It worked well, but left some room for improvement: + +- *Base OS image* - It provides only `centos:centos7` and `ubuntu:14.04`. Insufficent for me. + +- *Unnecessary dependencies* - It installed, at the very beginning of its Dockerfile, the `software-properties-common` package, which in turns installed some Python packages. I prefered to incorporate these stuff only when absolutely needed. + +Therefore, I built these Docker images on my own. + + +## Usage + +Used mostly as a *base image* for configuring, with Ansible, other software stack on some specified Linux distribution. + +Take Debian/Ubuntu for example. To test an Ansible `playbook.yml` against a variety of Linux distributions, we may use [Vagrant](https://www.vagrantup.com/) as follows: + +```ruby +# Vagrantfile + +Vagrant.configure(2) do |config| + + # ==> Choose a Vagrant box to emulate Linux distribution... + config.vm.box = "ubuntu/trusty64" + #config.vm.box = "hashicorp/precise64" + #config.vm.box = "chef/debian-7.8" + + # ==> Executing Ansible... + config.vm.provision "ansible" do |ansible| + ansible.playbook = "playbook.yml" + end + +end +``` + +Virtual machines can emulate a variety of Linux distributions, at the cost of runtime overhead. + +Docker to be a rescue. Now, with these **williamyeh/ansible** series, we may test an Ansible `playbook.yml` against a variety of Linux distributions as follows: + + +```dockerfile +# Dockerfile + +# ==> Choose a base image to emulate Linux distribution... +FROM williamyeh/ansible:ubuntu14.04 +#FROM williamyeh/ansible:ubuntu12.04 +#FROM williamyeh/ansible:debian7 + +# ==> Copying Ansible playbook... +WORKDIR /tmp +COPY . /tmp + +# ==> Creating inventory file... +RUN echo localhost > inventory + +# ==> Executing Ansible... +RUN ansible-playbook -i inventory playbook.yml \ + --connection=local --sudo +``` + +With Docker, we can test any Ansible playbook against any version of any Linux distribution without the help of Vagrant.
