Hi,
When you register the debug task you are not only handed back the
printed string but a dictionary containing information about the task
execution.
https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#registering-variables
What goes wrong is that in your code you are trying to subtract a
dictionary (date_earlier) from a string.
Take a look at the below example and I think things will become clearer:
user@dev:~/code/snippets$ cat register.yml
#!/usr/bin/ansible-playbook
---
- hosts: localhost
gather_facts: false
vars:
test: thisisastring
tasks:
- debug:
msg: "{{ test[:10] }}"
register: registered_var
- debug:
var: registered_var
user@dev:~/code/snippets$ ./register.yml
PLAY [localhost]
******************************************************************************
TASK [debug]
**********************************************************************************
ok: [localhost] => {
"msg": "thisisastr"
}
TASK [debug]
**********************************************************************************
ok: [localhost] => {
"registered_var": {
"changed": false,
"failed": false,
"msg": "thisisastr"
}
}
PLAY RECAP
************************************************************************************
localhost : ok=2 changed=0 unreachable=0
failed=0 skipped=0 rescued=0 ignored=0
If you to create a new variable you should instead use the
ansible.builtin.set_fact module.

Hi, bit of an odd statement no?
I use Ansible with AWX to make use of the task scheduling amongst all
the other features.
This is just another use case to add to the list of many.
I think you may have misunderstood what I am trying to achieve.
This usecase is for a backup schedule.
I want to remove any AWS AMIs 2 days older than current date.

Really not sure why you are trying to use Ansible for this type of
workflow ?
Using Boto3 would be much better
.
import boto3
import datetime
LaunchAge = 30
def days_old(date):
date_obj = date.replace(tzinfo=None)
diff = datetime.datetime.now() - date_obj
return diff.days
ec2 = boto3.client('ec2')
instance = ec2.describe_instances()
for i in instance['Reservations']:
for instance in i["Instances"]:
instance_id = instance["InstanceId"]
LaunchDate = instance['LaunchTime']
day_old = days_old(LaunchDate) # Get Date from Launch
if day_old > LaunchAge:
response = ec2.stop_instances(InstanceIds=[instance_id])
print(response)

Anyone help me on this one please :)
I think I need to convert string to date but I cannot seem to
get it to work.
Cheers!

Thanks David
I have tried similar to the above but get a
templating error:
{
"msg": "Unexpected templating type error
occurred on ({{ ( (ansible_date_time.date -
date_earlier).total_seconds() / 3600 ) | int }}):
unsupported operand type(s) for -:
'AnsibleUnsafeText' and 'dict'",
"_ansible_no_log": false
}
Here is my code:
---
- hosts: localhost
gather_facts: true
tasks:
- name: Get AMI info
amazon.aws.ec2_ami_info:
aws_access_key: "{{
lookup('env','AWS_ACCESS_KEY_ID') }}"
aws_secret_key: "{{
lookup('env','AWS_SECRET_ACCESS_KEY') }}"
region: eu-west-1
filters:
"tag:Backup_Policy": 1
register: date_earlier
- name: Compare AMI date
debug:
msg: "{{ ( (ansible_date_time.date -
date_earlier).total_seconds() / 3600 ) | int }}"
Any help would be appreciated

Hi, would really appreciate some help if
possible.
I am using ec2_ami_info to capture the
creation date.
I register the output as ami_creation_date.
Output is: 2021-09-09
I would like to delete the AMI if it is 2
days older than now.
I've tried some code I've used in the past
but getting templating errors etc.
Using the latest release of AWX.
Would really appreciate it if someone can
help :)
thank you!
