unable to specify volumes for new instance

[i iordanov]

Hi guys,

I'm stuck with an issue and hoping somebody can spot my mistake. I have a task like the following where I'm trying to specify a volume for the ec2 instance.

  tasks:
    - name: Start instance
      ec2: image=ami-xxxx
           count=1
           aws_access_key=xxx
           aws_secret_key=yyy
.
.
           volumes='{ "device_name":/dev/sdb, "volume_size":"10" }'
           wait=true

No matter what syntax I try, ansible refuses to accept my specification. I can't specify a single, let alone multiple volumes. Can anybody tell me what the syntax should look like?

Many thanks!
iordan

Hi,

I had some trouble putting everything together with the ec2 module …

with the help of the list I finally got it  working.

As Michael pointed out, with the ec2 module, it is easier to use complex arguments style.

This is a working example:

- hosts: 127.0.0.1

  connection: local

  gather_facts: True

vars:

...

  tasks:

      - name: create a vm

        local_action:

            module: ec2

            image: "{{ image }}"

            count: 1

            instance_type: "{{ instance_type }}"

            group: "{{ group }}"

            key_name: "{{ keypair }}"

            vpc_subnet_id: "{{ subnet }}"

            private_ip: "{{ ip }}"

            user_data: "{{ hostname }}.{{ dnsdomain }}"

            instance_tags: '{"Name":"{{ hostname }}"}'

            volumes:

                - device_name: /dev/sda1

                  volume_size: 10

                - device_name: /dev/sdb

                  ephemeral: ephemeral0

                - device_name: /dev/sdc

                  volume_size: 25

            wait: true

            wait_timeout: 500

            state: present

        register: ec2

Hope this help.

Fred

Hi Fred,

Thank you very much, your suggestion to use complex arguments style was spot on. However, for some reason I couldn't get the parser to accept local_action and my rule took on yet a different form. Here it is, in case it helps somebody!

    - name: Make {{ hostname }}
      ec2:
            image: "{{ ami }}"
            id: "{{ hostname }}"
            instance_tags: '{"Name":"{{ hostname }}", "type":"{{ group }}"}'
            instance_type: "{{ type }}"
            count: "{{ count }}"
            aws_access_key: "{{ ec2_access_key }}"
            aws_secret_key: "{{ ec2_secret_key }}"
            region: "{{ region }}"
            keypair: "{{ keypair }}"
            group_id: "{{ group_id }}"
            vpc_subnet_id: "{{ vpc_subnet_id }}"
            volumes:
                - device_name: "{{ root_dev_name }}"
                  volume_size: "{{ root_dev_size }}"
            state: present
            wait: true
      register: machine_info
      delegate_to: 127.0.0.1
