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: yes
  gather_facts: yes

  roles:
    - role: robertdebock.grub
      grub_options:
        - option: cgroup_enable
          value: memory
        - option: systemd.unified_cgroup_hierarchy
          value: 0

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

---
- name: Prepare
  hosts: all
  become: yes
  gather_facts: no

  roles:
    - role: robertdebock.bootstrap

  tasks:
    - name: Make /etc/default
      ansible.builtin.file:
        path: /etc/default
        state: directory
        mode: "0755"

    - name: Place bogus /etc/default/grub
      ansible.builtin.copy:
        content: 'GRUB_CMDLINE_LINUX="a=1"'
        dest: /etc/default/grub
        mode: "0664"

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 grub

grub_timeout: 5

grub_recordfail_timeout: "{{ grub_timeout }}"

# Add options here, for example:
# grub_options:
#   - option: cgroup_enable
#     value: memory
