Ansible Cloud Module

[Shyam Yenna]

I am trying to create a role for aws vpc creation. one of the task is to create an elastic ip address and  associate that ip address to nat gateway instance. if i run multiple times playbook it is recreating elastic ip but i would like to find a viable solution to make it idempotent. Please can you let me know if any solution. I appreciate your feeedback.

ec2_eip and ec2_vpc_nat_gateway modules is been used.

Sample code:

- name:                         Create elastic ip for NAT Gateway

  ec2_eip:

    region:                     "{{ region }}"

    state:                      "present"

  register: ec2_eip

- name:                         Create NAT Gateway

  ec2_vpc_nat_gateway:

    state:                      "present"

    if_exist_do_not_create:     "true"

    allocation_id:              "{{ ec2_eip.allocation_id }}"

    region:                     "{{ region }}"

    

Thanks in  Advance
