Options

--attribute (string)

The AMI attribute.

Note : The blockDeviceMapping attribute is deprecated. Using this attribute returns the Client.AuthFailure error. To get information about the block device mappings for an AMI, use the DescribeImages action.

Possible values:

• description
• kernel
• ramdisk
• launchPermission
• productCodes
• blockDeviceMapping
• sriovNetSupport
• bootMode
• tpmSupport
• uefiData
• lastLaunchedTime
• imdsSupport
• deregistrationProtection

--image-id (string)

The ID of the AMI.

--dry-run | --no-dry-run (boolean)

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 .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

DeleteOnTermination -> (boolean)

Indicates whether the EBS volume is deleted on instance termination. For more information, see Preserving Amazon EBS volumes on instance termination in the Amazon EC2 User Guide .

Iops -> (integer)

The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type:

• gp3 : 3,000 - 16,000 IOPS
• io1 : 100 - 64,000 IOPS
• io2 : 100 - 256,000 IOPS

For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System . On other instances, you can achieve performance up to 32,000 IOPS.

This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS.

SnapshotId -> (string)

The ID of the snapshot.

VolumeSize -> (integer)

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. If you specify a snapshot, the default is the snapshot size. You can specify a volume size that is equal to or larger than the snapshot size.

The following are the supported sizes for each volume type:

• gp2 and gp3 : 1 - 16,384 GiB
• io1 : 4 - 16,384 GiB
• io2 : 4 - 65,536 GiB
• st1 and sc1 : 125 - 16,384 GiB
• standard : 1 - 1024 GiB

VolumeType -> (string)

The volume type. For more information, see Amazon EBS volume types in the Amazon EBS User Guide .

KmsKeyId -> (string)

Identifier (key ID, key alias, key ARN, or alias ARN) of the customer managed KMS key to use for EBS encryption.

This parameter is only supported on BlockDeviceMapping objects called by RunInstances , RequestSpotFleet , and RequestSpotInstances .

Throughput -> (integer)

The throughput that the volume supports, in MiB/s.

This parameter is valid only for gp3 volumes.

Valid Range: Minimum value of 125. Maximum value of 1000.

OutpostArn -> (string)

The ARN of the Outpost on which the snapshot is stored.

This parameter is not supported when using CreateImage .

Encrypted -> (boolean)

Indicates whether the encryption state of an EBS volume is changed while being restored from a backing snapshot. The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see Amazon EBS encryption in the Amazon EBS User Guide .

In no case can you remove encryption from an encrypted volume.

Encrypted volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types .

This parameter is not returned by DescribeImageAttribute .

For CreateImage and RegisterImage , whether you can include this parameter, and the allowed values differ depending on the type of block device mapping you are creating.

• If you are creating a block device mapping for a new (empty) volume , you can include this parameter, and specify either true for an encrypted volume, or false for an unencrypted volume. If you omit this parameter, it defaults to false (unencrypted).
• If you are creating a block device mapping from an existing encrypted or unencrypted snapshot , you must omit this parameter. If you include this parameter, the request will fail, regardless of the value that you specify.
• If you are creating a block device mapping from an existing unencrypted volume , you can include this parameter, but you must specify false . If you specify true , the request will fail. In this case, we recommend that you omit the parameter.
• If you are creating a block device mapping from an existing encrypted volume , you can include this parameter, and specify either true or false . However, if you specify false , the parameter is ignored and the block device mapping is always encrypted. In this case, we recommend that you omit the parameter.

NoDevice -> (string)

To omit the device from the block device mapping, specify an empty string. When this property is specified, the device is removed from the block device mapping regardless of the assigned value.

DeviceName -> (string)

The device name (for example, /dev/sdh or xvdh ).

VirtualName -> (string)

The virtual device name (ephemeral N). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1 . The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect.

Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.
