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.common

The machine may need to be prepared using molecule/resources/prepare.yml:

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

  roles:
    - role: robertdebock.bootstrap

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 if connection still works
      ping:

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

# common_nameservers:
#   - 1.1.1.1

Context

This role is a part of many compatible roles. Have a look at the documentation of these roles for further information.

Here is an overview of related roles:

Compatibility

This role has been tested on these container images:

container	tags
alpine	all
amazon	2018.03
el	7, 8
debian	buster, bullseye
fedora	31, 32
opensuse	all
ubuntu	focal, bionic, xenial

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.

Exceptions

Some variarations of the build matrix do not work. These are the variations and reasons why the build won't work:

variation	reason
amazonlinux	set hostname: [Errno 2] No such file or directory: '/etc/sysconfig/network'

Testing

Unit tests are done on every commit, pull request, release and periodically.

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
