List AWS EC2 instance details with Name tag value

In this blog, we will look at how to execute Python script to get the AWS EC2 details like Name tag valie of the instance, Instance ID, Platform, Instance Type, State and its private IPv4 address. You will require Python 3.8 or above to run the the script successfully.

Setting up Boto3 Session and client

import boto3

# setup profile and region

profile = "default"

region = "us-east-1"

session = boto3.Session(profile_name=profile, region_name=region)

ec2_client = session.client('ec2')

response = ec2_client.describe_instances()

ec2_list = response['Reservations'] # Gather information about EC2

ec2_name = session.resource('ec2')

instances = ec2_name.instances.all() # This will help to retrieve Tags information

Now, let's print the header row.

# print header

print('Name, Instance ID, Platform, Instance Type, State, Private IPv4')

Following code will run and collect the information about EC2.  

for ec2 in ec2_list:

     

      ec2_describe = ec2['Instances']

     

      for ec2_details in ec2_describe:

         # Saving instance ID to the variable 

         ec2_id = ec2_details['InstanceId']

# Setting up EC2 platform type: windows or Linux

         ec2_platform = ec2_details['PlatformDetails']

         # Saving EC2 instance type to the variable

         ec2_type = ec2_details['InstanceType']

         # Saving EC2 state (Running/Stoped) to the variable

         ec2_state = ec2_details['State']

         # Saving EC2 private IPv4 address to the variable         

         ec2_privateip = ec2_details['PrivateIpAddress']

         

         instances = ec2_name.instances.filter(

            InstanceIds=[

                  ec2_details['InstanceId']

                  ],

         )

         # Fetching the Name tag value of the Instance ID

         for instance in instances:

            for tag in instance.tags:

               if tag["Key"] == 'Name':

                  instance_name = tag["Value"]

                  print(instance_name,', ', ec2_id,', ',ec2_platform,', ',ec2_type ,', ',ec2_state['Name'], ec2_privateip)

You can also include the other EC2 details such as Public IPv4, AMI ID, Keypair and launch time etc....

You can also use Tabulate module to format  your output to table or HTML format. To use to Tabulate module, please ensure that you have installed the module first. You can install the Tabulate module by running pip install tabulate command.
