ansible date and time variable

[Om Prasad Surapu]

Hi Everyone,

I have an ansible playbook which will be used to take AMI snapshot of EC2 instance every month in a year.

Now i got a new requirement that snapshot should not be taken for every month and it should for 3 months once. I checked ansible_date_time but did not see the logic to take every 3 months. It has just day, month and yearly like ansible_date_time.month. 

here is my playbook (variable calls from template). Is there any way to take snapshot for every 3 months. It would be grateful if anyone could answer.

------------------------

- hosts: localhost
  connection: local

  vars:
    - ami_instance_id: null
    - ami_date: "{{ ansible_date_time.month }}{{ ansible_date_time.year }}"
    - ami_name: null
    - ami_service: null
  tasks:
    - name: create AMI
      ec2_ami:
        instance_id: "{{ ami_instance_id }}"
        wait: yes
        name: "{{ ami_name }}_{{ ami_date }}"
        region: us-east-1
        tags:
          Name: "{{ ami_name }}_{{ ami_date }}"
          Service: "{{ ami_service }}"
      register: instance

    - debug: var=instance

"Will be used" implies some existing mechanism to take snapshots.
The playbook you mentioned below doesn't seem to have any scheduling.
So what is the mechanism? Cloudwatch? Cron? Manual action?

Can you please explain a bit better what you mean by "it should for 3
months once"?

Thanks for your reply.

it was actually scheduled with crontab on Ansible Tower. I found that there is an option to change the interval every 3 months.

Thanks,
