Description

Describes one or more of the images (AMIs, AKIs, and ARIs) available to you. Images available to you include public images, private images that you own, and private images owned by other AWS accounts but for which you have explicit launch permissions.

Note

Deregistered images are included in the returned results for an unspecified interval after deregistration.

JSON Syntax:

  {
    "Name": "string",

  }
  ...
]

--image-ids (list)

One or more image IDs.

Default: Describes all images available to you.

Syntax:

"string" "string" ...

--owners (list)

Filters the images by the owner. Specify an AWS account ID, self (owner is the sender of the request), or an AWS owner alias (valid values are amazon | aws-marketplace | microsoft ). Omitting this option returns all images for which you have launch permissions, regardless of ownership.

Syntax:

"string" "string" ...

--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 (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

Images -> (list)

Information about one or more images.

(structure)

Describes an image.

Architecture -> (string)

The architecture of the image.

CreationDate -> (string)

The date and time the image was created.

ImageId -> (string)

The ID of the AMI.

ImageLocation -> (string)

The location of the AMI.

ImageType -> (string)

The type of image.

Public -> (boolean)

Indicates whether the image has public launch permissions. The value is true if this image has public launch permissions or false if it has only implicit and explicit launch permissions.

KernelId -> (string)

The kernel associated with the image, if any. Only applicable for machine images.

OwnerId -> (string)

The AWS account ID of the image owner.

Platform -> (string)

The value is Windows for Windows AMIs; otherwise blank.

ProductCodes -> (list)

Any product codes associated with the AMI.

(structure)

Describes a product code.

ProductCodeId -> (string)

The product code.

ProductCodeType -> (string)

The type of product code.

RamdiskId -> (string)

The RAM disk associated with the image, if any. Only applicable for machine images.

State -> (string)

The current state of the AMI. If the state is available , the image is successfully registered and can be used to launch an instance.

BlockDeviceMappings -> (list)

Any block device mapping entries.

(structure)

Describes a block device mapping.

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.

Iops -> (integer)

The number of I/O operations per second (IOPS) that the volume supports. For io1 , this represents the number of IOPS that are provisioned for the volume. For gp2 , this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information about General Purpose SSD baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide .

Constraint: Range is 100-20000 IOPS for io1 volumes and 100-10000 IOPS for gp2 volumes.

Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create gp2 , st1 , sc1 , or standard volumes.

SnapshotId -> (string)

The ID of the snapshot.

VolumeSize -> (integer)

The size of the volume, in GiB.

Constraints: 1-16384 for General Purpose SSD (gp2 ), 4-16384 for Provisioned IOPS SSD (io1 ), 500-16384 for Throughput Optimized HDD (st1 ), 500-16384 for Cold HDD (sc1 ), and 1-1024 for Magnetic (standard ) volumes. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size.

Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.

VolumeType -> (string)

The volume type: gp2 , io1 , st1 , sc1 , or standard .

Default: standard

Encrypted -> (boolean)

Indicates whether the EBS volume is encrypted. Encrypted volumes can only be attached to instances that support Amazon EBS encryption.

If you are creating a volume from a snapshot, you cannot specify an encryption value. This is because only blank volumes can be encrypted on creation. If you are creating a snapshot from an existing EBS volume, you cannot specify an encryption value that differs from that of the EBS volume. We recommend that you omit the encryption value from the block device mappings when creating an image from an instance.

KmsKeyId -> (string)

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

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

NoDevice -> (string)

Suppresses the specified device included in the block device mapping of the AMI.

Description -> (string)

The description of the AMI that was provided during image creation.

EnaSupport -> (boolean)

Specifies whether enhanced networking with ENA is enabled.

Hypervisor -> (string)

The hypervisor type of the image.

ImageOwnerAlias -> (string)

The AWS account alias (for example, amazon , self ) or the AWS account ID of the AMI owner.

Name -> (string)

The name of the AMI that was provided during image creation.

RootDeviceName -> (string)

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

RootDeviceType -> (string)

The type of root device used by the AMI. The AMI can use an EBS volume or an instance store volume.

SriovNetSupport -> (string)

Specifies whether enhanced networking with the Intel 82599 Virtual Function interface is enabled.

StateReason -> (structure)

The reason for the state change.

Code -> (string)

The reason code for the state change.

Message -> (string)

The message for the state change.
