unable to specify volumes for new instance

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!

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.

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
