Simple Ansible Infrastructure Orchestration Example

Ansible playbooks are flexible and powerful. But sometimes, you just need to run a single command on a set of hosts. That's where the simple ansible command comes in handy.

Just like the device in Ender's Game, the ansible command allows you to run commands or call Ansible modules immediately on one or one hundred of servers.

This project configures three Virtual Machines using Vagrant and VirtualBox: app1, app2, and db, to emulate a small-scale real-world infrastructure (two application servers and a database server), so you can practice running ansible commands across them, and work on a flexible Ansible inventory.

Quick Start Guide

1 - Install dependencies (VirtualBox, Vagrant, Ansible)

  1. Download and install VirtualBox.
  2. Download and install Vagrant.
  3. [Mac/Linux only] Install Ansible.

Note for Windows users: This guide assumes you're on a Mac or Linux host. Windows hosts are unsupported at this time.

2 - Build the Virtual Machine

  1. Download this project and put it wherever you want.
  2. Open Terminal, cd to this directory (containing the Vagrantfile and this README file).
  3. Type in vagrant up, and let Vagrant do its magic.

Note: If there are any errors during the course of running vagrant up, and it drops you back to your command prompt, just run vagrant provision to continue building the VM from where you left off. If there are still errors after doing this a few times, post an issue to this project's issue queue on GitHub with the error.

3 - Create an Inventory file, and run ansible commands
