AWSAutoScalingStartInstanceRefreshType

Objective-C

@interface AWSAutoScalingStartInstanceRefreshType

Swift

class AWSAutoScalingStartInstanceRefreshType

  • The name of the Auto Scaling group.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable autoScalingGroupName;

    Swift

    var autoScalingGroupName: String? { get set }

  • The desired configuration. For example, the desired configuration can specify a new launch template or a new version of the current launch template.

    Once the instance refresh succeeds, Amazon EC2 Auto Scaling updates the settings of the Auto Scaling group to reflect the new desired configuration.

    When you specify a new launch template or a new version of the current launch template for your desired configuration, consider enabling the SkipMatching property in preferences. If it’s enabled, Amazon EC2 Auto Scaling skips replacing instances that already use the specified launch template and instance types. This can help you reduce the number of replacements that are required to apply updates.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingDesiredConfiguration *_Nullable desiredConfiguration;

    Swift

    var desiredConfiguration: AWSAutoScalingDesiredConfiguration? { get set }

  • Sets your preferences for the instance refresh so that it performs as expected when you start it. Includes the instance warmup time, the minimum and maximum healthy percentages, and the behaviors that you want Amazon EC2 Auto Scaling to use if instances that are in Standby state or protected from scale in are found. You can also choose to enable additional features, such as the following:

    • Auto rollback

    • Checkpoints

    • CloudWatch alarms

    • Skip matching

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingRefreshPreferences *_Nullable preferences;

    Swift

    var preferences: AWSAutoScalingRefreshPreferences? { get set }

  • The strategy to use for the instance refresh. The only valid value is Rolling.

    Declaration

    Objective-C

    @property (nonatomic) AWSAutoScalingRefreshStrategy strategy;

    Swift

    var strategy: AWSAutoScalingRefreshStrategy { get set }
