Okay, so in the interest of moving to exact_count I switched from:
- name: Set up a new host instance on EC2
> ec2: >
> region="{{ ec2vars.region }}"
> zone="{{ ec2vars.zone }}"
> id="{{ serverPod + '_' + type }}"
> ec2_access_key="{{ ec2vars.ec2_access_key }}"
> ec2_secret_key="{{ ec2vars.ec2_secret_key }}"
> key_name="{{ ec2vars.key_name }}"
> instance_type="{{ ec2vars.instance_type }}"
> image="{{ ec2vars.image }}"
> group="{{ ec2vars.group }}"
> wait="{{ wait }}"
> wait_timeout=600
> user_data="{{ type }}"
> instance_tags='{"ec2serverPod":"{{ serverPod }}", "ec2type":"{{ type
> }}", "ec2serverPod_and_ec2type":"{{ serverPod }}_{{ type }}",
> "provisioned":"False", "Name":"{{ virtualhostFullName }}_{{ type }}"}'
> count="{{ count }}"
> vpc_subnet_id="{{ ec2vars.vpc_subnet_id }}"
> register: ec2
>
to:
- name: Set up a new host instance on EC2
> ec2: >
> region="{{ ec2vars.region }}"
> zone="{{ ec2vars.zone }}"
> ec2_access_key="{{ ec2vars.ec2_access_key }}"
> ec2_secret_key="{{ ec2vars.ec2_secret_key }}"
> key_name="{{ ec2vars.key_name }}"
> instance_type="{{ ec2vars.instance_type }}"
> image="{{ ec2vars.image }}"
> group="{{ ec2vars.group }}"
> wait="{{ wait }}"
> wait_timeout=600
> user_data="{{ type }}"
> instance_tags='{"ec2serverPod":"{{ serverPod }}", "ec2type":"{{ type

but I seem to have lost idempotence because I get new instances every time
it runs. I've since reformatted it to drop the quoted block and make it
look more like the docs but there was no improvement:
- name: Set up a new host instance on EC2
> local_action:
> module: ec2
> region: "{{ ec2vars.region }}"
> zone: "{{ ec2vars.zone }}"
> ec2_access_key: "{{ ec2vars.ec2_access_key }}"
> ec2_secret_key: "{{ ec2vars.ec2_secret_key }}"
> key_name: "{{ ec2vars.key_name }}"
> instance_type: "{{ ec2vars.instance_type }}"
> image: "{{ ec2vars.image }}"
> group: "{{ ec2vars.group }}"
> wait: "{{ wait }}"
> wait_timeout: 600
> user_data: "{{ type }}"
> instance_tags: '{"ec2serverPod":"{{ serverPod }}", "ec2type":"{{ type
> }}", "ec2serverPod_and_ec2type":"{{ serverPod }}_{{ type }}",
> "provisioned":"False", "Name":"{{ virtualhostFullName }}_{{ type }}"}'
> exact_count: "{{ count }}"
> count_tag: ec2serverPod_and_ec2type:"{{ serverPod }}_{{ type }}"
> vpc_subnet_id: "{{ ec2vars.vpc_subnet_id }}"

Anyone see anything obvious with that last example? Do I have to list all
of the instance's tags in count_tag?
Thank you,
Mark
