我正在尝试使用 boto 获取所有正在运行的实例，因此：

import boto
conn = boto.connect_ec2(aws_access_key_id='...',aws_secret_access_key='...')
conn.get_all_instances();

但是虽然我确实有一个正在运行的实例，但我得到了一个空列表。

将调试提升到 2 时，我可以看到以下内容：

[DEBUG]:validating server certificate: hostname=ec2.us-east-1.amazonaws.com, certificate hosts=['ec2.us-east-1.amazonaws.com', 'ec2.amazon...

提前谢谢大家

一种快速获取区域中当前正在运行的实例的方法

import boto.ec2
ec2_connection = boto.ec2.connect_to_region(region, aws_access_key_id=AWS_ACCESS_KEY_ID, aws_secret_access_key=AWS_SECRET_ACCESS_KEY)
instances = ec2_connection.get_only_instances(filters={'instance-state-name': 'running'})

这将返回一个 boto.ec2.instance.Instance 列表

boto API 文档 - get_only_instances

为避免混淆，最好指定要连接的区域，而不是依赖默认值 us-east-1。尝试这个：

>>> import boto
>>> import boto.ec2
>>> region = boto.ec2.get_region('us-west-1', aws_access_key_id=access_key, aws_secret_access_key=secret_key)
>>> print region
RegionInfo:us-west-1
>>> conn = boto.connect_ec2(aws_access_key_id=access_key,aws_secret_access_key=secret_key,region=region)
>>> conn.get_all_instances()
[Reservation:r-xxxx, Reservation:r-xxxx]
