Getting the ID of an AMI created with Ansible

[Peter Palmieri]

I'm building an EC2 instance with Ansible, then creating an AMI from the instance. I'm sure I'm missing something here, but how do I get the ID of the newly created AMI? I've tried:

tasks:
- name: create an ami in us-east-1
  ec2_ami: wait=yes
           aws_access_key={{ ec2_access_key }}
           aws_secret_key={{ ec2_secret_key }}
           instance_id={{ item }}
           region={{ region1 }}
           name=data-mgmt-qa-006
  with_items: hostvars[inventory_hostname]['ansible_ec2_instance_id']
  register: ec2_ami_info

- debug: var=item
  with_items: ec2_ami_info.image_id 

and:

tasks:
- name: create an ami in us-east-1
  ec2_ami: wait=yes
           aws_access_key={{ ec2_access_key }}
           aws_secret_key={{ ec2_secret_key }}
           instance_id={{ item }}
           region={{ region1 }}
           name=data-mgmt-qa-006
  with_items: hostvars[inventory_hostname]['ansible_ec2_instance_id']
  register: instance

- debug: var=item
  with_items: instance.image_id

The latter 'register' is copied from the docs, but I'm not able to get the right with_items obviously.

The AMI is being created fine. Any suggestions would be much appreciated.

You should be able to just do:

- debug: var=instance.image_id

Which should print out the image's ID. If not, could you share what it does show?

Thanks for helping, it's much appreciated. 

I now have:

  tasks:

    - name: create an ami in us-east-1

      ec2_ami: wait=yes

               aws_access_key={{ ec2_access_key }}

               aws_secret_key={{ ec2_secret_key }}

               instance_id={{ item }}

               region={{ region1 }}

               name=some-name

      with_items: hostvars[inventory_hostname]['ansible_ec2_instance_id']

      register: instance

    - debug: var=instance.image_id

Which returns:

TASK: [create an ami in us-east-1] ******************************************** 

changed: [54.198.217.217] => (item=i-7c77c197)

TASK: [debug var=instance.image_id] ******************************************* 

ok: [54.198.217.217] => {

    "instance.image_id": "{{ instance.image_id }}"

}

instead of the actual image id. 

[Michael DeHaan]

Can you please share the output of:

- debug: var=instance

Thanks!

That shows:

TASK: [debug var=instance] **************************************************** 

ok: [54.90.128.104] => {

    "instance": {

        "changed": true, 

        "msg": "All items completed", 

        "results": [

            {

                "changed": true, 

                "image_id": "ami-be14b9d6", 

                "invocation": {

                    "module_args": "wait=yes aws_access_key=**** aws_secret_key=**** instance_id=i-393284d2 region=us-east-1 name=blah", 

                    "module_name": "ec2_ami"

                }, 

                "item": "i-393284d2", 

                "msg": "AMI creation operation complete", 

                "state": "available"

            }

        ]

    }

}

[Michael DeHaan]

In that case, looks like you want:

instance.results[0].image_id

Thank you very much, that did it.

How can I reference this in an ini file module? I'm trying to write the value of the ami id to a file, to be consumed by another process. This didn't work:

- ini_file: dest=ami.ini section=qa option=ami value={{ var=instance.results[0].image_id }}

I got:

TASK: [ini_file dest=ami.ini section=qa option=ami value={{ var=instance.results[0].image_id }}] *** 

failed: [54.166.40.120] => {"failed": true}

msg: this module requires key=value arguments (['dest=ami.ini', 'section=qa', 'option=ami', 'value={#', 'var=instance.results[0].image_id', '#}'])

[Michael DeHaan]

Take out the var=

{{ instance.results[0].image_id }}

[Peter Palmieri]

Sorry, I should have got that one on my own. Thank you again for your help. 

[Peter Palmieri]

Meant to add, Ansible is a huge boon to our infrastructure efforts. Thanks so much to the Ansible team for creating this tool. 

[Michael DeHaan]

Saying this collectively for hundreds of people here who have helped with things, and the rest of the team - you are welcome!!!
