CreateImage - Amazon Elastic Compute Cloud

CreateImage

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 Amazon 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 Create an Amazon EBS-backed Linux AMI in the Amazon Elastic Compute Cloud User Guide.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

BlockDeviceMapping.N

The block device mappings.

When using the CreateImage action:

  • You can't change the volume size using the VolumeSize parameter. If you want a different volume size, you must first change the volume size of the source instance.

  • You can't modify the encryption status of existing volumes or snapshots. To create an AMI with volumes or snapshots that have a different encryption status (for example, where the source volume and snapshots are unencrypted, and you want to create an AMI with encrypted volumes or snapshots), use the CopyImage action.

  • The only option that can be changed for existing mappings or snapshots is DeleteOnTermination.

Type: Array of BlockDeviceMapping objects

Required: No

Description

A description for the new image.

Type: String

Required: No

DryRun

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.

Type: Boolean

Required: No

InstanceId

The ID of the instance.

Type: String

Required: Yes

Name

A name for the new image.

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

Type: String

Required: Yes

NoReboot

Indicates whether or not the instance should be automatically rebooted before creating the image. Specify one of the following values:

  • true - The instance is not rebooted before creating the image. This creates crash-consistent snapshots that include only the data that has been written to the volumes at the time the snapshots are created. Buffered data and data in memory that has not yet been written to the volumes is not included in the snapshots.

  • false - The instance is rebooted before creating the image. This ensures that all buffered data and data in memory is written to the volumes before the snapshots are created.

Default: false

Type: Boolean

Required: No

TagSpecification.N

The tags to apply to the AMI and snapshots on creation. You can tag the AMI, the snapshots, or both.

  • To tag the AMI, the value for ResourceType must be image.

  • To tag the snapshots that are created of the root volume and of other Amazon EBS volumes that are attached to the instance, the value for ResourceType must be snapshot. The same tag is applied to all of the snapshots that are created.

If you specify other values for ResourceType, the request fails.

To tag an AMI or snapshot after it has been created, see CreateTags.

Type: Array of TagSpecification objects

Required: No

Response Elements

The following elements are returned by the service.

imageId

The ID of the new AMI.

Type: String

requestId

The ID of the request.

Type: String

Errors

Examples

Example 1

This example request creates an AMI from the specified instance.

Sample Request

https://ec2.amazonaws.com/?Action=CreateImage &Description=Standard+Web+Server+v1.0 &InstanceId=i-1234567890abcdef0 &Name=standard-web-server-v1.0 &AUTHPARAMS

Sample Response

<CreateImageResponse xmlns="http://ec2.amazonaws.com/doc/2016-11-15/"> <requestId>59dbff89-35bd-4eac-99ed-be587EXAMPLE</requestId> <imageId>ami-4fa54026</imageId> </CreateImageResponse>

Example 2

This example request creates an AMI from the specified instance, and sets the NoReboot parameter to true (the instance is not rebooted before the image is created).

Sample Request

https://ec2.amazonaws.com/?Action=CreateImage &Description=Standard+Web+Server+v1.0 &InstanceId=i-1234567890abcdef0 &Name=standard-web-server-v1.0 &NoReboot=true &AUTHPARAMS

Sample Response

<CreateImageResponse xmlns="http://ec2.amazonaws.com/doc/2016-11-15/"> <requestId>59dbff89-35bd-4eac-99ed-be587EXAMPLE</requestId> <imageId>ami-4fa54026</imageId> </CreateImageResponse>

Example 3

This example request creates an AMI from the specified instance, and tags on creation the AMI and the snapshots that are created of the root volume and of other Amazon EBS volumes that are attached to the instance. In this example, the tag that is applied to the AMI and the snapshots is the same, with a key of purpose and a value of test.

Sample Request

https://ec2.amazonaws.com/?Action=CreateImage &InstanceId=i-1234567890abcdef0 &TagSpecification.1.ResourceType=image &TagSpecification.1.Tag.1.Key=purpose &TagSpecification.1.Tag.1.Value=test &TagSpecification.2.ResourceType=snapshot &TagSpecification.2.Tag.1.Key=purpose &TagSpecification.2.Tag.1.Value=test &AUTHPARAMS

Sample Response

<CreateImageResponse xmlns="http://ec2.amazonaws.com/doc/2016-11-15/"> <requestId>59dbff89-35bd-4eac-99ed-be587EXAMPLE</requestId> <imageId>ami-4fa54026</imageId> </CreateImageResponse>
