How to connect the Ansible role into a Playbook script?

To include a role in an Ansible Playbook, the keyword roles is used. In the playbook section where tasks are described for hosts, a list of roles to be applied is added.

Example of including the common role:

- hosts: all
  roles:
    - common

If you need to pass parameters to a role, you can use a dictionary:

- hosts: all
  roles:
    - role: common
      vars:
        some_variable: value

Thus, roles allow structuring and reusing configurations in Ansible.
