hi there,
openstack instances that have a cinder volume attached as their primary block device won't return any information regarding the image that has been used during their creation:
openstack server show -f shell -c image -c volumes_attached test1 image="" volumes_attached="id='c0650208-f39c-4427-a73b-e1aa88531016'"
vs.
openstack server show -f shell -c image -c volumes_attached test2 image="Ubuntu 20.04 LTS (5cf81857-0dba-497e-ad9a-23a88dd97506)" volumes_attached=""
as a result, this information won't be available in ansible inventories created with the relevant plugin¹ either … this is unfortunate, since i need to set certain variables for ansible based on the image resp. the operating system an instance uses.
now, the necessary information seems to be available as a volume's metadata:
openstack volume show -f shell -c volume_image_metadata c0650208-f39c-4427-a73b-e1aa88531016 volume_image_metadata="{'signature_verified': 'False', 'hw_rng_model': 'virtio', 'hypervisor_type': 'qemu', 'os_distro': 'centos', 'os_type': 'linux', 'image_id': '1572c62f-438c-4a70-be84-973fef0d3c77', 'image_name': 'CentOS 8', 'checksum': 'd89eb49f2c264d29225cecf2b6c83322', 'container_format': 'bare', 'disk_format': 'qcow2', 'min_disk': '10', 'min_ram': '1024', 'size': '716176896'}"
… would it be a good idea to extend openstacksdk to look for image_name in the volumes attached to an instance and use this value for the image key?
thank you very much & with kind regards, t.
