Trying to get aws instance id

[Christian Del Pino]

Hello,

I am having some difficulties trying to obtain the instance id for an ec2 instance that is being created. Here is what I have at the moment to create the ec2 instance:

### Create NAT Instance ###

- name: Launch NAT instance

  ec2:

    vpc_subnet_id: "{{ name_subnet.subnet.id }}"

    region: "{{ aws_region }}"

    keypair: "{{ keypair.key.name }}"

    group_id: "{{ natsecuritygroup.group_id }}"

    image: "{{ nat_aws_image }}"

    instance_type: "{{ nat_aws_instance_type }}"

    instance_tags:

      type: "nat"

      Name: "NAT"

    exact_count: 1

    count_tag:

      type: "nat"

      Name: "NAT"

    wait: yes

  register: nat

  tags:

    - vpcsetup

I am trying to get the instance id from the registered value nat. Here is what I get when I debug the nat variable:

ok: [localhost] => {

    "nat": {

        "changed": false, 

        "instance_ids": null, 

        "instances": [], 

        "tagged_instances": [

            {

                "ami_launch_index": "0", 

                "architecture": "x86_64", 

                "block_device_mapping": {

                    "/dev/xvda": {

                        "delete_on_termination": true, 

                        "status": "attached", 

                        "volume_id": "vol-xxxxxx"

                    }

                }, 

                "dns_name": "ec2-xxxxxxx.compute-1.amazonaws.com", 

                "ebs_optimized": false, 

                "groups": {

                    "sg-xxxxxx": "nat-sg"

                }, 

                "hypervisor": "xen", 

                "id": "i-xxxxxxxxxxxxxxxx", 

                "image_id": "ami-xxxxxxxxx", 

                "instance_type": "m4.large", 

                "kernel": null, 

                "key_name": "kp", 

                "launch_time": "2016-02-09T04:42:36.000Z", 

                "placement": "us-east-1a", 

                "private_dns_name": "ip-xxxxx.ec2.internal", 

                "private_ip": "xxxxx", 

                "public_dns_name": "ec2-xxxxx.compute-1.amazonaws.com", 

                "public_ip": "xxxxxx", 

                "ramdisk": null, 

                "region": "us-east-1", 

                "root_device_name": "/dev/xvda", 

                "root_device_type": "ebs", 

                "state": "running", 

                "state_code": 16, 

                "tags": {

                    "Name": "NAT", 

                    "type": "nat"

                }, 

                "tenancy": "default", 

                "virtualization_type": "hvm"

            }

        ]

    }

}

I see that the instance_ids is set to null, but there is a value for id. How do I get the id value? I tried several variations to get the value, but no luck. I keep getting an error saying either:

{"failed": true, "msg": "ERROR! 'list object' has no attribute 'id'"}

or

{"failed": true, "msg": "ERROR! 'dict object' has no attribute 'id'"}

Thanks in advance.
