Cloudpods Python 3 SDK

本仓库提供了访问Cloudpods API的Python 3 SDK以及基于该SDK的climc客户端代码。

命令行使用方法

首先准备rc文件，内容如下(密码认证)：

export OS_USERNAME=sysadmin
export OS_PASSWORD=MXX2VKe067jtD
export OS_PROJECT_NAME=system
export OS_DOMAIN_NAME=Default
export OS_AUTH_URL=http://10.68.22.1:5000/v3
export OS_REGION_NAME=LocalTest

或aksk认证rc文件:

export OS_AUTH_URL=http://10.68.22.1:5000/v3
export OS_ACCESS_KEY=355270364e0a46eb84429e5ffa043842
export OS_SECRET_KEY=cktuREpGUnVrcjRNeGp0UlZQMmJaRjI4OVQ4UUdLanE=
export OS_REGION_NAME=LocalTest
export YUNION_INSECURE=true

首先source该rc文件，然后执行climc，例如：

$ source ~/rc_admin
$ climc server-list # 列出主机
$ climc image-list # 列出模板
$ climc server-create --disk <image_id> --disk 40g --mem 2g --ncpu 2 --allow-delete test --hypervisor esxi # 以模板 image_id 创建主机，数据盘40g，内存2g，虚拟CPU 2核，允许删除，机器名称test，虚拟化平台为esxi (VMWare)

SDK调用方法

首先安装yunionclient，执行

sudo python3 setup.py install

依赖安装包：

• argparse
• prettytable
• httplib2
• requests
• pycrypto>=2.6

首先，需要认证初始化client实例：

可以使用用户名和密码认证

import yunionclient.api.client

desc = {
    'project_name': 'system',
    'project_id': None,
    'args': (
        'https://nn.nnn.nnn.nnn:30357/v3',  # auth_url
        'sysadmin',                         # username
        'pppppppppppppppp',                 # password
        None,                               # domain
    ),
    'kwargs': {
        'region': 'YunionHQ',
        'zone': None,
        'insecure': True,
        'endpoint_type': 'publicURL',
    },
}

args = desc['args']
kwargs = desc['kwargs']
client = yunionclient.api.client.Client(*args, **kwargs)
project_name = desc.get('project_name')
project_id = desc.get('project_id')
if project_name is not None or project_id is not None:
    client.set_project(project_name=project_name, project_id=project_id)

也可以使用Access Key/Secret认证：

client = yunionclient.api.client.Client(
    'https://nn.nnn.nnn.nnn:30500/v3',
    region='YunionHQ',
    endpoint_type='publicURL',
    insecure=True,
)
client.authenticate_by_access_key('355270364e0a46eb84429e5ffa043842', 'cktuREpGUnVrcjRNeGp0UlZQMmJaRjI4OVQ4UUdLanE=')

Access Key/Secret可以通过climc获取：

climc credential-create-aksk

初始化client之后，则可以调用client的各个资源实例来访问各个资源的API，例如，虚拟机使用client.guests，镜像使用 client.images。

client目前仅支持了部分资源，具体参考 yunionclient/api/client.py 中 client.init 方法的资源的初始化列表。如果您有需要使用的资源未支持的，可以给我们提issue或者自行添加。

一般来说，每个资源实例都实现了下列的一系列方法：

操作	方法	举例
创建资源	client..create(**kwargs)	client.guests.create(**kwargs)
获得资源列表	client..list(**filters)	client.guests.list(**{scope=system})
执行资源的操作	client..perform_class_action(action, **kwargs)	client.guests.perform_class_action('validate_create_data', **kwargs)
获取某个资源的详情	client..get(id)	client.guests.get(id)
获取某个资源的特定属性	client..get_spec(id, spec)	client.guests.get_spec(id, 'vnc')
更新资源的属性	client..update(id, **kwargs)	client.guests.update(id, **{name: 'new-name'})
执行某个资源的操作	client..perform_action(id, action, **kwargs)	client.guests.perform_action(id, 'start')
删除某个资源	client..delete(id)	client.guests.delete(id)

具体方法参数，可以参考API文档：https://www.cloudpods.org/zh/docs/swagger
