snapshot.wait_until_completed没有显示进度，也没有完成

Question

我有一个小函数负责创建快照，它工作正常;但我希望得到的进展，以及，但下面的功能并不能帮助我：

def call_creater(): 
    regions = ['eu-central-1'] 
    for region in regions: 
     ec2 = boto3.resource('ec2', region, aws_access_key_id=ACCESS_KEY, aws_secret_access_key=SECRET_KEY,) 
     snapshot = ec2.create_snapshot(VolumeId='vol-f9e7d220', Description='fra01-he-trial-ansible01') 
     print snapshot.id 

     get_all_snapshots = ec2.snapshots.filter(snap_id=['SnapshotIds']) 
     print get_all_snapshots 
     #snapshot.wait_until_completed() 
     print "STARTING TO CREATE :" 
     time.sleep(10) 
     snapshot.wait_until_completed(
      Filters=[ 
       { 
        'Name': 'progress' 
       } 
       ] 
     ) 
     print "snapshot ready" 

此抛出：

'Name': 'progress' 
    File "C:\Python27\lib\site-packages\boto3\resources\factory.py", line 368, in do_waiter 
    waiter(self, *args, **kwargs) 
    File "C:\Python27\lib\site-packages\boto3\resources\action.py", line 201, in __call__ 
    response = waiter.wait(**params) 
    File "C:\Python27\lib\site-packages\botocore\waiter.py", line 53, in wait 
    Waiter.wait(self, **kwargs) 
    File "C:\Python27\lib\site-packages\botocore\waiter.py", line 321, in wait 
    reason='Max attempts exceeded') 
botocore.exceptions.WaiterError: Waiter SnapshotCompleted failed: Max attempts exceeded 

虽然快照被创建，我不能够得到状态

Answer 1

wait_until_completed should wait for a maximum of about 10 minutes，这远远不够大的快照和reportedly it's returning faster even than that。由于这个功能似乎被破坏了，我建议写下你自己的服务员。
