Domain name management

Prerequisites

You have purchased a domain name. For more information, see Alibaba Cloud Domain Name Service.

Limitations

You can bind up to five domain names to an application, but a domain name can be bound to only one application. If you attempt to bind a domain name that is already associated with another application, the binding fails with the error message: domain already exit. In this case, you must unbind the domain name from the existing application before binding it to the new one.

Bind a domain name

1. Log on to the IoT Studio console. In the upper-left corner, select the target instance. In the navigation pane on the left, click App Development.

2. In the Recent Development section, find your target application in the Mobile Applications list, and click the application name.

3. In the mobile application editor, click the Application Settings icon on the far left.

4. On the Application Settings page, select the Domain Name Management tab and click Add.

5. In the Add Domain Name dialog box, enter your domain name and click OK.

   Note

   You must add a domain name to your mobile application before publishing it. You can bind a maximum of five domain names.
