 # Vagrant and Ansible

 ---

 # Agenda

 1. What is Vagrant?
 2. How to use Vagrant?
 3. What is Ansible?
 4. Ansible
 5. Demo

 ---

 #Goals

 - Try to spike some interest about things that aren't just shell ;)

 #Non-goals

 - A complete and comprehensive guide to Ansible and Vagrant.

 ---

 # What is Vagrant?

 - Vagrant is an abstraction of virtual machines
 --

 - Vagrant is a description of One or more Virtual Machines.
 --

 - Vagrant is a tool to make Development easier.

 ---

 # How to use Vagrant?

 download a package from http://www.vagrantup.com/downloads

 ## On OSX:

 ```bash
 brew cask install vagrant
 ```

 ## On Debian-derived GNU/Linux

 ```bash
 curl http://bit.ly/1Vd6ryG -o /tmp/vagrant.deb

 sudo dpkg -i /tmp/vagrant.deb
 ```


 ---

 # How to use Vagrant?

 Examples assumes you have installed [VirtualBox](http://virtualbox.org)

 Simplest possible case

 This command creates a `Vagrantfile`

 ```bash
 vagrant init ubuntu/trusty64 http://bit.ly/1KyU5J9
 ```

 This command starts the instance and provisions according to the [Provisioner](https://docs.vagrantup.com/v2/provisioning/ansible.html)
 ```bash
 vagrant up
 ```

 This command destroys the instance and the virtualbox instance with all data.
 ```bash
 vagrant destroy
 ```

 # What is [Ansible](http://www.ansible.com/)

 ##Wikipedia
 <blockquote>
 Ansible is a free software platform for configuring and managing computers. It combines multi-node software deployment, ad hoc task execution, and configuration management. It manages nodes over SSH or PowerShell and requires Python (2.4 or later) to be installed on them. Modules work over JSON and standard output and can be written in any programming language. The system uses YAML to express reusable descriptions of systems.
 </blockquote>

 In short; Its a configuration management platform that uses SSH.

 ---

 # Ansible

 A root ansible file is known as a <em>Playbook</em>


 ```yaml
 ---
 - hosts: webservers
  tasks:
    - name: Gather information
      copy: >
        dest=/etc/motd.tail
        content='Here be your message'
        mode=0644
        owner=root
        group=root
      sudo: yes
 ```

 ---

 # Ansible role

 An ansible role is a `directory` which has a special directory structure.

 The goal of an Ansible role is to make a certain set of tasks reusable.

 ---

 #Examples

 ##Installing


 - nginx
 --
 count: false
 - tomcat
 --
 count: false
 - mysql
 --
 count: false
 - content-engine
 --
 count: false

 ## Configuration of

 - content-engine
 --
 count: false
 - tomcat
 --
 count: false
 - mysql user and database


 ---
 # Ansible role

 ```
  <rolename>
    defaults?/main.yml
    tasks/main.yml
    meta?/main.yml
    handlers?/main.yml
    vars?/main.yml
    files?/...
    templates?/...
 ```

 The <em>?</em> denotes an optional directory

 The <em>...</em> denotes any type of file

 Next to the playbook that needs the role, it usually lives within a `roles` directory.

 # Ansible galaxy

 A repository for re-usable roles found [here](https://galaxy.ansible.com/)

 <aside>The quality of the different roles varies a lot.</aside>

 # Q/A

 ---

 # This might also be interesting

 * ## packer.io seems like somthing to watch, especially when building tooling.
 --

 * ## Immutable infrastructure

 --
 * ## Combination with [asgard](https://github.com/Netflix/asgard). Used successfully at SPT ( Schibsted Product &amp; Technolgies)
