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

  roles:
    - role: robertdebock.lvm
      # It's difficult to test this in CI.
      # lvm_volume_groups:
      #   - name: first
      #     pvs:
      #       - /dev/loop0

      # There is no device mapper in containers.
      # lvm_logical_volumes:
      #   - name: first
      #     vg: first
      #     size: 100%FREE
      #     opts: --type cache-pool

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: robertdebock.bootstrap

  # tasks:
  #   - name: create disk.img
  #     command: dd if=/dev/zero of=/disk.img bs=1M count=100
  #     args:
  #       creates: /disk.img

  #   - name: create /dev/loop0
  #     command: mknod /dev/loop0 b 7 8
  #     args:
  #       creates: /dev/loop0
  #     notify:
  #       - link disk.img to /dev/loop0

  # handlers:
  #   - name: link disk.img to /dev/loop0
  #     command: losetup /dev/loop0 /disk.img
