openstack 用nova API 指定 compute node 创建 instance

我们在博客中可以知道  能用命令行定向创建虚拟机到指定计算节点

nova boot --image fedora  --flavor 1  test1  --availability-zone nova:node-1

为此我想看看能否通过API  创建这样的instance

通过查看 官网中的开源API   可以看到

http://blog.csdn.net/qq_21398167/article/details/46530305

中有这样一个API：

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 – The Image to boot with. flavor – The 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 be 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 be exposed by the metadataserver this can be a file type object as well or astring. 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 this server. block_device_mapping_v2 – (optional extension) A dict of blockdevice mappings for this server. nics – (optional extension) an ordered list of nics to beadded to this server, with information aboutconnected networks, 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 are ‘AUTO’ or ‘MANUAL’.

所以直接在使用这个API 的时候将默认参数 None  替换成你想定向的那个计算节点名就Ok了！
