Quickspin

This repo contains terraform code that will quickly:

Spin up a Chef server
Spin up a Chef Automate server
Set up reporting from the Chef server into Automate
Spin up an On-Prem Builder server and set up OAUTH with the Automate instance (OPTIONAL)
Spin up sample nodes to manage (OPTIONAL)

DISCLAIMER: This code was originally intended to quickly spin up a demo environment. There are most certainly optimizations that can and should be made if you were going to use this to spin up a stack for actual usage.

Translation: YMMV, and do your due dilligence if you are going to use this for anything other than a transient demo environment.

Modules

Base

This module is responsible for spinning up the Chef server, the Chef Automate server, the On-Prem Builder server, and them taking care of all the plumbing to connect everything up. These servers are built with the latest available CentOS AMIs, and are provisioned with the latest versions of the various Chef products.

NOTE: There is functionality here that will automatically harvest the newly created user's key from the Chef server, and update a ~/.chef/knife-override.rb file. The intent here is to make the newly created stack immediately accessible via knife when the plan is completed. This functionality requires gsed in your path (installed via brew install gnu-sed), a keys directory should be located at ~/.chef/keys, and it also requires your knife.rb to be located at ~/.chef/knife.rb. Inside that file, you need to have the following block:

# Allow overriding values in this knife.rb
require 'chef/config'
knife_override = "#{home_dir}/.chef/knife-override.rb"
Chef::Config.from_file(knife_override) if File.exist?(knife_override)

If you want to use this:

make sure your knife.rb file and knife-override.rb file are located at ~/.chef
create a keys directory at ~/.chef/keys or override that path by setting a value for local_keys_directory in your terraform.tfvars
set harvest_key = true and update_knife_override = true in your tfvars file.

An example knife-override.rb is also included in this repo.

Centos Sample Nodes

This module controls spinning up CentOS sample nodes. It uses the latest available CentOS 7 image. Control wether or not these nodes spin up by using an integer value for the variable centos_sample_node_count.

RHEL Sample Nodes

This module controls spinning up RHEL sample nodes. It uses the latest available RHEL 7 image. Control wether or not these nodes spin up by using an integer value for the variable rhel_sample_node_count.

SLES Sample Nodes

This module controls spinning up SLES sample nodes. It uses the latest available SLES 7 image. Control wether or not these nodes spin up by using an integer value for the variable sles_sample_node_count.

Ubuntu Sample Nodes

This module controls spinning up Ubuntu sample nodes. It uses the latest available Ubuntu 18.04 LTS image. Control wether or not these nodes spin up by using an integer value for the variable ubuntu_sample_node_count.

Usage

Copy terraform.tfvars.example to terraform.tfvars.
- cp terraform.tfvars.example terraform.tfvars
Edit terraform.tfvars and use whatever values you need.
- vi terraform.tfvars
  - Note, this plan expects to create DNS entries w/ Route53. You will need to make sure to put in valid values for the DNS zone IDs. Adjust any other values accordingly.
Initialize and apply the plan.
- terraform init
- terraform apply
