Tutorial: Deploying the External DNS Operator on {product-title}

_attributes/attributes-openshift-dedicated.adoc :context: cloud-experts-external-dns

The External DNS Operator deploys and manages ExternalDNS to provide the name resolution for services and routes from the external DNS provider, like Amazon Route 53, to {product-title} clusters. In this tutorial, we will deploy and configure the External DNS Operator with a secondary ingress controller to manage DNS records in Amazon Route 53.

Important

The External DNS Operator does not support STS using IAM Roles for Service Accounts (IRSA) and uses long-lived Identity Access Management (IAM) credentials instead. This tutorial will be updated when the Operator supports STS.

Prerequisites

• A {product-title} cluster

  Note	{rosa-title} is not supported at this time.

• A user account with cluster-admin privileges

• The {oc-first}

• The Amazon Web Services (AWS) CLI (aws)

• A unique domain, such as apps.example.com

• An Amazon Route 53 public hosted zone for the above domain
