Hi Zhenguo,

The spec looks prefect to me, thanks a lot for doing that.

The python-valenceclient is high priority of valence Pike release, and still undergoing right now. We plan to release the python binding library at first. Now you need a simple wrapper if you start coding right now.

Regards,
Lin.

Thanks Yang, Lin for the explanation!

The Valence flavor shows a good example for baremetal instances, we do need such a flavor :D

I will draft a spec for this, you can help to review later. Another question is whether the Valence client is ready to use or we need to wrap the REST API ourselves?

Hi Zhenguo,

Please checkout the latest valence api spec, current it support two ways to specify the arguments when composing node via valence api.
1. Specify flavor for composition -  Specify flavor uuid in ‘flavor_id’ field {flavor_id: flavor_uuid} besides the name and description fields. An example of request body shows as below.
  {‘name’: ‘new_node’,
   ‘description’: ‘test composition’,
   ‘flavor_id’: ‘fake_uuid’}

2. Specify every hardware details, like cpu, memory, local/remote drive, nic, in ‘properties’ field.
  {‘name’: ‘new_node’,
   ‘description’: ‘test composition’,
   ‘properties’: {‘processor’: {‘total_cores’:8,
                                                    ‘model’: ‘fale_model’},
                            ‘memore’: {‘capacity_mib’: 4096,
                                                  ‘type’: ‘DDR3’}}}
We will update user document to list all available parameters for node composition soon.

Subject: [openstack-dev] [mogan][valence] Valence integration

hi guys,

Here is a spec about Mogan and Valence integration[1], but before this happen, I would like to know what information needed when requesting to compose a node through Valence. From the API doc[2], I can only find name and description parameters, but seems like it's incorrect, I suppose that it should at least include cpus, ram, disk or maybe cpuinfo. We need to align with this before introducing a new flavor for both RSD nodes and generic nodes.
