从快照创建CDS磁盘

使用以下代码可以从快照创建磁盘：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client, bcc_model

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = b'http://bcc.bj.baidubce.com'
    AK = b'ak'
    SK = b'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)


    resp = client.create_volume_with_snapshot_id(snapshot_id="s-er2Q****",  # 快照ID
                                                 charge_type='Postpaid',  # 支付方式
                                                 cluster_id="DC-jh5q****",  # 专属集群ID
                                                 purchase_count=2)  # 购买数量
    print (resp)

查询磁盘列表

使用以下代码查询所有的磁盘列表：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = b'http://bcc.bj.baidubce.com'
    AK = b'ak'
    SK = b'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)

    resp = client.list_volumes(instance_id="i-cVh8****",  # 磁盘挂载的实例ID
                               zone_name="cn-bj-c",  # 可用区
                               marker="v-3uIJ****",  # 起始卷ID
                               max_keys=10, # 返回列表的最大数量
                               cluster_id="DC-rWKx****") # CDS集群id
    print (resp)

查询磁盘详情

使用以下代码可以根据磁盘ID查询单个磁盘的详细信息：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = b'http://bcc.bj.baidubce.com'
    AK = b'ak'
    SK = b'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)

    resp = client.get_volume(volume_id='v-3uIJ****') # 指定磁盘ID
    print (resp)

挂载CDS磁盘

使用以下代码将磁盘挂载在指定的BCC实例下，注意CDS磁盘需要挂载在与其处在相同可用区下的BCC实例上。

只有磁盘状态为 Available 且实例状态为 Running 或 Stopped 时才允许挂载：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client, bcc_model

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = 'http://bcc.bj.baidubce.com'
    AK = 'ak'
    SK = 'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)
    # 设置要挂载的磁盘ID
    volume_id = 'v-***'
    # 设置要挂载的实例ID
    instance_id = 'i-***'
    resp = client.attach_volume(volume_id, instance_id)
    print(resp)

卸载CDS磁盘

使用以下代码将指定的磁盘从实例中卸载。

只有实例状态为 Running 或 Stopped 时，磁盘才可以执行此操作：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client, bcc_model

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = 'http://bcc.bj.baidubce.com'
    AK = 'ak'
    SK = 'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)
    
    # 设置要卸载的磁盘ID
    volume_id = 'v-***'
    # 设置所挂载的实例ID
    instance_id = 'i-***'
    resp = client.detach_volume(volume_id, instance_id)
    print(resp)

释放CDS磁盘

使用以下代码释放未挂载的CDS磁盘，系统盘不能释放：

磁盘释放后不可恢复。默认情况下，该磁盘的所有快照将保留，但会删除与磁盘的关联关系。

只有磁盘状态为 Available 或 Expired 或 Error 时才可以执行此操作。

def release_volume(self):

    #设置要释放的磁盘ID
    volume_id = 'your-choose-volume-id'

    self.assertEqual(

          type(self.client.release_volume(volume_id)), 

          baidubce.bce_response.BceResponse)

磁盘扩容

使用以下代码对磁盘进行扩容：

磁盘只能进行扩容操作，不支持缩容。
只有Available状态的磁盘，才能进行扩容操作。
只有磁盘状态为 Available 或 Expired 或 Error 时才可以执行此操作。
各磁盘类型可配容量范围详见磁盘性能。

# !/usr/bin/env python
# coding=utf-8
from baidubce.services.bcc import bcc_client
from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration


if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = b'http://bcc.bj.baidubce.com'
    AK = b'ak'
    SK = b'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)
    
    volume_id = "v-***"
    
    # 请求扩容磁盘，变更磁盘类型和大小
    response = client.resize_volume(volume_id=volume_id,             # 磁盘ID
                                    new_cds_size=50,                 # 扩容后磁盘大小, 单位为GB
                                    new_volume_type="cloud_hp1")     # 扩容后磁盘类型, 可取值见：https://cloud.baidu.com/doc/BCC/s/6jwvyo0q2#storagetype
    print(response)

回滚磁盘

使用以下代码用指定磁盘自身的快照回滚磁盘内容：

磁盘状态必须为 Available 才可以执行此操作。
指定 snapshotId 必须是由 volumeId 创建的快照。
若是回滚系统盘，实例状态必须为 Running 或 Stopped 才可以执行此操作。
回滚系统盘快照，自本次快照以来的系统盘数据将全部丢失，不可恢复：

from baidubce.auth.bce_credentials import BceCredentials from baidubce.bce_client_configuration import BceClientConfiguration from baidubce.services.bcc import bcc_client, bcc_model

if name == 'main': # 设置您的ak、sk和要访问的地域 HOST = b'http://bcc.bj.baidubce.com' AK = b'ak' SK = b'sk' # 设置默认配置 config = BceClientConfiguration(credentials=BceCredentials(AK, SK), endpoint=HOST) # 创建bcc client client = bcc_client.BccClient(config) volume_id = 'v-vG0z**' # 用于回滚指定磁盘的快照ID，必须为 volumeId 所创建的快照 snapshot_id = 's-HkbJ**' resp = client.rollback_volume(volume_id, snapshot_id) print (resp)

磁盘续费

使用以下代码可以实现磁盘续费。

磁盘扩缩容期间不能进行续费操作：

from baidubce.auth.bce_credentials import BceCredentials
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.services.bcc import bcc_client, bcc_model

if __name__ == '__main__':
    # 设置您的ak、sk和要访问的地域
    HOST = b'http://bcc.bj.baidubce.com'
    AK = b'ak'
    SK = b'sk'
    # 设置默认配置
    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)
    # 待续费磁盘ID
    volume_id = 'v-PGE6****'
    # 设置续费时长,目前只支持续费单位为月
    billing = bcc_model.Billing('Prepaid', 2)
    resp = client.purchase_reserved_volume(volume_id=volume_id, billing=billing)
    print (resp)

    config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
                                    endpoint=HOST)
    # 创建bcc client
    client = bcc_client.BccClient(config)
    # 待修改磁盘ID
    volume_id = 'v-vG0z****'
    # 设置磁盘新名称
    cds_name = 'new-cds-name'
    resp = client.modify_volume_Attribute(volume_id=volume_id, cds_name=cds_name)
    print (resp)

    volume_id = "v-***"
    post_paid_billing = bcc_model.Billing(paymentTiming='Prepaid',          # 预付费计费方式, 指定paymentTiming为Prepaid, 可不填
                                        reservationLength=3,              # 预付费时长, 单位为月时取值范围为1-9
                                        reservationTimeUnit='Month')       # 预付费时长单位，当前支持取值为Month

    # 请求将后付费磁盘变更计费方式为预付费
    response = client.modify_volume_charge_type(volume_id=volume_id,            # 磁盘ID
                                                billing=post_paid_billing)      # 计费方式

磁盘解绑标签

使用以下代码可以给指定磁盘解绑标签：

# !/usr/bin/env python
# coding=utf-8
