Evolve

An Evolving Web Server Example

This is a project I've been playing with to get some practice in on tools I haven't touched in a year. I was thinking about the couch to 5k program the other day and thought it might be neat to structure this similarly.

The project uses a variety of open source tools to create and test a web server in different infrastructures.

• Evolve
  • Requirements
  • Assumptions
  • Part 1 Generate a Cookbook
  • Part 2 Write Failing Unit Tests
    • Run the Test
  • Part 3 Write Code to Pass Unit Tests
  • Part 4 Use the httpd cookbook
  • Part 5 Inspec Integration Tests with Kitchen and Vagrant
  • Part 6 Build an AWS Infrastructure with Terraform

Requirements

This project uses the following software:

• Vagrant
• Virtualbox
• Terraform
• Chefdk
• Test Kitchen
• Kitchen-ec2 plugin
• Inspec
• Chefspec
• Ruby 2.4

Chefdk ships with Ruby, Test Kitchen, Chefspec and Inspec but I wanted to also call them out explicitly. In addition, the kitchen-ec2 gem is required.

Assumptions

• The listed software is installed and working properly
• You have a working AWS account and an existing credentials file

Day 1 - Set up local development environment

Day 2 - Generate a basic webserver cookbook with Chef tools

Day 3 - Write failing unit tests

Day 4 - Write code to pass unit tests
