What is BOTO3

The AWS SDK for Python (Boto3) is a Python package/module which provides a Python API for AWS infrastructure services. Using the SDK for Python, you can build applications on top of Amazon S3, Amazon EC2, Amazon DynamoDB, and many other AWS services.

With Boto3, developers can write Python scripts to create, configure, and manage AWS resources such as EC2 instances, S3 buckets, DynamoDB tables, Lambda functions, and more. It provides a comprehensive set of methods and classes for interacting with AWS services, allowing you to perform operations such as creating, deleting, updating, and retrieving information about resources.

Boto3 handles the low-level details of making requests to AWS services over HTTP, handling authentication, and parsing the responses. It simplifies the process of working with AWS APIs and provides an intuitive programming interface, allowing developers to focus on building their applications rather than dealing with the underlying infrastructure.

Boto3 is a powerful tool for Python developers who want to leverage the capabilities of AWS services in their applications. It is widely used for tasks such as infrastructure provisioning, data processing, automation, and building serverless applications on AWS.

How to get AWS EC2 instances using Python boto3

Steps to follow

• import boto3
• connect to EC2 resource
• Filter Running instances
• Get instance_id
• Get instance_type
• Get private_ip
• Get , {image_id},
• Get public_ip

Python Code – Describe/list EC2 instance

import boto3
ec2 = boto3.client('ec2')
reservations = ec2.describe_instances(Filters=[
    {
        "Name": "instance-state-name",
        "Values": ["running"],
    }
]).get("Reservations")


for reservation in reservations:
    for instance in reservation["Instances"]: ## Each reservation has an embedded Instances array that contains all EC2 instances in the reservation
        instance_id = instance["InstanceId"]
        instance_type = instance["InstanceType"]
        private_ip = instance["PrivateIpAddress"]
        image_id   = instance["ImageId"]
        public_ip = instance["PublicIpAddress"]
        print(f" {instance_id}, {instance_type}, {private_ip}, {image_id}, {public_ip} ")
