In normal cases, the upstream and downstream storage devices of fully managed Flink deny access from external devices by default. Therefore, you must add the CIDR block of the vSwitch to which fully managed Flink belongs to the allowlist of your desired storage device.

  1. Log on to the Realtime Compute for Apache Flink console.
  2. On the Fully Managed Flink tab, find the desired workspace, click More in the Actions column, and then select Workspace Details.
  3. In the Workspace Details dialog box, view CIDR Block about the vSwitch to which fully managed Flink belongs.
  4. Add the CIDR block of the vSwitch to which fully managed Flink belongs to the allowlist of your desired storage device.
    For example, you must configure an allowlist for an ApsaraDB RDS for MySQL database. For more information, see Configure an IP address whitelist for an ApsaraDB RDS for MySQL instance.
    Note
    • If you add a vSwitch later, you must also add the CIDR block of the new vSwitch to the allowlist of the desired storage device.
    • If your vSwitch is not in the same zone as the upstream and downstream storage, the network can be connected after you add the CIDR block of the vSwitch to the allowlist.
