## [Example Playbook](#example-playbook)

This example is taken from [`molecule/default/converge.yml`](https://github.com/buluma/ansible-role-molecule/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.

```yaml
---
- name: Converge
hosts: all
become: true
gather_facts: true

pre_tasks:
- name: Update apt cache.
apt: update_cache=yes cache_valid_time=600
when: ansible_os_family == 'Debian'
changed_when: false

- name: Check if python3.11 EXTERNALLY-MANAGED file exists
ansible.builtin.stat:
path: /usr/lib/python3.11/EXTERNALLY-MANAGED
register: externally_managed_file_py311

- name: Rename python3.11 EXTERNALLY-MANAGED file if it exists
ansible.builtin.command:
cmd: mv /usr/lib/python3.11/EXTERNALLY-MANAGED /usr/lib/python3.11/EXTERNALLY-MANAGED.old
when: externally_managed_file_py311.stat.exists
args:
creates: /usr/lib/python3.11/EXTERNALLY-MANAGED.old

- name: Check if python3.12 EXTERNALLY-MANAGED file exists
ansible.builtin.stat:
path: /usr/lib/python3.12/EXTERNALLY-MANAGED
register: externally_managed_file_py312

- name: Rename python3.12 EXTERNALLY-MANAGED file if it exists
ansible.builtin.command:
cmd: mv /usr/lib/python3.12/EXTERNALLY-MANAGED /usr/lib/python3.12/EXTERNALLY-MANAGED.old
when: externally_managed_file_py312.stat.exists
args:
creates: /usr/lib/python3.12/EXTERNALLY-MANAGED.old

roles:
- role: buluma.molecule
```

The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/buluma/ansible-role-molecule/blob/master/molecule/default/prepare.yml):

```yaml
---
- name: Prepare
hosts: all
become: true
gather_facts: false

roles:
- role: buluma.bootstrap
- role: buluma.buildtools
- role: buluma.epel
- role: buluma.python_pip
```

Also see a [full explanation and example](https://buluma.github.io/how-to-use-these-roles.html) on how to use these roles.

## [Role Variables](#role-variables)

The default values for the variables are set in [`defaults/main.yml`](https://github.com/buluma/ansible-role-molecule/blob/master/defaults/main.yml):

```yaml
---
# defaults file for molecule

# If you need to give extra options to pip, use `molecule_extra_args`. For
# example:
# molecule_extra_args: "--user"
molecule_extra_args: ""

# A list of plugins to install. (Can be empty.)
molecule_plugins:
- molecule-plugins[docker]
```
