Try WordPress on Azure App Service!

Deploy to Azure


Once you set up a new WordPress website on App Service, you can access your website using the URL <app-name> Custom Domains are domain names that reflect your brand or company. For example, is the custom domain used by Microsoft for their website. In this article, we will learn about how we can use Custom Domains and subdomains with our WordPress website on App Service.


You can buy an App Service domain and use it with your WordPress website. App Service Domains are custom domains that are managed directly in Azure. Also, if you have an existing custom domain registered with any other registrar, you can use that with your WordPress website as well. We will also learn how we can add subdomains if we have a custom domain.


I. Buying an App Service Domain


Step 1: Go to the App Service page. You can see that the default domain is set to <app-name> You can use this URL to visit the website.


Step 2: In the left-hand pane, click on Custom Domains.



Step 3: In the Custom Domains page, click on + Buy App Service domain if you want to buy an App Service domain or click on + Add custom domain if you have already purchased an App Service domain and you want to use it for this website.



Step 4: Search for the domain name you want to use with your WordPress website. If the domain name is unavailable, you will also see a list recommended and available domain names. Once you finalize on the domain name, click on Next: Contact information >


Step 5: Enter your contact details as required for domain name registration.



Step 6: Once the order is verified in the Review + Create tab, click on Create.



Step 7: You can see that the domain name is deployed. You can exit this Window.



Step 8: Go to the App Service page > Custom domains. You will see that your new domain name is listed here. You can secure your domain names by clicking on Add binding. Then Click on Validate and Add.






Step 9: [IMPORTANT] This step is very important if you are using Azure Front Door with your WordPress website or if you have a subdomain multisite set up. Go to Configuration Blade.

Add this Application Setting:












Step 10: Visit the website using your custom domain name.

II. Mapping an existing domain from an external registrar


Step 1: In the Custom domains page, click on + Add custom domain


Step 2: Select All other domain services as the Domain provider. Enter the existing domain name as the Domain. You will see two DNS records that you need to add in your domain’s DNS records. After adding, click on Validate.



Step 3: For demonstrating, I am using GoDaddy’s domain manager to add the DNS records.




Step 4: Once validated, you can now click on Add and the domain will be added to the list.



Step 5: We can add binding to the domain to make it secure.

III. Adding a subdomain to a custom domain


We can also add subdomains to our App Service. A subdomain can be used for subdomain multisite.


Step 1: In the Custom Domains page, click on + Add custom domain



Step 2: Select the App Service domain you need and select Subdomain as the Domain type. Enter the subdomain name and click Add.



Step 3: Now you can see that the subdomain has been added.



Note: In this example you will not be able to access your WordPress website using the new domain name , or the subdomain, or even using the default domain, because the WordPress website is configured with the custom domain: If you wish to use any of the other available domain names, you can edit the wp-config.php file and add the desired URL to these lines:


define('WP_HOME', ' <URL>');
define('WP_SITEURL', '<URL>');


This new domain and the subdomain can also be used to map to sites within your multisite network. Refer to [Subdomain multisite link]
