Securely connect Astro to resources running in other VNets or on-premises through a resolving service. Astronomer recommends using Domain Name System (DNS) forwarding as the most flexible and reliable solution. If you have a small number of records and immutable IP addresses, the Astronomer support team can create a Private zone with DNS records, pointed to your resources.
Use Domain Name System (DNS) forwarding to allow Astro to resolve DNS queries for resources running in other VPCs or on-premises. You have access to internal resources through private names. All changes in zone will be available for Astro environment immediately.To use this solution, make sure Astro can connect to the DNS server using a VNet or VHub peering connection and then submit a request to Astronomer support. With your request, include the following information:
  • The domain name for forwarding requests
  • The IP address of the DNS server where requests are forwarded

​
(Optional) Create an Airflow connection to confirm connectivity

After Astronomer support confirms that DNS forwarding was successfully set up, you can confirm that it works by creating an Airflow connection to a resource running in a VPC or on-premises. See Managing Connections.
