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 isUnauthorizedOperation
.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 beimage
. -
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 besnapshot
. 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

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

<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.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/">
