Ansible Playbooks vs Roles

Question

According to the Ansible docs, a Playbook is:

...the basis for a really simple configuration management and multi-machine deployment system, unlike any that

Answer 1

Also keep in mind a playbook can call more than one role if a meta file is used that is intended to affect the different roles.

Example Playbook: dual_role-playbook.yml

- name: Some Action for two roles
  hosts: localhost

  vars_files:
    - roles/dual_role/meta/main.yml

  roles:
    - dual_role/container-1
    - dual_role/container-2

The role folder and files scheme will look like this:

dual_role-playbook.yml
  -- roles
     -- dual_role
        -- meta/main.yml
        -- container-1
           -- tasks/main.yml
           -- templates/template.j2
        -- container-2
           -- tasks/main.yml
           -- templates/template.j2
