Question

困惑，boto3 github project提到他们添加了对删除标记的支持。但是，当我在下面执行我的代码片段时，会引发以下异常：

ec2 = boto3.resource('ec2', region_name=aws_region)
ec2.delete_tags(Resources=[instance.id],Tags=[{"Key": non_compliant_tag_name}])

'ec2.ServiceResource' object has no attribute 'delete_tags'


$ pip show boto3
Name: boto3
Version: 1.4.4

我做错了什么？

Answer 1

delete_tags()方法应该在client对象而不是resource对象上调用：

import boto3
client = boto3.client('ec2', region_name='ap-southeast-2')
...
client.delete_tags(Resources=[instance.id],Tags=[{"Key": non_compliant_tag_name}])

Answer 2

您可以在Python中如下使用它

    import boto3

    reservations = ec2.describe_instances(
            Filters=[
                #{'Name': 'tag:Type', 'Values': ['management']},
            ]
        ).get(
            'Reservations', []
        )

        instances = sum(
            [
                [i for i in r['Instances']]
                for r in reservations
            ], [])

    for instance in instances:
       # Delete the tag 'baz' if it exists
       ec2.delete_tags(Resources=[instance['InstanceId']], Tags=[{"Key": "TAGNAME"}])
