with_items x count

[sma...@gmail.com]

Hey just wondering if there is a more elegant way of doing this:

---
droplets:
  - name: consul
    count: [1,2,3,4,5]
    region: nyc2
    region_id: 4
  - name: influxdb
    count: [1,2,3]
    region: nyc2
    region_id: 4
  - name: elasticsearch
    count: [1,2,3,4]
    region: nyc2
    region_id: 4

  vars_files:
    - vars/testing.yml
  tasks:
    - name: Print phone records
      debug: msg="{{ item.0.name }}.{{ item.1 }} in {{ item.0.region }}({{ item.0.region_id }})"
      with_subelements:
        - droplets
        - count

this could get out of control if the counts got into the 100's

would be nice if I could do this:

  - name: consul
    count: 5
    region: nyc2
    region_id: 4

and it looped on the count 5 times.

hoping you have a more elegant solution for me :)

You can simplify that by just using with_items:

  vars:

    droplets:

      - name: consul

        count: 5

        region: nyc2

        region_id: 4

      - name: influxdb

        count: 3

        region: nyc2

        region_id: 4

      - name: elasticsearch

        count: 4

        region: nyc2

        region_id: 4

  tasks:

    - name: Print phone records

      debug: msg="{{ item.name }} in {{ item.region }}({{ item.region_id }})"

      with_items: droplets

Results in output like this:

ok: [127.0.0.1] => (item={'count': 5, 'region': 'nyc2', 'name': 'consul', 'region_id': 4}) => {

    "item": {

        "count": 5, 

        "name": "consul", 

        "region": "nyc2", 

        "region_id": 4

    }, 

    "msg": "consul in nyc2(4)"

}

That only prints each droplet once, not count times. The original would
have given consul.1, consul.2, consul.3, etc.

with_sequence: count=5  I'm not sure how that would work with with_items, but it's worth a try.. (with_nested used with sequences?)

With_sequence could be used to loop over each step X times... But can't be combined with with_items as far as I can tell.

It would be better and much more ansible-playbook-happy to enhance the digital ocean module to support exact_count like ec2 and Rackspace have, rather than having the playbook get a little gross like this.

Both implement them a little differently, and I'm not entirely sure what it might take, but probably not too difficult.
