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: 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:

---
- 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 on how to use these roles.

Role Variables

The default values for the variables are set in defaults/main.yml:

---
# 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]
