AWSEC2ModifyInstanceAttributeRequest

Objective-C

@interface AWSEC2ModifyInstanceAttributeRequest

Swift

class AWSEC2ModifyInstanceAttributeRequest

  • The name of the attribute to modify.

    You can modify the following attributes only: disableApiTermination | instanceType | kernel | ramdisk | instanceInitiatedShutdownBehavior | blockDeviceMapping | userData | sourceDestCheck | groupSet | ebsOptimized | sriovNetSupport | enaSupport | nvmeSupport | disableApiStop | enclaveOptions

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2InstanceAttributeName attribute;

    Swift

    var attribute: AWSEC2InstanceAttributeName { get set }

  • Modifies the DeleteOnTermination attribute for volumes that are currently attached. The volume must be owned by the caller. If no value is specified for DeleteOnTermination, the default is true and the volume is deleted when the instance is terminated. You can’t modify the DeleteOnTermination attribute for volumes that are attached to Fargate tasks.

    To add instance store volumes to an Amazon EBS-backed instance, you must add them when you launch the instance. For more information, see Update the block device mapping when launching an instance in the Amazon EC2 User Guide.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<AWSEC2InstanceBlockDeviceMappingSpecification *> *_Nullable blockDeviceMappings;

    Swift

    var blockDeviceMappings: [AWSEC2InstanceBlockDeviceMappingSpecification]? { get set }

  • Indicates whether an instance is enabled for stop protection. For more information, see Enable stop protection for your instance.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeBooleanValue *_Nullable disableApiStop;

    Swift

    var disableApiStop: AWSEC2AttributeBooleanValue? { get set }

  • If the value is true, you can’t terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. You cannot use this parameter for Spot Instances.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeBooleanValue *_Nullable disableApiTermination;

    Swift

    var disableApiTermination: AWSEC2AttributeBooleanValue? { get set }

  • Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable dryRun;

    Swift

    var dryRun: NSNumber? { get set }

  • Specifies whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal EBS I/O performance. This optimization isn’t available with all instance types. Additional usage charges apply when using an EBS Optimized instance.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeBooleanValue *_Nullable ebsOptimized;

    Swift

    var ebsOptimized: AWSEC2AttributeBooleanValue? { get set }

  • Set to true to enable enhanced networking with ENA for the instance.

    This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeBooleanValue *_Nullable enaSupport;

    Swift

    var enaSupport: AWSEC2AttributeBooleanValue? { get set }

  • Replaces the security groups of the instance with the specified security groups. You must specify the ID of at least one security group, even if it’s just the default security group for the VPC.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable groups;

    Swift

    var groups: [String]? { get set }

  • The ID of the instance.

    Declaration

    Objective-C

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

    Swift

    var instanceId: String? { get set }

  • Specifies whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeValue *_Nullable instanceInitiatedShutdownBehavior;

    Swift

    var instanceInitiatedShutdownBehavior: AWSEC2AttributeValue? { get set }

  • Changes the instance type to the specified value. For more information, see Instance types in the Amazon EC2 User Guide. If the instance type is not valid, the error returned is InvalidInstanceAttributeValue.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeValue *_Nullable instanceType;

    Swift

    var instanceType: AWSEC2AttributeValue? { get set }

  • Changes the instance’s kernel to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeValue *_Nullable kernel;

    Swift

    var kernel: AWSEC2AttributeValue? { get set }

  • Changes the instance’s RAM disk to the specified value. We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeValue *_Nullable ramdisk;

    Swift

    var ramdisk: AWSEC2AttributeValue? { get set }

  • Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives. If the value is true, source/destination checks are enabled; otherwise, they are disabled. The default value is true. You must disable source/destination checks if the instance runs services such as network address translation, routing, or firewalls.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeBooleanValue *_Nullable sourceDestCheck;

    Swift

    var sourceDestCheck: AWSEC2AttributeBooleanValue? { get set }

  • Set to simple to enable enhanced networking with the Intel 82599 Virtual Function interface for the instance.

    There is no way to disable enhanced networking with the Intel 82599 Virtual Function interface at this time.

    This option is supported only for HVM instances. Specifying this option with a PV instance can make it unreachable.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2AttributeValue *_Nullable sriovNetSupport;

    Swift

    var sriovNetSupport: AWSEC2AttributeValue? { get set }

  • Changes the instance’s user data to the specified value. If you are using an Amazon Web Services SDK or command line tool, base64-encoding is performed for you, and you can load the text from a file. Otherwise, you must provide base64-encoded text.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2BlobAttributeValue *_Nullable userData;

    Swift

    var userData: AWSEC2BlobAttributeValue? { get set }

  • A new value for the attribute. Use only with the kernel, ramdisk, userData, disableApiTermination, or instanceInitiatedShutdownBehavior attribute.

    Declaration

    Objective-C

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

    Swift

    var value: String? { get set }
