Example Playbook

This example is taken from molecule/resources/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 may need to be prepared using molecule/resources/prepare.yml:

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

  roles:
    - role: robertdebock.bootstrap

  tasks:
    - name: make /etc/default
      file:
        path: /etc/default
        state: directory
    - name: place bogus /etc/default/grub
      copy:
        content: 'GRUB_CMDLINE_LINUX="a=1"'
        dest: /etc/default/grub

For verification molecule/resources/verify.yml runs after the role has been applied.

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

  tasks:
    - name: check that bogus options are in
      command: grep 'a=1' /etc/default/grub

    - name: check that selected option is in
      command: grep 'cgroup_enable=memory' /etc/default/grub

Also see a full explanation and example on how to use these roles.

The following roles can be installed to ensure all requirements are met, using ansible-galaxy install -r requirements.yml:

---
- robertdebock.bootstrap

If you find issues, please register them in GitHub

Testing is done using Tox and Molecule:

Tox tests multiple ansible versions. Molecule tests multiple distributions.

To test using the defaults (any installed ansible version, namespace: robertdebock, image: fedora, tag: latest):

molecule test

# Or select a specific image:
image=ubuntu molecule test
# Or select a specific image and a specific tag:
image="debian" tag="stable" tox

Or you can test multiple versions of Ansible, and select images: Tox allows multiple versions of Ansible to be tested. To run the default (namespace: robertdebock, image: fedora, tag: latest) tests:

tox

# To run CentOS (namespace: `robertdebock`, tag: `latest`)
image="centos" tox
# Or customize more:
image="debian" tag="stable" tox
