Use PutScheduledUpdateGroupAction with a CLI

Example 1: To add a scheduled action to an Auto Scaling group

This example adds the specified scheduled action to the specified Auto Scaling group.

aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-scheduled-action \
    --start-time "2023-05-12T08:00:00Z" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4

This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.

For more examples, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide.

Example 2: To specify a recurring schedule

This example creates a scheduled action to scale on a recurring schedule that is scheduled to execute at 00:30 hours on the first of January, June, and December every year.

aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-recurring-action \
    --recurrence "30 0 1 1,6,12 *" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4

This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.

For more examples, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide.
