Scheduling Spot Bid Requests

You can set up Auto Scaling to launch a certain number of instances at a specific time. This capability is useful if, for example, you want to take advantage of a window of time when prices historically are lower, or you want to terminate Spot Instances at a specific time.

We will use the Auto Scaling CLI command as-put-scheduled-update-group-action to set up a schedule. This is the basic syntax:

as-put-scheduled-update-group-action ScheduledActionName --auto-scaling-group value [--desired-capacity value] [--end-time value][--max-size value][--min-size value] [--recurrence value][--start-time value][--time value][General Options]

In this scenario, use the following values:

Your command should look similar to the following example:

as-put-scheduled-update-group-action as-spotbid-schedule --auto-scaling-group spotasg --desired-capacity 20 --start-time 2012-05-15T19:10:00Z --end-time 2012-05-15T19:15:00Z

You should get a confirmation like the following example:

OK-Put Scheduled Update Group Action

To check your scheduled action, run as-describe-scheduled-actions.

You will get information similar to the following example:

UPDATE-GROUP-ACTION spotasg as-spotbid-schedule 2012-05-15T19:10:00Z 20
