3. Create a file called external-dns-values.yaml and populate it with the following helm values:

   Code Block
   language yaml
   aws: zoneType: public domainFilters: - <eks_domain_zone_name from terraform output> policy: sync provider: aws txtOwnerId: <eks_domain_zone_id from terraform output> serviceAccount: create: false name: external-dns

4. Install the ExternalDNS helm chart:
