Domain name management

Prerequisites

• Your application is published. For more information, see Publish.

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

Limitations

• If you embed your web application into a third-party website or application, such as a web-based backend or a mobile app, you must configure an HTTPS acceleration service.

• Each application can be bound to a maximum of five domain names, but a domain name can be bound to only one application. If the domain name that you want to bind is already bound to another application, the binding fails and the following message appears: domain already exit. In this case, you must unbind the domain name from the web application that currently uses it before you can bind it to the target application.

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 Recently Developed section, find your target application in the Web Application list and click its name.

3. In the web application editor, click the Application Settings icon in the far-left pane.

4. On the Application Settings page, click the Domain Names tab, and then click Add.

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

   Note

   You can bind a maximum of five domain names to each application.

Configure domain name resolution and HTTPS acceleration

This section explains how to use Alibaba Cloud DNS and Alibaba Cloud CDN to configure domain name resolution and HTTPS secure acceleration. For more information, see Add a DNS record and Configure an HTTPS certificate.

1. Log on to the CDN console. In the navigation pane on the left, click Domain Name Management.

You can find your application's default domain name on the Domain Name Management tab. This system-assigned domain name has the format xxxxxx.vapp.cloudhost.link.
         Priority	Origin priority allows for a primary/secondary configuration where requests are routed to the higher-priority (primary) origin first.
         Weight	You can use the default weight.
         Port	You can use the default port.

      3. Click OK to complete the configuration.
