Find Latest AMI in AWS
We need to fetch the latest AMI ID for Ubuntu 22.04. This will be used as the base image to create a custom AMI by Packer.
Fetching AMI ID
Create a class called Slice. This class is inside Python package called grid.

import boto3
from datetime import datetime
class Slice:
def __init__(self):
self.ec2 = boto3.client('ec2')
def get_latest_ami_id(self, source_ami_name, ami_owners):
response = self.ec2.describe_images(
Filters=[
{
'Name': 'name',
'Values': [source_ami_name]
},
{
'Name': 'virtualization-type',
'Values': ['hvm']
}
],
Owners=ami_owners
)
if response['Images']:
latest_image = max(response['Images'], key=lambda x: x['CreationDate'])
creation_date = datetime.strptime(latest_image['CreationDate'], "%Y-%m-%dT%H:%M:%S.%fZ")
formatted_date = creation_date.strftime("%Y-%m-%d")
return latest_image['ImageId'], formatted_date
else:
return None, NoneCreate a Test Program
We will print the AMI ID and the creation date so that we can verify it manually from the AWS console. Create test_hive.py with:
from grid.slice import Slice
wafer = Slice()
source_ami_name = "ubuntu/images/*ubuntu-jammy-22.04-amd64-server-*"
ami_owners = ["099720109477"]
latest_ami_id, creation_date = wafer.get_latest_ami_id(source_ami_name, ami_owners)
if latest_ami_id:
print(f"Latest AMI ID: {latest_ami_id}")
print(f"AMI Creation Date: {creation_date}")
else:
print("No matching AMI found.")Run the Program
Output:
Latest AMI ID: ami-053053586808c3e70
AMI Creation Date: 2024-03-26You can also use Ansible playbook as discussed in Latest AMI for this task.
