Overview

To get a perfect pie every Chef should take a good testo (pastry in russian). Also this repository is a good start to test(o) a new Infrastructure as Code approach.

We use chef with berkshelf, vagrant and packer to develop infrastructure. The purpose of this repository is to show how to use this tools all together on an example project.

• Searching of indexed data on the Chef server
