Instance failover

KakaoCloud provides both manual and automatic instance failover. This document describes how to manually fail over a running PostgreSQL instance.

Perform manual failover​

Notes when performing failover
  • Temporary service interruption may occur during failover, and the Standby instance switches to the Primary role.
  • To ensure that the switched instance operates normally, we recommend managing the resource status of Standby role instances, such as storage usage.
  • If there is no suitable Standby instance for failover, the Primary instance may restart and cause service interruption.
  • Manual failover is restricted in the Single state where there is only one instance.
  1. Go to the KakaoCloud console and navigate to Data Store > PostgreSQL.
  2. Under the Instance Group menu, select the PostgreSQL instance group where you want to perform the failover.
  3. Select the Instances tab and then select the [Manual failover] button.
  4. In the Manual failover pop-up window, select the [OK] button.
