Retrieving public dns of EC2 instance with BOTO3

Question

I\'m using ipython to get an understanding of Boto3 and interacting with EC2 instances. Here is the code I\'m using to create an instance:

import boto3

ec2 = bo         


        

Answer 1

import boto3
import pandas as pd
session = boto3.Session(profile_name='aws_dev')
dev_ec2_client = session.client('ec2')
response = dev_ec2_client.describe_instances()
df = pd.DataFrame(columns=['InstanceId', 'InstanceType', 'PrivateIpAddress','PublicDnsName'])
i = 0
for res in response['Reservations']:
    df.loc[i, 'InstanceId'] = res['Instances'][0]['InstanceId']
    df.loc[i, 'InstanceType'] = res['Instances'][0]['InstanceType']
    df.loc[i, 'PrivateIpAddress'] = res['Instances'][0]['PrivateIpAddress']
    df.loc[i, 'PublicDnsName'] = res['Instances'][0]['PublicDnsName']
    i += 1
print df

Note:

1. Change this profile with your AWS profile name profile_name='aws_dev'
2. This code is working for Python3
