需要释放所有区域中所有未使用boto3关联的弹性IP [英] Need to release all those elastic IP that are unassociated using boto3 in All regions
问题描述
我正在使用boto3和lamda释放未使用的弹性IP.在这里,我需要释放在我的AWS账户的所有区域中存在的所有IP.
I am using boto3 along with lamda to release the unused elastic IPs. Here I need to release all those IPs present in all regions of My AWS account.
def elastic_ips_cleanup():
client = boto3.client('ec2')
addresses_dict = client.describe_addresses()
for eip_dict in addresses_dict['Addresses']:
if "InstanceId" not in eip_dict:
print (eip_dict['PublicIp'] +
" doesn't have any instances associated, releasing")
client.release_address(AllocationId=eip_dict['AllocationId'])
我使用了上面的代码,但是它仅在执行lambda函数的特定区域中释放IP.
I used the above codes however it only releases the IP in a particular region where I am executing the lambda function.
预期输出:它应该释放所有区域中存在的所有未使用的弹性IP.
The expected output: It should release all the unused Elastic IPs present in all the Regions.
推荐答案
初始化的 boto3.client
仅在特定区域有效.默认情况下,您在 .aws/config
Once initialized boto3.client
works only in specific region. By default the one you have in your .aws/config
您可以遍历区域并通过可选参数 region_name = REGION_NAME
用特定区域重新初始化客户端.显然,然后重新运行您的函数.
You can loop through regions and reinitilize the client with specific region passing optional argument region_name=REGION_NAME
. Then rerun yuor function, apparently.
您可以使用:
import boto3
import logging
def elastic_ips_cleanup(region):
client = boto3.client('ec2', region_name=region)
# The rest of code you said you have tested already...
regions = [r['RegionName'] for r in boto3.client('ec2').describe_regions()['Regions']]
for region in regions:
logging.info(f"Cleaning {region}")
elastic_ips_cleanup(region)
