I am deploying azure front door using bicep. It is erroring out
We couldn't create your custom domain. Another custom domain with the same host name already exists
we cannot delete the existing domains because we already added the _dnsauth record
is there a way around this?
Delete the existing domains because we already added the _dnsauth record?
Yes, we can delete existing domain associations first; later, we'll need to update TXT records on the provider's DNS side with the new domain. If we add without specifying a CNAME, we will receive this message.
A CNAME record for '.com' that points to '.azurefd.net' could not be found. Before you can associate a domain with this Front Door, you need to create a CNAME record with your DNS provider for 'chfrontdrtestdemo.com' that points to '.azurefd.net'.**
is there a way around this?
Yes, we have a workaround. First, we need to delete the existing domain association, and later we need to add a new CNAME entry. After that, we need to add the new domain association along with the txt entry mentioned below.
Step1:
Delete the existing domain association from Front Door
Step2:
Add new domain association and register the same with DNS provider..
NOTE:
During the domain validation process. If "Validation state" is "Pending" and when we click on that link, it turns into "Validate the custom domain." The panel gives the information for the DNS record required in order to validate the domain. It's a TXT record for _dnsauth.>.>.com with a specific record value. We should register this TXT record value at the DNS provider; otherwise, it won't be successful.

I acquired a new domain name in Azure (let's say mynewdomain.net), assigned it to my app service, bought a certificate also in Azure and made the bindings. Apparently both the domain and certificate are properly configured.
When I invoke the domain in any browser like https://mynewdomain.net, I get redirected to https://mynewdomain.net/mynewdomain.net, and of course fails.
The problem must be very simple, but I have no clue! Can anyone point me in the right direction here?
Thanks!
To create a CNAME mapping for the www subdomain, create two records: CNAME and TXT records.
After you add the CNAME and TXT records, the DNS records page looks like the following example:
To map an A record, you need the app's external IP address. You can find this IP address on the app's Custom Domains page in the Azure portal.
After the records are added, the DNS records page looks like the following example:
For more details, you could refer to this article about mapping an existing custom DNS name to Azure App Service.
In Azure, I have purchased a Custom Domain and the configuration has been done automatically - all good till now however the site is accessible only using: www.sitename.com
If I access it using http://sitename.com only, it is not working.
For info, I tried to remove the CNAME however didnt allow.
Suppose I dont want to use the wwww, how can I do ?
Thanks.
If you want to access your website with http://sitename.com, you have to create the A record and enable the A record mapping in the app. For how to map an A record, this doc is for your reference.
1.Copy the app's IP address
2.Create the A record
An A record to map to the app's IP address.
A TXT record to map to the app's default hostname.
3.Enable the A record mapping in the app
The custom domain you configured is not secured. You'd better click on "Add binding" to bind an existing custom SSL certificate to your app. For more details, you can refer to the doc.
The in the DNS for domain sitename.com the A record to is what make http://sitename.com works.
If you want http://www.sitename.com to work you HAVE TO have a www CNAME record.
I published my webforms site to Azure and now want to set up a subdomain to point to it.
In Azure, app service->Custom domains-> Custom Hostnames -> Add hostname
I selected A record for the Hostname record type.
However when I click Validate the Hostname record type reverts to CName
How do I validate an A record ?
[Update]
I see from this link that CName records are recommended.
Overwriting my choices when I click validate is a strange way of enforcing the recommendation though.
The system detects the record type automatically according to the hostname when you validate it. It's not recommended to choose the record type manually.
There are two steps to map a custom domain.
Create one record card in your DNS provider.
Add the hostname in Azure portal.
If you haven't created any record, what you have done is just to validate the availability of the hostname you input. Azure will remind you of the ownership as bellow.
If you have created an A record, and the record type reverted to CNAME after validation, which means you have specified a subdomain like www.contososo.com. The A record is only used to map root domain like contososo.com.
To map domain using A record, you need to create two records. Here's the example.
If you want to use CNAME or get more details, you can refer to the link you mentioned.
I'm having an issue with setting a custom wildcard domain on an Azure Website.
The azure website is demo.azurewebsites.net
And my custom domain is tenant1.demo.azurewebsites.net
I have done following steps : --
Step A:- Login into the portal.azure.com
Step B:- Then created zone with the following steps.
In this I filled all required information and select resource group as use existing. Because I have existing resource group. And click on create button.
C) After click on create button of above image it will show following image.
D) After that I crated record set. Please refer following image. I filled all information that required.
Name = *
Type = CNAME
TTL = 1
TTL unit = Hours
Alias = my existing domain
E) after that I created custom domain.
When I am going to create custom domain it show following error.
And my custom domain is tenant1.demo.azurewebsites.net
We can’t add subdomain to azurewebsites.net, because we are not the owner of azurewebsites.net.
Step B:- Then created zone with the following steps.
Until now, Azure doesn’t provide domain register service. Azure DNS Zone is used to host the DNS records for a particular domain. Azure DNS Service will answers DNS queries for records in the zone. It works as a name server. The prerequisites to use Azure DNS Zone is that you must be the owner of the domain. Please check the following note from Azure DNS Zone official document.
You do not have to own a domain name to create a DNS zone with that domain name in Azure DNS. However, you do need to own the domain to configure the Azure DNS name servers as the correct name servers for the domain name with the domain name registrar.
After you create a DNS Zone, to let the DNS record works, you also need to delegate your domain to Azure DNS by adding name server record in your domain register portal. Though you can add DNS record for demo.azurewebsites.net in your DNS zone as you mentioned in your post. But it won’t work until you have the right to configure the name server record in your domain register portal.
Once I have verified my domain in Azure with the CNAME record, can I remove the CNAME record safely from my DNS server without breaking anything?
You can safely delete the awverify records. Those are used only when validating the custom domain (while associating a new domain in the portal) and post that, they are not used so feel free to remove them.
