Looking up vars from files

[Neil Saunders]

Hi All - 

I'm trying iterate over a list of dicts stored in an external file.

My variables file (vpc.yml) is as follows:

---
eu-west-1:
    stage:
        - { name: eu-west-1a, subnet: subnet-832023ea }
        - { name: eu-west-1b, subnet: subnet-10272479 }
        - { name: eu-west-1c, subnet: subnet-8e2724e7 }
    live:
        - { name: eu-west-1a, subnet: subnet-cd340ea4 }
        - { name: eu-west-1b, subnet: subnet-18272471 }
        - { name: eu-west-1c, subnet: subnet-37af955e }
<snip>

And my task definition is:

---
- hosts: 127.0.0.1
  connection: local
  vars_files:
    - vpc.yml


  tasks:
    - name: Create ASG for each zone
      ec2_asg:
        name: "{{ component_name }}-{{ environment }}-{{ item.name }}"
        availability_zones: [ "{{ item.name }}" ]
        launch_config_name: 'lc-1'
        min_size: 1
        max_size: 10
        desired_capacity: 1
        vpc_zone_identifier: [ "{{ item.subnet }}" ]
        tags:
          - Component: "{{ component_name }}"
          - ComponentVersion: "{{ component_name }}"
          - EnvLevel: "{{ environment }}"
          - ClusterName: "{{ cluster_name }}"
          - Country: "{{ country }}"
            propagate_at_launch: yes
        with_items: {{ region[environment] }}

Which I then invoke with:

ansible-playbook create-clustered-persistance-infra.yml --check -i inventory.ini --extra-vars="component_name=elasticsearch environment=stage clustername=eventsearch instance_type=m1.medium country=us region=us-east-1 component_version=9 component_ami=ami-293872"

But receive the error: 

TASK: [Create ASG for each zone] **********************************************

fatal: [127.0.0.1] => One or more undefined variables: 'item' is undefined

FATAL: all hosts have already failed -- aborting

I've tried what feels like every combination of brackets and quotes, but I'm clearly missing something.

Any assistance gratefully received.

Ta,

Neil

Ok - It appears to be an issue with the indentation level of with_items - I've dropped if back a level but an now receiving:

TASK: [Create ASG for each zone] **********************************************

fatal: [127.0.0.1] => with_items expects a list or a set

FATAL: all hosts have already failed -- aborting

how does region tie to eu-west-1?

Hi Brian - eu-west-1 is the region.

[Brian Coca]

still, how does that become?

with_items: {{ region[environment] }}

also note that - is not a good character for variable names
