How to create an Ec2 instance using Python boto3

Question

I want to create an Ec2 instance using Python boto3?

Can anyone help me with the code?

Answer 1

You can use the following code, it worked for me perfectly.

import boto3
ec2 = boto3.resource('ec2')
instance = ec2.create_instances(
    ImageId = 'ami-009d6802948d06e52',
    MinCount = 1,
    MaxCount = 1,
    InstanceType = 't2.micro',
    KeyName = 'nabarupa',
    SubnetId = 'subnet-0yhg678990d56c277')
print (instance[0].id)

Hope this helps.

What happens if I do not mention a subnetID?

If you don't specify a subnet-id then it will create a EC2 in the default VPC.

Check if you have all the required access. Your IAM user will require FullAccess to ec2 instances. Also allow programmatic access.

this step is very helpfull thankyou ,

but in lambda it showing following error:

Execution result: failed

{
  "errorMessage": "Handler 'lambda_handler' missing on module 'lambda_function'",
  "errorType": "Runtime.HandlerNotFound"
}

but ec2 is creating but showing above msg..please kindly help

---

You need to define a lambda_handler function in your code. The code is missing the function named lambda_handler.

Hi@parvathi konda,

I think there is a problem with your AWS credentials. Check your credentials properly.
