Auto Start & Stop EC2 Instance at a Specific Time Using AWS EventBridge by awsmasterchef

In this video we have created an EventBridge schedule that triggers an Lamba function which is responsible for start and stop of EC2 Instance

#aws #ec2 #awslambda

This is a great way to start / stop an EC2 instance. Thank you for this, however you should put the Lambda function in your video description to avoid people needing to manually type it out.

I have typed out the function here in case anyone needs it:

import boto3

def lambda_handler(event, context):
ec2 = boto3.client('ec2')
action = event['action']
instances = ec2.describe_instances()
instance_ids = [instance['InstanceId'] for reservation in instances['Reservations'] for instance in reservation['Instances']]
if action == 'start':
if instance_ids:

print('Starting instances;", instance_ids)
else:
print("No instances found to start")
elif action == 'stop':
if instance_ids:

print("Stopping instances:", instance_ids)
else:
print("No instances found to stop")
else:
print("Invalid action provided in the event")
