Question

我正在尝试使用Boto3创建AWS快照，但据我所知n个选项失败。

connection=ec2.connect_to_region('ap-southeast-1')
def Create_Snapshot(Source_volID):
    snapshot = connection.create_snapshot(Source_volID)
    while snapshot.status != 'completed':
        snapshot.update()
        print snapshot.status
        time.sleep(5)
        if snapshot.status == 'completed':
            connection.create_tags(Resources=[snapshot.id], Tags=[{'Key':'Name', 'Value':'uat3-gold-'}])
            return snapshot.id

这将返回错误：

Traceback (most recent call last):
File "/Users/py-projects/8.py", line 62, in <module>
print Create_Snapshot(Source_volID)
File "/Users/py-projects/8.py", line 47, in Create_Snapshot
connection.create_tags(Resources=[snapshot.id], Tags=[{'Key':'Name', 'Value':'uat3-sogpet-gold-'}])
TypeError: create_tags() got an unexpected keyword argument 'Resources'

还尝试了stackoverflow中提到的其他方式。

def Create_Snapshot(Source_volID):
    snapshot = connection.create_snapshot(
    VolumeId=Source_volID,
    Description='Gold volume copy',
    TagSpecifications=[
        {
            'ResourceType': 'snapshot',
            'Tags': [
                {
                    'Key': 'Name',
                    'Value': 'uat3-gold-'
                }
            ]
        },
    ]
    )
    while snapshot.status != 'completed':
        snapshot.update()
        print snapshot.status
        time.sleep(5)
        if snapshot.status == 'completed':
            connection.create_tags(Resources=[snapshot.id], Tags=[{'Key':'Name', 'Value':'uat3-sogpet-gold-'}])
            return snapshot.id

原因错误：

Number of snaps 0
No Snapshots present within 10 minutes
vol-0xxxxxxxxxxxxxxx
Traceback (most recent call last):
File "/Users/py-projects/8.py", line 76, in <module>
print Create_Snapshot(Source_volID)
File "/Users/py-projects/8.py", line 50, in 
Create_Snapshot
'Value': 'uat3-gold-'
TypeError: create_snapshot() got an unexpected keyword argument 'VolumeId'

我也在python3中尝试过，但是失败了。请给我一个线索，因为我坚持了两天。谢谢。

尝试这种方式。

session = boto3.Session(profile_name=profile, region_name=region)
client = session.client('ec2')
client.create_snapshot(
    Description='Gold volume copy',
    VolumeId=Source_volID,
    TagSpecifications=[
        {
            'ResourceType': 'snapshot',
            'Tags': [
                {
                    'Key': 'Name',
                    'Value': 'uat3-gold-'
                }
            ]
        }
    ]
)

create_tag（）在boto3中失败
