Create a timer task

This topic describes how to create a timer task in the KubeSphere Virtualization (KSV) web console.

Prerequisites

The user that you use has been granted the permissions to manage timer tasks. Project administrators and operators can perform all operations on timer tasks, and project viewers can view only timer tasks. For more information about permissions, see Timer.

Procedure

1. Log in to the KSV web console.

3. In the left-side navigation pane, choose Timer > Timer Tasks.

4. On the Timer Tasks tab, click Create in the upper-right corner.

5. In the dialog box that appears, configure basic information for the timer task. The following table describes the parameters.

   Parameter	Description
