 3. Set a public-facing DNS label to the service using the `service.beta.kubernetes.io/azure-dns-label-name` service annotation. This publishes a fully qualified domain name (FQDN) for your service using Azure's public DNS servers and top-level domain. The annotation value must be unique within the Azure location, so we recommend you use a sufficiently qualified label. Azure automatically appends a default suffix in the location you selected, such as `<location>.cloudapp.azure.com`, to the name you provide, creating the FQDN.
