What do you mean all of your variables are in roles? As in role defaults?
If so, that's fine, use inventory variables to override them.
Your 3 environment scenario is fairly typical. The approach depends on
you.
Here's a couple of rough approaches (hard to tell based on your
description).
1) have a separate inventory for each environment.
The playbook would be the same, but you would have to point to a different
inventory file for each run (using -i).
2) have each environment be a group(dev, stage, prod), and
group/environment specific vars are set as inventory group_vars. Have your
machines belong to the group that corresponds to their environment, and
they will include the proper variables. Use a intersection host-pattern to
target the group in your playbook:
Assuming env is defined as an extra var, and you ran:
ansible-playbook -e "env=dev" playbook.yml -i inventory/
and playbook.yml started with something like this:
- hosts: web:&{{ env }}
roles:
- foo
- bar
it would target your web servers in your dev environment.
Some folks will even have completely separate cloud credentials for
dev/staging/prod. It all comes down with what level of complexity your
comfortable with.
