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: buluma.stratis
    # It's not easy to test block-devices in CI. That's why the next block
    # of variables is commented, but left here as an example.
    #    stratis_pools:
    #      - name: my_pool
    #        devices:
    #          - /dev/vdb
    #          - /dev/vdc
    #    stratis_filesystems:
    #      - name: my_filesystem
    #        pool: my_pool
    #    stratis_mounts:
    #      - mountpoint: /mnt/my_mountpoint
    #        device: /stratis/my_pool/my_filesystem

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

  vars:
    devices:
      - name: vdc
        major: 252
        minor: 2
      - name: vdd
        major: 252
        minor: 3

  roles:
    - role: buluma.bootstrap

  tasks:
    - name: create storage file
      command: dd if=/dev/zero of=/{{ item.name }} bs=1M count=1K
      args:
        creates: "/{{ item.name }}"
      loop: "{{ devices }}"
      notify:
        - create loopback device
        - loopback device to storage file
      loop_control:
        label: "/{{ item.name }}"

  handlers:
    - name: create loopback device
      command: mknod /dev/{{ item.name }} b {{ item.major }} {{ item.minor }}
      loop: "{{ devices }}"
      loop_control:
        label: "/dev/{{ item.name }}"
      changed_when: false

    - name: loopback device to storage file
      command: losetup /dev/{{ item.name }} /{{ item.name }}
      loop: "{{ devices }}"
      failed_when: false
      loop_control:
        label: "/dev/{{ item.name }} to /{{ item.name }}"
      changed_when: false
