StopFleetActions

Suspends certain types of activity in a fleet location. Currently, this operation is used to stop auto-scaling activity. For multi-location fleets, fleet actions are managed separately for each location.

Stopping fleet actions has several potential purposes. It allows you to temporarily stop auto-scaling activity but retain your scaling policies for use in the future. For multi-location fleets, you can set up fleet-wide auto-scaling, and then opt out of it for certain locations.

This operation can be used in the following ways:

To stop actions on instances in the fleet's home Region, provide a fleet ID and the type of actions to suspend.
To stop actions on instances in one of the fleet's remote locations, provide a fleet ID, a location name, and the type of actions to suspend.

If successful, GameLift no longer initiates scaling events except in response to manual changes using UpdateFleetCapacity. You can view a fleet's stopped actions using DescribeFleetAttributes or DescribeFleetLocationAttributes. Suspended activity can be restarted using StartFleetActions.

Examples

Stop auto-scaling activity in a fleet's remote location

In this example, we want to suspend all auto-scaling activity for a fleet's capacity in the remote location of ca-central-1. The fleet in question resides in the AWS Region us-west-2 (which is implicitly defined as our default Region). Once the policies are suspended, fleet capacity remains at the last "desired instances" setting unless fleet capacity is manually adjusted.

HTTP requests are authenticated using an AWS Signature Version 4 signature in the Authorization header field.
