Ansible Role Development & Testing with Molecule (Podman)

This guide explains how to create an Ansible role and test it locally using Molecule with the Podman driver.


1. Prerequisites

Install Molecule and Podman driver:

pip install molecule molecule-podman

2. Create a New Role

Navigate to your roles directory and create a new role:

cd ansible/roles
ansible-galaxy init myrole
cd myrole

3. Initialize Molecule with Podman

molecule init scenario default -d podman

4. Edit Molecule Configuration

Edit molecule/default/molecule.yml to set your platform and image, for example:

---
dependency:
  name: galaxy
driver:
  name: podman
platforms:
  - name: instance
    image: ubuntu:20.04
    privileged: true
provisioner:
  name: ansible
  options:
    vvv: true
  env:
    ANSIBLE_ROLES_PATH: ../../../
verifier:
  name: ansible


5. Write Your Role Tasks

Edit tasks/main.yml to add your automation logic.


6. Configure Molecule to Use Your Role

Edit molecule/default/converge.yml:

---
- name: Converge
  hosts: all
  gather_facts: false
  tasks:
    - name: Include role
      ansible.builtin.include_role:
        name: myrole

6. Configure preparation steps (required for python and sudo)

---
---
- name: Prepare
  hosts: all
  gather_facts: false
  tasks:
    - name: Update cache # noqa no-changed-when
      ansible.builtin.raw: apt update

    - name: Install required packages # noqa no-changed-when
      ansible.builtin.raw: apt install -y python3 sudo

### Insert here other preparation steps

8. Run Molecule Tests

From the root of your role directory, run:

molecule test

This will:

  • Build the container
  • Apply your role
  • Run verification steps
  • Destroy the container

8. Notes

  • Systemd: Most Podman containers do not support systemd by default. Use when: ansible_service_mgr == "systemd" to skip service tasks in containers.
  • Role Path: Always run Molecule commands from the root of your role directory.
