ScheduledAction

Source: src/AWS/ApplicationAutoScaling/ScheduledAction.ts

An Application Auto Scaling scheduled action — adjusts a scalable target’s minimum and/or maximum capacity on a one-time (at(...)) or recurring (cron(...) / rate(...)) schedule.

The action applies to the scalable target identified by the (serviceNamespace, resourceId, scalableDimension) triple, which must be registered (see ScalableTarget) before the action is created — pass the target’s outputs so deployment orders correctly.

Scheduling Capacity Changes

Scale Out for Business Hours

yield* ScheduledAction("BusinessHoursScaleOut", {
  serviceNamespace: target.serviceNamespace,
  resourceId: target.resourceId,
  scalableDimension: target.scalableDimension,
  schedule: "cron(0 8 ? * MON-FRI *)",
  timezone: "America/Los_Angeles",
  scalableTargetAction: { MinCapacity: 3, MaxCapacity: 10 },
});

One-Time Capacity Bump

yield* ScheduledAction("LaunchDayBump", {
  serviceNamespace: target.serviceNamespace,
  resourceId: target.resourceId,
  scalableDimension: target.scalableDimension,
  schedule: "at(2030-01-01T00:00:00)",
  scalableTargetAction: { MinCapacity: 5 },
});
