Configuring an existing private DNS zone for a database

You can configure an existing Azure private DNS zone for your MySQL Flexi Server-based database to use in your CDE service. Alternatively, if you do not have an existing private DNS zone configured, the system can create a new private DNS zone for the database.

If all the following statements are true, the system uses the private DNS zone that you specify in the azure.database.privateDNSZoneId parameter for the database:

  • The privateNetwork.enabled parameter is set to true or false
  • The azure.database.privateDNSZoneId parameter is set

If all the following statements are true, the system creates and enables a new private DNS zone for the database:

  • The privateNetwork.enabled parameter is set to true or false
  • The azure.database.privateDNSZoneId parameter is not set

For the database, you can configure a private DNS zone regardless of whether the privateNetwork.enabled parameter is set to true or false. This is because the MySQL Flexi server implementation requires a private DNS zone.

For information on how to configure an existing private DNS zone for a database using the API, see Configuring an existing private DNS zone for a database and a Storage Account File Share using the API.

To configure an existing private DNS zone for a database, you need the full resource ID of the private DNS zone. To obtain the full resource ID, use the JSON view option in Azure > Private DNS Zones. Example for the full resource ID of a private DNS zone for a database:

/subscriptions/[***SUBSCRIPTIONID***]/resourceGroups/[***RESOURCEGROUP***]/providers/Microsoft.Network/privateDnsZones/privatelink.mysql.database.azure.com
To configure an existing private DNS zone for a database, specify the full resource ID of the private DNS zone.

To configure the Azure private DNS zone ID for the database, use the enable-cluster CDP command with the --azure-database-private-dns-zone-id flag.
