How to set alias record set for cname

The CLI command creates the record without issue az network dns record-set cname set-record -g MyResourceGroup -z www.mysite.com -n MyRecordSet -c www.contoso.com

The problem seems to be that when the CNAME is created there’s no way to set the ALIAS RECORD SET flag to yes via the CLI?

Perhaps I need to execute a follow-up command?

@TeamDman --target-resource is used in record set. So it is available in az network dns record-set a create and az network dns record-set a update

I was able to create an alias record using the --target-resource flag. I’m creating A record rather than a CNAME. I arrived here from a Google search about how to create an Alias record at the domain apex. From the documentation, it looks like that flag is available when creating a CNAME too.

Here’s what I’m using (in Github Actions):

front_door_id=$(az network front-door show --name ${{ env.front_door_name }} --query id -o tsv) az network dns record-set a create --name "@" --zone-name ${{ env.domain_name }} --target-resource $front_door_id

It looks like you can do similar for a CNAME by using az network dns record-set cname create .... I put together the above commands based on this StackOverflow question: https://stackoverflow.com/questions/58316973/how-to-create-dns-a-record-usin-azure-cli-or-terraform
