Ansible is a radically simple and lightweight provisioning framework which makes your servers and applications easier to provision and deploy. By orchestrating your application deployments you gain benefits such as documentation as code, testability, continuous integration, version control, refactoring, automation and autonomy of your deployment routines, server- and application configuration. Ansible uses a language that approaches plain English, uses SSH and has no agents to install on remote systems. It is the simplest way to automate and orchestrate application deployment, configuration management and continuous delivery.
In this talk you will be given an introduction to Ansible and learn how to provision Linux servers with a web-proxy, a database and some other packages. Furthermore we will automate zero downtime deployment of a Java application to a load balanced environment.
We will cover how to provision servers with:
* an application user
* a PostgreSQL database
* nginx with a load balanced reverse proxy
* an init script installed as a service
* zero downtime deployment of an application that uses the provisioned infrastructure
