Network.AWS.AutoScaling.UpdateAutoScalingGroup

Contents

Description

Updates the configuration for the specified Auto Scaling group.

To update an Auto Scaling group with a launch configuration with InstanceMonitoring set to False, you must first disable the collection of group metrics. Otherwise, you will get an error. If you have previously enabled the collection of group metrics, you can disable it using DisableMetricsCollection.

The new settings are registered upon the completion of this call. Any launch configuration settings take effect on any triggers after this call returns. Scaling activities that are currently in progress aren't affected.

Note the following:

  • If you specify a new value for MinSize without specifying a value for DesiredCapacity, and the new MinSize is larger than the current size of the group, we implicitly call SetDesiredCapacity to set the size of the group to the new value of MinSize.
  • If you specify a new value for MaxSize without specifying a value for DesiredCapacity, and the new MaxSize is smaller than the current size of the group, we implicitly call SetDesiredCapacity to set the size of the group to the new value of MaxSize.
  • All other optional parameters are left unchanged if not specified.

Synopsis

Creating a Request

updateAutoScalingGroup Source

Arguments

:: Text

uasgAutoScalingGroupName

-> UpdateAutoScalingGroup 

Creates a value of UpdateAutoScalingGroup with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

data UpdateAutoScalingGroup Source

See: updateAutoScalingGroup smart constructor.

Instances

Request Lenses

uasgTerminationPolicies :: Lens' UpdateAutoScalingGroup [Text] Source

A standalone termination policy or a list of termination policies used to select the instance to terminate. The policies are executed in the order that they are listed.

For more information, see Controlling Which Instances Auto Scaling Terminates During Scale In in the Auto Scaling Developer Guide.

uasgHealthCheckGracePeriod :: Lens' UpdateAutoScalingGroup (Maybe Int) Source

The amount of time, in seconds, that Auto Scaling waits before checking the health status of an EC2 instance that has come into service. The default is 300.

For more information, see Health Checks in the Auto Scaling Developer Guide.

uasgNewInstancesProtectedFromScaleIn :: Lens' UpdateAutoScalingGroup (Maybe Bool) Source

Indicates whether newly launched instances are protected from termination by Auto Scaling when scaling in.

uasgVPCZoneIdentifier :: Lens' UpdateAutoScalingGroup (Maybe Text) Source

The ID of the subnet, if you are launching into a VPC. You can specify several subnets in a comma-separated list.

When you specify VPCZoneIdentifier with AvailabilityZones, ensure that the subnets' Availability Zones match the values you specify for AvailabilityZones.

For more information, see Launching Auto Scaling Instances in a VPC in the Auto Scaling Developer Guide.

uasgDefaultCooldown :: Lens' UpdateAutoScalingGroup (Maybe Int) Source

The amount of time, in seconds, after a scaling activity completes before another scaling activity can start. The default is 300.

For more information, see Auto Scaling Cooldowns in the Auto Scaling Developer Guide.

uasgMaxSize :: Lens' UpdateAutoScalingGroup (Maybe Int) Source

The maximum size of the Auto Scaling group.

uasgAvailabilityZones :: Lens' UpdateAutoScalingGroup (Maybe (NonEmpty Text)) Source

One or more Availability Zones for the group.

uasgDesiredCapacity :: Lens' UpdateAutoScalingGroup (Maybe Int) Source

The number of EC2 instances that should be running in the Auto Scaling group. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.

uasgMinSize :: Lens' UpdateAutoScalingGroup (Maybe Int) Source

The minimum size of the Auto Scaling group.

uasgLaunchConfigurationName :: Lens' UpdateAutoScalingGroup (Maybe Text) Source

The name of the launch configuration.

uasgHealthCheckType :: Lens' UpdateAutoScalingGroup (Maybe Text) Source

The service to use for the health checks. The valid values are EC2 and ELB.

uasgPlacementGroup :: Lens' UpdateAutoScalingGroup (Maybe Text) Source

The name of the placement group into which you'll launch your instances, if any. For more information, see Placement Groups in the Amazon Elastic Compute Cloud User Guide.

uasgAutoScalingGroupName :: Lens' UpdateAutoScalingGroup Text Source

The name of the Auto Scaling group.

Destructuring the Response

updateAutoScalingGroupResponse :: UpdateAutoScalingGroupResponse Source

Creates a value of UpdateAutoScalingGroupResponse with the minimum fields required to make a request.

data UpdateAutoScalingGroupResponse Source

See: updateAutoScalingGroupResponse smart constructor.
