Including and overriding Ansible galaxy roles in my roles

Hi
So this is a refined version of a question I asked before. I have a role that aims to:

  • Do some specific change such as creating users
  • Install nodejs and ruby using rbenv
  • Run a rails app

I’m using two dependencies from Ansible galaxy for that:

How I do that at the moment is to install those roles using a requirements.txt file, and include them in my site.yml:

  • hosts: all
    user: ubuntu
    sudo: true

roles:

  • base-ami
  • nodesource.node
  • zzet.rbenv
  • rails

Now I have two questions.

  1. Is there a way to include these roles from within one of my roles instead of the site.yml file so that I’ll have just one role (base-ami) instead of four showing up in my site.yml. I tried to do something like this:
  • name: Include the nodesource.node role
    include: zzet.rbenv

But then it would expect to see the role in my Ansible playbook. Is there a way to include a Ansible galaxy role from within my role?

  1. I like what zzet.rbenv does but I want to change the version of Ruby it installs. According to the github page, that is controlled like this:

rbenv:
env: user
ruby_version: 2.1.2

How can I include this Ansible galaxy role in my base-ami role and then override these values?
