working code:
import boto3
def lambda_handler(event, context):
ec2 = boto3.client('ec2')
# Get list of regions
regions = ec2.describe_regions().get('Regions',[] )
# Iterate over regions
for region in regions:
print("*************** Checking region -- %s " % region['RegionName'])
reg = region['RegionName']
print(reg)
Output:
*************** Checking region -- eu-north-1
eu-north-1
*************** Checking region -- ap-south-1
ap-south-1
*************** Checking region -- eu-west-3
eu-west-3
*************** Checking region -- eu-west-2
eu-west-2
*************** Checking region -- eu-west-1
its iterating and showing all the regions but my code is simply exiting with first iteration after i try to describe the resource details.

i have given all permissions to lambda role to access the resources. Can anyone help me what wrong i'm doing and how to know what is the error?
Your code iterated eu-north-1
and ap-south-1
successfully but then timed out after the default Lambda timeout of 3 seconds. You need to either make your code run faster or extend the Lambda timeout.
