How Do I Obtain the IP Address Corresponding to a Nacos Engine Domain Name?

The private address of Nacos is a domain name and cannot be directly resolved by CAE. When registering an application deployed by CAE with the new Nacos, you need to obtain the IP address corresponding to the domain name of the Nacos engine and add environment variables.

Note: Ensure that CAE and Nacos are in the same VPC when registering an application deployed by CAE with Nacos.

Procedure

  1. Log in to CSE. Choose Registry/Configuration Center.
  2. Click the target Nacos instance. On the basic information page, obtain the Nacos Private IP and Virtual Private Cloud.

  3. Log in to DNS. Choose Private Zones.
  4. In the private network domain name list, filter nacos.cse.com and click the domain name of the VPC obtained in 2.

  5. On the Record Sets page, select the private IP address in 2 to obtain the IP address corresponding to the domain name.
  6. Log in to CAE.
  7. On the Component Configurations page, configure the environment variable.
