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
