Zend_Service_Amazon_Ec2: Amazon Machine Images (AMI) - Zend_Service
Amazon Machine Images (AMIs) are preconfigured with an ever-growing list of operating systems.
Example #1 Register an AMI with EC2
register Each AMI is associated with an unique ID
which is provided by the Amazon EC2 service through the RegisterImage
operation. During registration, Amazon EC2 retrieves the specified
image manifest from Amazon S3 and verifies that the image is owned by
the user registering the image.
register returns the imageId for the registered Image.
Example #2 Deregister an AMI with EC2
deregister, Deregisters an AMI. Once deregistered,
instances of the AMI can no longer be launched.
deregister returns boolean TRUE or
FALSE.
Example #3 Describe an AMI
describe 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.
| Name | Description |
|---|---|
public |
The owner of the AMI granted launch permissions for the AMI to the all group. All users have launch permissions for these AMIs. |
explicit |
The owner of the AMI granted launch permissions to a specific user. |
implicit |
A user has implicit launch permissions for all AMIs he or she owns. |
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 returned 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.
describe returns an array for all the images that match the critera
that was passed in. The array contains the imageId, imageLocation, imageState,
imageOwnerId, isPublic, architecture, imageType, kernelId, ramdiskId and platform.
Example #4 Modify Image Attributes
Modifies an attribute of an AMI
| Name | Description |
|---|---|
launchPermission |
Controls who has permission to launch the AMI. Launch permissions can be granted to specific users by adding userIds. To make the AMI public, add the all group. |
productCodes |
Associates a product code with AMIs. This allows developers to charge users for using AMIs. The user must be signed up for the product before they can launch the AMI. This is a write once attribute; after it is set, it cannot be changed or removed. |
modifyAttribute returns boolean TRUE or
FALSE.
Example #5 Reset an AMI Attribute
resetAttribute will reset the attribute of an AMI to
its default value. The productCodes attribute cannot be reset.
Example #6 Describe AMI Attribute
describeAttribute returns information about an attribute of an
AMI. Only one attribute can be specified per call. Currently only
launchPermission and productCodes are supported.
describeAttribute returns an array with the value of the attribute
that was requested.
