Operation

modify_instance_attribute async

modify_instance_attribute(input: ModifyInstanceAttributeInput, plugins: list[Plugin] | None = None) -> ModifyInstanceAttributeOutput

Modifies the specified attribute of the specified instance. You can specify only one attribute at a time.

Note: Using this action to change the security groups associated with an elastic network interface (ENI) attached to an instance can result in an error if the instance has more than one ENI. To change the security groups associated with an ENI attached to an instance that has multiple ENIs, we recommend that you use the ModifyNetworkInterfaceAttribute action.

To modify some attributes, the instance must be stopped. For more information, see Modify a stopped instance in the Amazon EC2 User Guide.

Parameters:

Name Type Description Default
input ModifyInstanceAttributeInput

An instance of ModifyInstanceAttributeInput.

required
plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.

None

Returns:

Type Description
ModifyInstanceAttributeOutput

An instance of ModifyInstanceAttributeOutput.

Input

ModifyInstanceAttributeInput dataclass

Bases: _SerdeShape

Dataclass for ModifyInstanceAttributeInput structure.

Attributes

attribute class-attribute instance-attribute
attribute: str | None = ...

The name of the attribute to modify.

Note

When changing the instance type: If the original instance type is configured for configurable bandwidth, and the desired instance type doesn't support configurable bandwidth, first set the existing bandwidth configuration to default using the ModifyInstanceNetworkPerformanceOptions operation.

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

block_device_mappings class-attribute instance-attribute
block_device_mappings: list[InstanceBlockDeviceMappingSpecification] | None = ...

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 Amazon Web Services-managed resources.

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.

disable_api_stop class-attribute instance-attribute
disable_api_stop: AttributeBooleanValue | None = ...

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

disable_api_termination class-attribute instance-attribute
disable_api_termination: AttributeBooleanValue | None = ...

Enable or disable termination protection for the instance. If the value is true, you can't terminate the instance using the Amazon EC2 console, command line interface, or API. You can't enable termination protection for Spot Instances.

dry_run class-attribute instance-attribute
dry_run: bool | None = ...

Checks whether you have the required permissions for the operation, 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.

ebs_optimized class-attribute instance-attribute
ebs_optimized: AttributeBooleanValue | None = ...

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.

ena_support class-attribute instance-attribute
ena_support: AttributeBooleanValue | None = ...

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.

enclave_options class-attribute instance-attribute
enclave_options: EnclaveOptionsRequest | None = ...

Enables or disables the instance for Amazon Web Services Nitro Enclaves. For more information, see the Amazon Web Services Nitro Enclaves User Guide.

groups class-attribute instance-attribute
groups: list[str] | None = ...

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.

instance_id class-attribute instance-attribute
instance_id: str | None = ...

The ID of the instance.

instance_initiated_shutdown_behavior class-attribute instance-attribute
instance_initiated_shutdown_behavior: AttributeValue | None = ...

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

instance_type class-attribute instance-attribute
instance_type: AttributeValue | None = ...

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.

kernel class-attribute instance-attribute
kernel: AttributeValue | None = ...

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.

ramdisk class-attribute instance-attribute
ramdisk: AttributeValue | None = ...

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.

source_dest_check class-attribute instance-attribute
source_dest_check: AttributeBooleanValue | None = ...

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.

sriov_net_support class-attribute instance-attribute
sriov_net_support: AttributeValue | None = ...

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.

user_data class-attribute instance-attribute
user_data: SecureBlobAttributeValue | None = ...

Changes the instance's user data to the specified value. User data must be base64-encoded. Depending on the tool or SDK that you're using, the base64-encoding might be performed for you. For more information, see Work with instance user data.

value class-attribute instance-attribute
value: str | None = ...

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

Output

ModifyInstanceAttributeOutput dataclass

Bases: _SerdeShape

Dataclass for ModifyInstanceAttributeOutput structure.

Attributes

response_metadata class-attribute instance-attribute
response_metadata: ResponseMetadata = ...

Metadata about the response that produced this output. Use this to recover the request identifiers a service's support team needs in order to investigate a call. Members of the metadata are individually optional.
