ec2-describe-images

Syntax

ec2-describe-images[ami_id ...] [-a] [-o owner ...] [-x user_id]

Description

Returns information about AMIs, AKIs, and ARIs available to the user. Information returned includes image type, product codes, architecture, and kernel and RAM disk IDs. Images available to the user include public images available for any user to launch, private images owned by the user making the request, and private images owned by other users for which the user has explicit launch permissions.

The list of AMIs returned can be modified by specifying AMI IDs, AMI owners, or users with launch permissions. If no options are specified, Amazon EC2 returns all AMIs for which the user has launch permissions.

If you specify one or more AMI IDs, only AMIs that have the specified IDs are returned. If you specify an invalid AMI ID, a fault is returned. If you specify an AMI ID for which you do not have access, it will not be included in the results.

If you specify one or more AMI owners, only AMIs from the specified owners and for which you have access are returned. The results can include the account IDs of the specified owners, amazon for AMIs owned by Amazon or self for AMIs that you own.

If you specify a list of executable users, only users that have launch permissions for the AMIs are returned. You can specify account IDs (if you own the AMI(s)), self for AMIs for which you own or have explicit permissions, or all for public AMIs.

	Note
	If you do not specify any optional parameters, Amazon EC2 returns images you own or images for which you have explicit access. Public images are not returned.

Machine images returned by this command include their kernel and RAM disk IDs.

Amazon EC2 returns a table that contains the following information:

A record type identifier ("IMAGE")
Image identifier
Manifest location
User identifier of the user that registered the image
Image status
Image visibility (public or private)
Product codes, if any, that are attached to the instance
Image architecture (i386 or x86_64)

ID of the kernel associated with the image (machine images only)
ID of the RAM disk associated with the image (machine images only)

Amazon EC2 displays errors on stderr.

Example

This example describes the ami-78a54011 AMI.

PROMPT> ec2-describe-images ami-78a54011
IMAGE ami-78a54011 powerdns/image.manifest.xml 495219933132 available private 774F4FF8 i386  machine aki-a2d732cb    ari-a3d732ca

This example describes the Amazon 64-bit AMI.

PROMPT> ec2-describe-images -o amazon | grep x86_64
IMAGE   ami-78a54034   ec2-public-images/fedora-core6-base-x86_64.manifest.xml
amazon   available   public x86_64  machine aki-a2d732cb    ari-a3d732ca

This example shows an AMI that runs Windows.

C:\> ec2-describe-images | findstr /i windows
IMAGE  ami-e6cd298f  Key2047/test.manifest.xml  720208972571  available  private  x86_64  machine  windows
