list ami's older than x days/months - amazon-web-services

Question

Does anyone know if its possible to retrieve a list of EC2 AMIs older than x months(or days) using the ec2_ami_find module? So far I've got:
- name: ec2 find all
ec2_ami_find:
owner: self
region: us-west-1
sort: creationDate
sort_order: descending
register: ec2_ami
- name: test
set_fact:
date: "{{lookup('pipe','date +%Y%m%d%H%M%S -d \"180 day ago\"')}}"
msg: "{{ ec2_ami | json_query('results[?creationDate<`{{ date }}`]') }}"
However, this doesnt seem to work with me. Whatever I put in the date command(180 days, 1 day, 700 days), it retrieves the exact same list of AMI's for me.

Answer 1

It has to do with string interpolation and replacing the date variable in the set_fact directive. Here is an example, also I have used the ec2_ami_facts module instead of ec2_ami_find as ec2_ami_find would be deprecated soon.

- debug: var=filter_date
- set_fact:
filtered_ami: "{{ ec2_ami | json_query(\"images[?creation_date<=`\" + filter_date + \"`]\") }}"
- shell: echo "{{ filtered_ami | length }} {{ ec2_ami.images | length }}"

Please find the python script to list the AMIs older than X Days. Please do not forget to update your AWS credential profile value if you have multiple accounts as profiles=["default", "profile2"].
`
import boto3
from dateutil.parser import parse
import datetime
retention_day = "<addyour desired days here> eg. 30"
profiles = ["default"]
def days_old(date):
get_date_obj = parse(date)
date_obj = get_date_obj.replace(tzinfo=None)
diff = datetime.datetime.now() - date_obj
return diff.days
def get_ami_snap_list():
for profile in profiles:
session = boto3.Session(profile_name=profile)
ec2 = session.client('ec2')
Name=""
Description=""
amis = ec2.describe_images(Owners=[
'self'
])
for ami in amis['Images']:
try:
create_date = ami['CreationDate']
ami_id = ami['ImageId']
# print ami['ImageId'], ami['CreationDate']
day_old = days_old(create_date)
if day_old > retention_day:
# print(ami_id)
image = ec2.describe_images(ImageIds=[ami_id])
for img in image['Images']:
Name=img['Name']
Description=img['Description']
print(ami_id+",",Name+",",Description+",",profile)
except Exception as e:
print(ami_id + ",", Name + ",", Description + ",", profile)
get_ami_snap_list()
