以下是Lambda函数,我编写了获取Autoscaling组列表并打印它们。
import json
import boto3
import boto.ec2.autoscale
role = "arn:aws:iam::XXXXXXXXXX:role/lambda-autoshutdown-role"
regions = ["eu-central-1"]
autoscaling = boto3.client('autoscaling')
class App(object):
def __init__(self,RoleArn):
self.RoleArn = RoleArn
if self.RoleArn != "local":
sts_client = boto3.client('sts')
self.sts = sts_client.assume_role(
RoleArn=self.RoleArn,
RoleSessionName="lambda_poweroff")["Credentials"]
def get_resource(self,region="eu-central-1"):
if self.RoleArn == "local":
return boto3.resource(region_name=region)
else:
return boto.ec2.autoscale.connect_to_region(
region_name=region,
aws_access_key_id=self.sts['AccessKeyId'],
aws_secret_access_key=self.sts['SecretAccessKey'],)
def lambda_handler(event, context):
a = App(role)
for region in regions:
asgs = a.get_resource(region)
# locate all running instances
#autoscaling_groups_to_suspend = []
#for i in asgs:
# print asgs[i]
print '[%s]' % ', '.join(map(str, asgs))
此函数使用:boto.ec2.autoscale.connect_to_region
连接并返回对象。
但是当我尝试在AWS上部署它时,我收到以下错误:
Unable to import module 'lambda_function': No module named boto.ec2.autoscale
似乎AWS没有加载类boto.ec2.autoscale。
知道这里可能有什么问题吗?

您应该只使用:
import boto3
client = boto3.client('autoscaling')
参考:http://boto3.readthedocs.io/en/latest/reference/services/autoscaling.html

我正在尝试用s3做同样的事情。我需要boto.s3.connect_to_region(),但我得到了同样的错误。可能在lambda依赖项中导入boto模块可能会解决问题。否则,我们可能必须使用boto3.client并解析json响应以获取适当的值。

对于寻找答案的人,以下Lambda代码获取所有ASG的列表然后暂停它们(除了与regrex匹配的那些)
import json
import boto3
regions = ["eu-central-1"]
autoscaling = boto3.client('autoscaling')
def lambda_handler(event, context):
response = autoscaling.describe_auto_scaling_groups(MaxRecords=100)
#print response
#print(response['AutoScalingGroups'][0]['AutoScalingGroupName'])
autoscaling_group_to_suspend = []
for doc in response['AutoScalingGroups']:
response_parsed = doc['AutoScalingGroupName']
autoscaling_group_to_suspend.append(response_parsed)
#print autoscaling_group_to_suspend
import re
regex = re.compile(r'es-data-asg|consul|influxdb|vault|es-master')
filtered = filter(lambda i: not regex.search(i), autoscaling_group_to_suspend)
filtered = [i for i in autoscaling_group_to_suspend if not regex.search(i)]
print filtered
if len(filtered) > 0:
for x in filtered:
autoscaling.suspend_processes(AutoScalingGroupName=x)
