+====
+Starting with {product-title} 4.14, the Custom Domain Operator is deprecated. To manage Ingress in {product-title} 4.14, use the Ingress Operator. The functionality is unchanged for {product-title} 4.13 and earlier versions.

 Configuring the xref:../applications/deployments/osd-config-custom-domains-applications.adoc[Custom Domain Operator] requires a wildcard CNAME DNS record in your Amazon Route 53 hosted zone. If you do not want to use a wildcard record, you can use the `External DNS` Operator to create individual entries for routes.
 
 Use this tutorial to deploy and configure the `External DNS` Operator with a custom domain in {product-title} (ROSA).
