ec2_eip and device_id

[Robert Haskins]

I am trying to assign a single elastic IP to a single AWS instance using this:

  - name: associate an assigned IP with a running instance

    ec2_eip:

      region: "{{ aws_region }}"

      ip: "{{ eip.public_ip }}"

      device_id: "{{ ec2.instance_ids }}"

    register: eip

This is what I am getting back for a response:

fatal: [localhost]: FAILED! => {

    "changed": false,

    "failed": true,

    "invocation": {

        "module_args": {

            "aws_access_key": null,

            "validate_certs": true,

            "wait_timeout": "300"

        },

        "module_name": "ec2_eip"

    },

    "msg": "EC2ResponseError: 400 Bad Request\n<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Response><Errors><Error><Code>InvalidNetworkInterfaceId.Malformed</Code><Message>Invalid id: \"['i-077050831eb30d9da']\" (expecting \"eni-...\")</Message></Error></Errors><RequestID>d13bc6c2-ee3a-48ed-8e64-a84caea7bbfc</RequestID></Response>"

}

The error coming back from AWS seems to indicate device_id is expecting a eni, but the docs clearly say that device_id can be an EC2 instance ID:

http://docs.ansible.com/ansible/ec2_eip_module.html#options

What am I doing wrong? Do I have to somehow token-ize the ec2_instance_ids?

Thanks!
