## Example Playbook
|
|
|
|
This example is taken from `molecule/resources/converge.yml` and is tested on each push, pull request and release.
|
|
```yaml
|
|
---
|
|
- name: Converge
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
roles:
|
|
- role: robertdebock.grub
|
|
grub_options:
|
|
- option: cgroup_enable
|
|
value: memory
|
|
```
|
|
|
|
The machine may need to be prepared using `molecule/resources/prepare.yml`:
|
|
```yaml
|
|
---
|
|
- 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` run after the role has been applied.
|
|
```yaml
|
|
---
|
|
- name: Verify
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
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
|
|
```
|
|
|
|

|
## Role Variables
|
|
|
|
These variables are set in `defaults/main.yml`:
|
|
```yaml
|
|
---
|
|
# defaults file for grub
|
|
|
|
grub_timeout: 5
|
|
|
|
# Add options here, for example:
|
|
# grub_options:
|
|
# - option: cgroup_enable
|
|
# value: memory
|
|
```
|
|
|
|
## Requirements
|
|
|
|
- Access to a repository containing packages, likely on the internet.
|
|
- A recent version of Ansible. (Tests run on the current, previous and next release of Ansible.)
|
|
|
|
The following roles can be installed to ensure all requirements are met, using `ansible-galaxy install -r requirements.yml`:
|
|
|
|
```yaml
|
|
---
|
|
- robertdebock.bootstrap
|
|
|
|
```
|
|
|
|
## Context

|
## Compatibility
|
|
|
|
This role has been tested on these [container images](https://hub.docker.com/):
|
|
|
|
|container|tags|
|
|
|---------|----|
|
|
|debian|all|
|
|
|el|7, 8|
|
|
|fedora|all|
|
|
|opensuse|all|
|
|
|ubuntu|bionic, xenial, focal|
|
|
|
|
The minimum version of Ansible required is 2.8 but tests have been done to:
|
|
|
|
- The previous version, on version lower.
|
|
- The current version.
|
|
- The development version.
|
|
|
|
|
|
|
|
## Testing
|
|
|
|
[Unit tests](https://travis-ci.com/robertdebock/ansible-role-grub) are done on every commit, pull request, release and periodically.
|
|
|
|
If you find issues, please register them in [GitHub](https://github.com/robertdebock/ansible-role-grub/issues)
|
|
|
|
Testing is done using [Tox](https://tox.readthedocs.io/en/latest/) and [Molecule](https://github.com/ansible/molecule):
|
|
|
|
[Tox](https://tox.readthedocs.io/en/latest/) tests multiple ansible versions.
|
|
[Molecule](https://github.com/ansible/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
|
|
```
