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 version. 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 }

  • Set of preferences associated with the instance refresh request. If not provided, the default values are used.

    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.

    A rolling update helps you update your instances gradually. A rolling update can fail due to failed health checks or if instances are on standby or are protected from scale in. If the rolling update process fails, any instances that are replaced are not rolled back to their previous configuration.

    Declaration

    Objective-C

    @property (nonatomic) AWSAutoScalingRefreshStrategy strategy;

    Swift

    var strategy: AWSAutoScalingRefreshStrategy { get set }
