Requirements and limitations

Review this documentation if you are planning to use a private setup for Azure Postgres with your own private DNS.

The following limitations apply when using your own private DNS:
  • Only Azure’s private DNS zone is supported. Using an on-prem DNS is not supported.
  • The private DNS zone provided to Cloudera must have the name privatelink.postgres.database.azure.com in case of Flexible Server with Private Link and the name of the private DNS zone must ending with postgres.database.azure.com in case of Flexible Server with Delegated Subnet.
  • The private DNS zone must be in a subscription that is accessible to the service principal used by the Cloudera app-based credential; that is, the subscription where the private DNS zone is created must be in the same tenant where the service principal is located.
