Error getting image information: %v

Error message

Error getting image information: %v

What it means

Thrown by includeBootVolumeOptions (invoked from RenderOpenstack) when t.Cloud.GetImage fails while resolving the image used to build the boot-from-volume block device mapping. When metadata marks the instance as boot-from-volume, kOps must fetch the image (ID + MinDiskGigabytes) from Glance; any API failure here aborts server creation before the Nova call. This is a wrapper around the underlying gophercloud image error.

Solutions

1. Verify the image exists: `openstack image list | grep <image>` and correct the image name/ID in the cluster spec
2. Confirm the glance endpoint is registered: `openstack endpoint list --service image`
3. Re-authenticate (check OS_* credentials / token expiry) and rerun `kops update cluster`
4. If the image is private, ensure the project has access or make it shared/public
5. Retry if the failure was a transient 5xx; check the cloud provider status page

Example fix

// before
image: my-custom-image-v1   # deleted from Glance
// after
image: my-custom-image-v2   # exists: `openstack image list --name my-custom-image-v2`

// resolve the image before entering boot-from-volume path
func resolveImage(t *openstack.OpenstackAPITarget, imageName string) error {
	_, err := t.Cloud.GetImage(imageName)
	if err != nil {
		return fmt.Errorf("image %q unresolvable via Glance: %w", imageName, err)
	}
	return nil
}

func isImageNotFound(err error) bool {
	var _, nf gophercloud.ErrDefault404
	return errors.As(err, &nf) || strings.Contains(err.Error(), "No image with a name or ID")
}

When it happens

Trigger: Cloud.GetImage(e.Image) errors during a boot-from-volume apply: image name not found in Glance, image ID invalid, 401 auth failure on the image service endpoint, Glance endpoint misconfigured/absent in the catalog, or transient 5xx from the image API.

Common situations: Cluster spec references an image name that was deleted or renamed in the region; typos in the image field; operating across regions where the image exists only elsewhere; Glance service endpoint not registered in Keystone catalog; expired token before the image lookup.
