How to do it…

1. We can create an AMI of an existing EC2 Instance using an ec2_ami module. In this task we will be creating an AMI from the existing instance which, we created in one of the previous tasks. This task will require the instance id, the option to reboot the instance while creating the image, the name, and the tags for the image to be created as input parameters:

- name: Create AMI of Public Instance Created
  ec2_ami:
    aws_access_key: "{{ access_key }}"
    aws_secret_key: "{{ secret_key }}"
    region: "{{ aws_region }}"
    instance_id: "{{ item }}"
    wait: yes
    name: first_ami
    no_reboot: yes
    tags:
      Name: First AMI
  with_items:
    - "{{ ec2_public_instance.instance_ids }}"
  register: image

1. While creating an AMI for running an EC2 instance, we can select not to reboot that instance. If we are sure that the state of that instance will be consistent while creating AMI, we can use no_reboot as yes; otherwise the image created for that instance will not be in the same state we wanted it to be.
