Configuring Blacklist and Whitelist

Prerequisites

• You have created a microservice by referring to Creating a Microservice. After the microservice starts, the service instance is registered with the corresponding service based on the configurations in the YAML file. If the microservice is not created in advance or has been deleted, the microservice is automatically created when the service instance is registered.
• The blacklist and whitelist take effect only after public key authentication is enabled. For details, see Configuring Public Key Authentication.

Configuring Blacklist and Whitelist

1. Click the target engine.
2. Choose Microservice Governance.
   • For engines with security authentication disabled, go to 4.
   • For engines with security authentication enabled, if the login VDC user is the user imported in Importing an IAM Account, go to 4. For other users, go to 3.

3. In the displayed Security Authentication dialog box, enter the account name and password, and click OK.
   

   • If you connect to the ServiceComb engine for the first time, enter the account name root and the password entered when Creating a ServiceComb Engine.
   • For details about how to create an account, see Adding an Account.
