AWS Lambda to stop ec2 instance with cron

• Create aws lambda function
• Attach IAM role as required

import boto3
region = 'ap-south-1'
instances = ['i-0e4e6863cd3da57b5']
ec2 = boto3.client('ec2', region_name=region)
def lambda_handler(event, context):
    ec2.stop_instances(InstanceIds=instances)
    print('stopped your instances: ' + str(instances))

• Create Cloudwatch event bus rule and attach it to lambda function
