GitHub	Downloads	Version

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: show virtualization type fot Ansible role testing
      ansible.builtin.debug:
        msg: "{{ ansible_virtualization_type }}"

  roles:
    - role: "mullholland.swap"

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

---
- name: Prepare
  hosts: all
  become: true
  gather_facts: true

  tasks:
    - name: Fedora | Install util-linux for fallocate
      ansible.builtin.package:
        name: "util-linux"
        state: present
      when: ansible_distribution == "Fedora"

Role Variables

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

---
swap_file_name: "swap"  # Filename of the swapfile
swap_file_path: "/"  # Path of the swap (Path needs an "/" at the end)
swap_file_size: "1024"  # Size in MB
swap_file_state: "present"  # Either "present" or "absent"

# create the swapfile with:
# - "fallocate"
# - "dd"
swap_create: "fallocate"

# Configure swappiness
# if variable is empty nothing will be changed on the system
swap_swappiness: ""

# swap_vfs_cache_pressure
