-# [fit] **Deploying PHP applications** <br>using Ansible, Ansible Vault <br>and Ansistrano
-
-^ I work primarily with PHP, and there will be some PHP-isms in this talk (LAMP
-stack, Composer). Will be using a Drupal 8 application as the example, but the
-tools are tool and language agnostic.

-## **What we'll be looking at**

-- **Ansible** crash course
-- Keeping secrets with **Ansible Vault**
-- Deployments with **Ansistrano**

-# **What is Ansible?**
-
----
-
-## Ansible is an open-source **software provisioning, configuration management, and application-deployment** tool.

-### **What is Ansible?**
-
-- CLI tool
-- Written in Python
-- Configured with YAML
-- Executes ad-hoc remote commands
-- Installs software packages
-- Performs deployment steps
-- Batteries included
-
-^ Written in Python but you don't need to write or know Python to use it Drupal,
-Symfony and a lot of other projects use YAML First-party modules (SSH keys, file
-and directory management, package repositories, stopping/starting/restarting
-services, DO/Linode/AWS integration)
-

-
-### **What is Ansible?**
-
-- Hosts/Inventories
-- Commands
-- Playbooks
-- Tasks
-- Roles
-
-^ Hosts: where your managed nodes/hosts are. Can be static or dynamic. Commands:
-run from a control node onto managed nodes Playbooks and Tasks: YAML
-representation of a series of commands/steps
-
----
-
-![10% right](images/ansible.png)
-
-### **Why Ansible?**
-
-- Familiar syntax
-- Easily readable
-- No server dependencies
-- Easy to add to an existing project
-- Includes relevant modules (e.g. Composer)
-- Idempotency
-
-^ Drupal 8, Symfony, Ansible all use YAML Runs on any server with Python Plugins
-into Drupal via CLI apps like Drush and Drupal Console Changes are only made
-when needed (once)
