Get a list of all images (but only ami, not aki or ari)

[Neverland]

Hello,

it is easy to get a list of all images in a region via:

liste_images = conn_region.get_all_images()

But this needs a lot of time because all images (ami, aki and ari) are
fetched.

Is it possible to fetch only the ami images?

Best Regards,
Christian

No, unfortunately the EC2 API provides no ability to filter the returned list on the server side.  The only option is to get all of the results and then filter on the client-side.

Hello,

when I try to get a list of all images in an EC2 region via
get_all_images() with boto 1.9b inside GAE, I have this error:

<unknown>:23781:38: unclosed token

I think the list of images at EC2 is too long and GAE stops fetching
it. With Eucalyptus (I have only 10 images there) it's no problem to
fetch the list of images.

Has anybody here an idea how to get around a problem?

I'm not having any problem getting the list outside of GAE.  However, the list is HUGE and there is no paging mechanism and no way to filter results on the server side so I can imagine that it might be hitting some limit in GAE.  If that's the case, I'm afraid I am not aware of any workarounds but perhaps some other GAE users will know of something.

It is definitively a GAE issue and not a boto problem.

In my oppinion it is also not a good idea of amazon lacking the

ability to filter the returned
list on the server side.

Stale post, but found in recent search.

Check out http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeImages.html for the filter options.

Using this filter, I was able to capture only the AMIs owned by my account:

    images = ec2_connection.get_all_images(
        filters={
            'image_type': 'machine',
            'owner_id': '123456789',
        },
    )

Without the owner_id filter, the returned count was 41,000+

Without the owner_id, there were 41,000+ amis returned.
