在 EC2 上将 shell 脚本添加到 lambda function

Question

I have a lambda function that boots a machine on EC2 triggered by a file uploaded on S3 bucket. I would like to run a shell command that is in that machine after the boot, but I failed to do so. Any thoughts of what I can do?

import boto3

region = 'us-east-1'
instances = ['i-079e6065f959e151a']

def lambda_handler(event, context):
    ec2 = boto3.client('ec2', region_name=region)
    ec2.start_instances(InstanceIds=instances)

Answer 1

On the Amazon EC2 instance, store your script in:

/var/lib/cloud/scripts/per-boot/

Any scripts in that directory will be automatically run each time that the instance boots (or 'Starts').

When the instance has finished its work, it should perform a shutdown with:

sudo shutdown now -h

This will return the instance to a Stopped state.
