Repeat a task based on a csv string from extra_var

[GoFigure]

Hello All,

There is a specific nut I am trying to crack in ansible. We want to dev a job template that add disks to and server instance. The size and number of disk will be provided as an extra_var csv string, eg. 10,100,25,200 would add 4 disks of sizes 10GB, 100GB, 25GB & 200GB. We have the task ready and it works, so adding one disk is not a problem, but how do we then repeat that task for the next disk? Its not a question of nuts and bolts of adding disks, its a question how do we take the csv string (not file) and then loop the task.

Looks like this is possible in Ansible, as per the below articles.

or is this something that requires developing a module?

Thanks

- hosts: localhost

  vars:

    foo: 10,30,20

  tasks:

    - debug:

        var: item

      with_list: "{{ foo.split(',') }}"

 

TASK [debug] *******************************************************************

ok: [localhost] => (item=10) => {

    "attempts": 1, 

    "changed": false, 

    "item": "10"

}

ok: [localhost] => (item=30) => {

    "attempts": 1, 

    "changed": false, 

    "item": "30"

}

ok: [localhost] => (item=20) => {

    "attempts": 1, 

    "changed": false, 

    "item": "20"

}

Thanks Flowerysong, that helps.... been playing a bit, but this does exactly the trick.
