Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

---
- name: Converge
  hosts: all
  become: yes
  gather_facts: yes

  roles:
    - role: robertdebock.cve_2021_44228

The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  become: yes
  gather_facts: no

  roles:
    - role: robertdebock.bootstrap

  # The role is prepared to install extra software and also remove when
  # the role is done. This is not idempotent, so in this playbook, the
  # required software is already installed.
  vars_files:
    - ../../vars/main.yml

  post_tasks:
    - name: Install required software
      ansible.builtin.package:
        name: ["{{ cve_2021_44228_ps_package }}", unzip]
