You can install a cluster with a domain name server (DNS) solution that you manage instead of the default cluster-provisioned DNS solution. As a result, you can manage the API and Ingress DNS records in your own system rather than adding the records to the DNS of the cloud. For example, your organization's security policies might not allow the use of public DNS services such as Google Cloud DNS. In such scenarios, you can use your own DNS service to bypass the public DNS service and manage your own DNS for the IP addresses of the API and Ingress services.
7+
8+
If you enable user-managed DNS during installation, the installation program provisions DNS records for the API and Ingress services only within the cluster. To ensure access from outside the cluster, you must provision the DNS records in an external DNS service of your choice for the API and Ingress services after installation.
