如何在openstack中使用python API 0.11.0设置图像元数据？

Question

I work with a DevStack -Grizzly installation. I add an image with metadata [see the code] using Openstack python API .

I use glance.images.create and provide metadata by properties argument. Unfortunately, the created image has no metadata (properties). image.get prints NONE .

import keystoneclient.v2_0.client as ksclient
import glanceclient

keystone = ksclient.Client(auth_url=credentials['auth-url'], username=credentials['username'],
                       password=credentials['password'], tenant_name=credentials['tenant'])

glance_endpoint = keystone.service_catalog.url_for(service_type='image',
                                                   endpoint_type='publicURL')

glance = glanceclient.Client('1',glance_endpoint, token=keystone.auth_token)
image_name="test-cirros"
image_file="cirros.img"

with open( image_file ) as fimage:
            image = glance.images.create(name=image_name, is_public=True, disk_format="qcow2", container_format="bare", data=fimage, properties =  {"aaaa": "13", "'bbbbbb": "12"} )
            print image.get() // prints NONE

Is there other way of setting image metadata?

Answer 1

Custom Properties != metadata, so the horizon does not display them and image.get returns empty hash.

To grab the metadata, I need to use nova client (API version 1.1 --- nova.images.get(image.id).metadata ):

 # ...
 from novaclient import client as novaclient

 # ...

 nova = novaclient.Client("1.1", auth_url=credentials['auth-url'], username=credentials['username'], api_key=credentials['password'], project_id=credentials['tenant'])

 # ...

 with open( image_file ) as fimage:
            image = glance.images.create(name=image_name, is_public=True, disk_format="qcow2", container_format="bare", data=fimage, properties =  {"aaaa": "13", "'bbbbbb": "12"} )

             print nova.images.get(image.id).metadata # prints the correct metadata
