register-image

Description

Registers an AMI. When you’re creating an AMI, this is the final step you must complete before you can launch an instance from the AMI. For more information about creating AMIs, see Creating your own AMIs in the Amazon Elastic Compute Cloud User Guide .

Note

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don’t have to register the AMI yourself. We recommend that you always use CreateImage unless you have a specific reason to use RegisterImage.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

Register a snapshot of a root device volume

You can use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. You specify the snapshot using a block device mapping. You can’t set the encryption state of the volume using the block device mapping. If the snapshot is encrypted, or encryption by default is enabled, the root volume of an instance launched from the AMI is encrypted.

For more information, see Create a Linux AMI from a snapshot and Use encryption with Amazon EBS-backed AMIs in the Amazon Elastic Compute Cloud User Guide .

Amazon Web Services Marketplace product codes

If any snapshots have Amazon Web Services Marketplace product codes, they are copied to the new AMI.

Windows and some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the Amazon EC2 billing product code associated with an AMI to verify the subscription status for package updates. To create a new AMI for operating systems that require a billing product code, instead of registering the AMI, do the following to preserve the billing product code association:

  • Launch an instance from an existing AMI with that billing product code.

  • Customize the instance.

  • Create an AMI from the instance using CreateImage .

If you purchase a Reserved Instance to apply to an On-Demand Instance that was launched from an AMI with a billing product code, make sure that the Reserved Instance has the matching billing product code. If you purchase a Reserved Instance without the matching billing product code, the Reserved Instance will not be applied to the On-Demand Instance. For information about how to obtain the platform details and billing information of an AMI, see Understanding AMI billing in the Amazon Elastic Compute Cloud User Guide .

Options

--image-location (string)

The full path to your AMI manifest in Amazon S3 storage. The specified bucket must have the aws-exec-read canned access control list (ACL) to ensure that it can be accessed by Amazon EC2. For more information, see Canned ACLs in the Amazon S3 Service Developer Guide .

--architecture (string)

The architecture of the AMI.

Default: For Amazon EBS-backed AMIs, i386 . For instance store-backed AMIs, the architecture specified in the manifest file.

Possible values:

  • i386

  • x86_64

  • arm64

  • x86_64_mac

--block-device-mappings (list)

The block device mapping entries.

If you specify an Amazon EBS volume using the ID of an Amazon EBS snapshot, you can’t specify the encryption state of the volume.

If you create an AMI on an Outpost, then all backing snapshots must be on the same Outpost or in the Region of that Outpost. AMIs on an Outpost that include local snapshots can be used to launch instances on the same Outpost only. For more information, Amazon EBS local snapshots on Outposts in the Amazon Elastic Compute Cloud User Guide .

(structure)

Describes a block device mapping, which defines the EBS volumes and instance store volumes to attach to an instance at launch.

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.

Ebs -> (structure)

Parameters used to automatically set up EBS volumes when the instance is launched.

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 : 100-64,000 IOPS

For io1 and io2 volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System . Other instance families guarantee performance up to 32,000 IOPS.

This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for gp2 , st1 , sc1 , or standard volumes.

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 volumes sizes for each volume type:

  • gp2 and gp3 :1-16,384

  • io1 and io2 : 4-16,384

  • st1 and sc1 : 125-16,384

  • standard : 1-1,024

VolumeType -> (string)

The volume type. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide . If the volume type is io1 or io2 , you must specify the IOPS that the volume supports.

KmsKeyId -> (string)

Identifier (key ID, key alias, ID ARN, or alias ARN) for a customer managed CMK under which the EBS volume is encrypted.

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 only supported on BlockDeviceMapping objects called by 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 EC2 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 .

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.

Shorthand Syntax:

DeviceName=string,VirtualName=string,Ebs={DeleteOnTermination=boolean,Iops=integer,SnapshotId=string,VolumeSize=integer,VolumeType=string,KmsKeyId=string,Throughput=integer,OutpostArn=string,Encrypted=boolean},NoDevice=string ...

--description (string)

A description for your 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 .

--ena-support | --no-ena-support (boolean)

Set to true to enable enhanced networking with ENA for the AMI and any instances that you launch from the AMI.

This option is supported only for HVM AMIs. Specifying this option with a PV AMI can make instances launched from the AMI unreachable.

--kernel-id (string)

The ID of the kernel.

--name (string)

A name for your AMI.

Constraints: 3-128 alphanumeric characters, parentheses (()), square brackets ([]), spaces ( ), periods (.), slashes (/), dashes (-), single quotes (‘), at-signs (@), or underscores(_)

--billing-products (list)

The billing product codes. Your account must be authorized to specify billing product codes. Otherwise, you can use the Amazon Web Services Marketplace to bill for the use of an AMI.

(string)

Syntax:

"string" "string" ...

--ramdisk-id (string)

The ID of the RAM disk.

--root-device-name (string)

The device name of the root device volume (for example, /dev/sda1 ).

--sriov-net-support (string)

Set to simple to enable enhanced networking with the Intel 82599 Virtual Function interface for the AMI and any instances that you launch from the AMI.

There is no way to disable sriovNetSupport at this time.

This option is supported only for HVM AMIs. Specifying this option with a PV AMI can make instances launched from the AMI unreachable.

--virtualization-type (string)

The type of virtualization (hvm | paravirtual ).

Default: paravirtual

--boot-mode (string)

The boot mode of the AMI. For more information, see Boot modes in the Amazon Elastic Compute Cloud User Guide .

Possible values:

  • legacy-bios

  • uefi

--tpm-support (string)

Set to v2.0 to enable Trusted Platform Module (TPM) support. For more information, see NitroTPM in the Amazon Elastic Compute Cloud User Guide .

Possible values:

  • v2.0

--uefi-data (string)

Base64 representation of the non-volatile UEFI variable store. To retrieve the UEFI data, use the GetInstanceUefiData command. You can inspect and modify the UEFI data by using the python-uefivars tool on GitHub. For more information, see UEFI Secure Boot in the Amazon Elastic Compute Cloud User Guide .

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To register an AMI using a manifest file

The following register-image example registers an AMI using the specified manifest file in Amazon S3.

aws ec2 register-image \
    --name my-image \
    --image-location my-s3-bucket/myimage/image.manifest.xml
