The below is useful lambda function to delete EBS volumes older than ‘x’ days on all regions in the aws account.
import json
import os
import time
import subprocess
from datetime import datetime,date
import boto3
client = boto3.client('ec2')
awsRegions = client.describe_regions()['Regions']
def lambda_handler(event, context):
for region in awsRegions:
try:
owner_id = boto3.client('sts').get_caller_identity()['Account']
print ('#Method %s'%owner_id)
except Exception as e:
print ('Cant Connect to AWS %s' %e)
return
#Set which snapshot you want to delete number of days old
no_of_days = 30
formatter_string = "%Y-%m-%d"
current_date = time.strftime("%Y-%m-%d-%H-%M-%S")
try:
response_snapshot = client.describe_snapshots(OwnerIds=[owner_id,])
today_date = time.strftime("%Y-%m-%d")
datetime_object_today = datetime.strptime(today_date, formatter_string)
for snap in response_snapshot['Snapshots']:
try:
print (snap)
datetime_object_create = datetime.strptime(snap['StartTime'].strftime("%Y-%m-%d"), formatter_string)
if abs((datetime_object_today - datetime_object_create).days)>=no_of_days:
try:
print (datetime_object_today - datetime_object_create)
client.delete_snapshot(SnapshotId=snap['SnapshotId'])
print (snap['SnapshotId'] +' '+ 'Deleted')
except Exception as e:
print ('Error::%s'%e)
else:
print (datetime_object_today - datetime_object_create)
print (snap['SnapshotId'] +' '+ 'Not Deleted')
except Exception as e:
print ('Error::%s'%e)
except Exception as e:
print ('Error::%s'%e)
return
#lambda_handler(None,None)
Hope you enjoyed the post.
