Application Scenario

After you upload a file to a bucket, you can access this file using the bucket's access domain name by default. If you want to use a custom domain name to access the file, bind the custom domain name to the bucket.

Assume that you have a domain name www.example.com and you upload an image image.png to an OBS bucket. As long as you bind www.example.com to the bucket, you can use http://www.example.com/image.png to access image.png. The steps below describe the configurations:

Create a bucket on OBS and upload file image.png to the bucket.
On OBS Console, bind www.example.com to the created bucket.
On the DNS server, add a CNAME record and map www.example.com to the domain name of the bucket.
Send a request for image image.png. After the request for http://www.example.com/image.png reaches OBS, OBS finds the mapping between the www.example.com and the bucket's domain name, and redirects the request to the image.png file stored in the bucket. This way, a request for http://www.example.com/image.png actually accesses http://Bucket domain name/image.png.

Constraints

Only buckets whose version is 3.0 or later support the configuration of user-defined domain names. The version number of a bucket is displayed in the Basic Information area.
By default, a bucket can have up to 20 user-defined domain names bound.
User-defined domain names currently allow requests over HTTP, instead of HTTPS.
A user-defined domain name can be bound to only one bucket.
The suffix of a user-defined domain name can contain 2 to 6 uppercase or lowercase letters.
