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.docker

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
    - role: robertdebock.core_dependencies
    - role: robertdebock.buildtools
    - role: robertdebock.epel
    - role: robertdebock.python_pip

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

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

  tasks:
    - name: Create a container
      docker_container:
        name: openssh
        image: robertdebock/docker-centos-openssh
        ports:
          - "2222:22"
      when:
        - ansible_connection != "docker"

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

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:

---
- robertdebock.bootstrap
- robertdebock.buildtools
- robertdebock.core_dependencies
- robertdebock.epel
- robertdebock.python_pip

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
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
Ubuntu	Unable to find any of pip2, pip to use.
amazonlinux	Required dependency (python_pip) does not work on amazonlinux.

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
