+This repository contains Dockerized [Ansible](https://github.com/ansible/ansible), published to the public [Docker Hub](https://hub.docker.com/) via **automated build** mechanism.
These are Docker images for [Ansible](https://github.com/ansible/ansible) software, installed in a selected Linux distributions.
-- OS: Debian (jessie, wheezy), Ubuntu (trusty, precise), CentOS (7, 6)
+### Base OS
-- Ansible: usually the latest version.
+Debian (stretch, jessie), Ubuntu (xenial, trusty), CentOS (7), Alpine (3).
+
+Supports for Wheezy, Precise, and CentOS6 have been ended since Sep 2017.
+
+### Ansible
+
+Four versions are provided:
+
+ 1. provides the most recent *stable* version of Ansible; suitable for most people.
+ 2. same as stable version, but is designed for building (near-)*minimal* images out of playbooks; i.e., the Ansible body will be removed when mission completed. Refer to “[Build Docker images with Ansible: A half-blood approach](https://github.com/William-Yeh/build-docker-with-ansible)” for working examples and slides.
+ 3. provides the old 1.9 version of Ansible (but will be retired someday).
+ 4. provides the *experimental* version of Ansible; i.e., the master branch of official [Ansible's git repo](https://github.com/ansible/ansible).
+
+Each version is further divided into two variants:
+
+- *Normal* variant: intended to be used as Ansible *control machines*, or in cases that is inadequate in the onbuild variants.
+- *Onbuild* variant: intended to be used to build Docker images.

## For the impatient
# ==> Specify inventory filename; default = "/etc/ansible/hosts"
#ENV INVENTORY inventory.ini
-# ==> Executing Ansible...
+# ==> Executing Ansible (with a simple wrapper)...
RUN ansible-playbook-wrapper
```
Done!
-For more advanced usage, the role in Ansible Galaxy [`williamyeh/nginx`](https://galaxy.ansible.com/list#/roles/2245) also demonstrates how to do a simple integration test for a variety of Linux distributions on [CircleCI](https://circleci.com/)'s and [Travis CI](https://travis-ci.org/)’s Ubuntu 12.04 worker instances.

## Why yet another Ansible image for Docker?
-There has been quite a few Ansible images for Docker (e.g., [search](https://registry.hub.docker.com/search?q=ansible) in the Docker Hub), so why reinvent the wheel?

In the beginning I used the [`ansible/ansible-docker-base`](https://github.com/ansible/ansible-docker-base) created by Ansible Inc. It worked well, but left some room for improvement:
ansible/centos7-ansible stable 367.5 MB
ansible/ubuntu14.04-ansible stable 286.6 MB
+williamyeh/ansible alpine3-onbuild 66.4 MB
williamyeh/ansible centos6-onbuild 264.2 MB
williamyeh/ansible centos7-onbuild 275.3 MB
williamyeh/ansible debian7-onbuild 134.4 MB
## Usage
-Used mostly as a *base image* for configuring, with Ansible, other software stack on some specified Linux distribution.
+Used mostly as a *base image* for configuring other software stack on some specified Linux distribution(s).
Take Debian/Ubuntu/CentOS for example. To test an Ansible `playbook.yml` against a variety of Linux distributions, we may use [Vagrant](https://www.vagrantup.com/) as follows:
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"
- #config.vm.box = "chef/centos-7.0"
- #config.vm.box = "chef/centos-6.6"
+ config.vm.box = "ubuntu/xenial64"
+ #config.vm.box = "ubuntu/trusty64"
+ #config.vm.box = "debian/stretch64"
+ #config.vm.box = "debian/jessie64"
+ #config.vm.box = "bento/centos-7.2"
+ #config.vm.box = "maier/alpine-3.3.1-x86_64"
# ==> Executing Ansible...
# Dockerfile
# ==> Choose a base image to emulate Linux distribution...
-FROM williamyeh/ansible:ubuntu14.04
-#FROM williamyeh/ansible:ubuntu12.04
+FROM williamyeh/ansible:ubuntu16.04
+#FROM williamyeh/ansible:ubuntu14.04
+#FROM williamyeh/ansible:debian9
#FROM williamyeh/ansible:debian8
-#FROM williamyeh/ansible:debian7
#FROM williamyeh/ansible:centos7
-#FROM williamyeh/ansible:centos6
+#FROM williamyeh/ansible:alpine3
# ==> Copying Ansible playbook...
--connection=local --sudo
```
-Or, more simple with `onbuild` series:
+You may also work with `onbuild` variants, which take care of many routine steps for you:
```dockerfile
# Dockerfile
# ==> Choose a base image to emulate Linux distribution...
-FROM williamyeh/ansible:ubuntu14.04-onbuild
-#FROM williamyeh/ansible:ubuntu12.04-onbuild
+FROM williamyeh/ansible:ubuntu16.04-onbuild

+#FROM williamyeh/ansible:debian9-onbuild
#FROM williamyeh/ansible:debian8-onbuild
-#FROM williamyeh/ansible:debian7-onbuild
#FROM williamyeh/ansible:centos7-onbuild
-#FROM williamyeh/ansible:centos6-onbuild
+#FROM williamyeh/ansible:alpine3-onbuild
# ==> Specify requirements filename; default = "requirements.yml"
# ==> Specify inventory filename; default = "/etc/ansible/hosts"
#ENV INVENTORY inventory.ini
