create-image¶

Description¶

Creates an Amazon EBS-backed AMI from an Amazon EBS-backed instance that is either running or stopped.

If you customized your instance with instance store volumes or EBS volumes in addition to the root device volume, the new AMI contains block device mapping information for those volumes. When you launch an instance from this new AMI, the instance automatically launches with those additional volumes.

For more information, see Creating Amazon EBS-Backed Linux AMIs in the Amazon Elastic Compute Cloud User Guide .

Options¶

--block-device-mappings (list)

The block device mappings. This parameter cannot be used to modify the encryption status of existing volumes or snapshots. To create an AMI with encrypted snapshots, use the CopyImage action.

(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. For more information, see Preserving Amazon EBS volumes on instance termination in the Amazon Elastic Compute Cloud User Guide.

Iops -> (integer)

The number of I/O operations per second (IOPS) that the volume supports. For io1 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. For more information, see Amazon EBS volume types in the Amazon Elastic Compute Cloud User Guide .

Constraints: Range is 100-16,000 IOPS for gp2 volumes and 100 to 64,000IOPS for io1 volumes in most Regions. Maximum io1 IOPS of 64,000 is guaranteed only on Nitro-based instances . Other instance families guarantee performance up to 32,000 IOPS. For more information, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide .

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.

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

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.

VolumeType -> (string)

The volume type. If you set the type to io1 , you must also specify the Iops parameter. If you set the type to gp2 , st1 , sc1 , or standard , you must omit the Iops parameter.

Default: gp2

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 .

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 Elastic Compute Cloud 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 .

NoDevice -> (string)

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

Shorthand Syntax:

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

JSON Syntax:

[
  {
    "DeviceName": "string",
    "VirtualName": "string",
    "Ebs": {
      "DeleteOnTermination": true|false,
      "Iops": integer,
      "SnapshotId": "string",
      "VolumeSize": integer,
      "VolumeType": "standard"|"io1"|"gp2"|"sc1"|"st1",
      "KmsKeyId": "string",
      "Encrypted": true|false
    },
    "NoDevice": "string"
  }
  ...
]

--description (string)

A description for the new image.

--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 .

--instance-id (string)

The ID of the instance.

--name (string)

A name for the new image.

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

--no-reboot | --reboot (boolean)

By default, Amazon EC2 attempts to shut down and reboot the instance before creating the image. If the ‘No Reboot’ option is set, Amazon EC2 doesn’t shut down the instance before creating the image. When this option is used, file system integrity on the created image can’t be guaranteed.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To create an AMI from an Amazon EBS-backed instance

This example creates an AMI from the specified instance.

Command:

aws ec2 create-image --instance-id i-1234567890abcdef0 --name "My server" --description "An AMI for my server"

Output:

{
    "ImageId": "ami-5731123e"
}

This example creates an AMI and sets the –no-reboot parameter, so that the instance is not rebooted before the image is created.

Command:

aws ec2 create-image --instance-id i-0b09a25c58929de26 --name "My server" --no-reboot

Output:

{
  "ImageId": "ami-1a2b3c4d"
}

To create an AMI using a block device mapping

Add the following parameter to your create-image command to add an Amazon EBS volume with the device name /dev/sdh and a volume size of 100:

--block-device-mappings "[{\"DeviceName\": \"/dev/sdh\",\"Ebs\":{\"VolumeSize\":100}}]"

Add the following parameter to your create-image command to add ephemeral1 as an instance store volume with the device name /dev/sdc:

--block-device-mappings "[{\"DeviceName\": \"/dev/sdc\",\"VirtualName\":\"ephemeral1\"}]"

Add the following parameter to your create-image command to omit a device included on the instance (for example, /dev/sdf):

--block-device-mappings "[{\"DeviceName\": \"/dev/sdf\",\"NoDevice\":\"\"}]"

Output¶

ImageId -> (string)

The ID of the new AMI.
