so there is no need to issue a separate certificate for the subdomain.
Migrate existing files and folders from the old bucket to the new s3.example.com using CyberDuck, for example. Files and folders are transferred by dragging and dropping from the old bucket to the new one.
