我们在博客中能够知道 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
为此我想看看是否能通过API 创建这种instance
通过查看 官网中的开源API 能够看到
中有这样一个API：
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’.
这个API 中有同样參数 --availability-zone
所以直接在使用这个API 的时候将默认參数 None 替换成你想定向的那个计算节点名就Ok了！
