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

示例代码：

#!/usr/bin/env python3
# -*- encoding: utf-8 -*-
