We can see in our blog that we can create a virtual machine to a specified compute node with command line orientation
http://blog.csdn.net/qq_21398167/article/details/46710175
Nova Boot--image Fedora--flavor 1 test1--availability-zone nova:node-1
So I want to see if I can create such a instance through the API.
By viewing the Open source API in the official website, you can see
http://blog.csdn.net/qq_21398167/article/details/46530305
There is an API in this:
-
- Create (
name,
image,
flavor,
meta=none,
files=none,
reservation _id=none,
min_count=none,
max_count=none,
security_groups=none,
userdata= None,
key_name=none,
availability_zone=none,
block_device_mapping=none, block_device_mapping_v2=none,
nics=none,
scheduler_hints=none,
config_drive= None,
disk_config=none,
**kwargs )
-
Create (boot) a new server.
| Parameters: |
- name –something to name the server.
- image , haven image to boot with.
- Flavor , haven flavor to boot onto.
- Meta –a dict of arbitrary key/value metadata to store for Thisserver. Both keys and values must be <=255 characters.
- files –a dict of files to Overrwrite on the server upon boot. Keys are file names (i.e./etc/passwd) and valuesare the file contents (either as a string or as Afile-like object ). A maximum of five entries is allowed,and each file must being 10k or less.
- reservation_id –a UUID for the set of servers being requested.
- Min_count – (optional extension) the minimum number ofservers to launch.
- Max_count – (optional extension) The maximum number ofservers to launch.
- security_groups –a List of security group names
- UserData –user data to pass to is exposed by the Metadataserver this can is a file type object as well or Astrin G.
- key_name – (optional extension) name of previously Createdkeypair to inject into the instance.
- Availability_zone –name of the availability zone for instanceplacement.
- block_device_mapping – (optional extension) A dict of blockdevice mappings for the this server.
- block_device_mapping_v2 – (optional extension) A dict of blockdevice mappings for the this server.
- NICs – (optional extension) an ordered list of NICs to beadded to this server, with information aboutconnected NE Tworks, fixed IPs, port etc.
- scheduler_hints – (optional extension) arbitrary key-value pairsspecified by the client to help boot an instance
- config_drive – (optional extension) value for config Driveeither boolean, or Volume-id
- disk_config – (optional extension) control how the disk ispartitioned when the server is created. PossibleValues is ' AUTO ' or ' MANUAL '.

This API has the same parameters--availability-zone
So just use this API to replace the default parameter None with the one you want to direct the compute node name is OK!
