i’m just getting started with Ansible, and would appreciate some help on how best to compose functionality with tasks, roles and modules.

i’m thinking of a basic structure that i imagine is somewhat common, where

- hosts have projects

- projects have github repos

- github repos have git module tasks that actually clone the repo  
some pseudo code:

some-project  
github\_repo:  
owner: nrser  
name: some-project

github\_repo

git:  
repo: [git@github.com](mailto:git@github.com):{{ owner }}/{{ name }}  
dest: "{{ gh\_root }}/{{ owner }}/{{ name }}

how should i accomplish this in Ansible? should `some-project` and `github_repo` be tasks, roles…?

Have a look at 'parameterized roles' at :
