boto3 request_spot_instances調用中的客戶端錯誤

Question

我正在呼吁啟動競價型實例。 我正在使用的代碼-

request_spot_instances(
            SpotPrice = str(price),
            ClientToken = client_token,
            InstanceCount = count,
            Type = 'one-time',
            ValidFrom = valid_from,
            ValidUntil = valid_until,
            LaunchGroup = '',
            AvailabilityZoneGroup = '',
            BlockDurationMinutes = 120,
            LaunchSpecification = {
                'ImageId': image_id,
                'KeyName': key_name,
                'SecurityGroups': security_groups,
                'UserData': user_data,
                'InstanceType': instance_type,
                'Placement' : placement,
                'BlockDeviceMappings': block_device_map,
                'SubnetId': subnet_id,
                'NetworkInterfaces': [
                    network_interface
                ],
                'IamInstanceProfile': iamprofile,
                'Monitoring': {
                    'Enabled': True
                }
            }
        )

valid_from和valid_until的值是-

valid_from = datetime.utcnow()
valid_until = datetime.utcnow() + timedelta(minutes=10) 

撥打電話時出現以下錯誤-

*** ClientError: An error occurred (InvalidTime) when calling the RequestSpotInstances operation: "Sun Dec 04 22:17:59 UTC 2016" is an invalid time

如何解決此錯誤？

Answer 1

這應該工作：

valid_from = datetime.utcnow() + timedelta(seconds=3)
valid_until = valid_from + timedelta(minutes=10)

我遇到了同樣的問題，並得出結論， valid_from必須是“現在”或將來的某個地方。 通過將2-3秒添加到您的valid_from日期時間，它將起作用。
