A Terraform module for building a public/private DNS pair in AWS.

This consists of:

• A public DNS zone
• A private DNS zone

To use the module, include something like the following in your terraform configuration:

module "dns-zones" {
  source = "infrablocks/dns-zones/aws"

  domain_name = "jimmythompson.co.uk"
  private_domain_name = "jimmythompson.net"

  # Default VPC
  private_zone_vpc_id = "vpc-6e12c307"
  private_zone_vpc_region = "us-east-2"
}

In order for the build to run correctly, a few tools will need to be installed on your development machine:

• Ruby (2.3.1)
• Bundler
• git
• git-crypt
• gnupg
• direnv

Installing the required tools is best managed by homebrew.

To install homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then, to install the required tools:

# ruby
brew install rbenv
brew install ruby-build
echo 'eval "$(rbenv init - bash)"' >> ~/.bash_profile
echo 'eval "$(rbenv init - zsh)"' >> ~/.zshrc
eval "$(rbenv init -)"
rbenv install 2.3.1
rbenv rehash
rbenv local 2.3.1
gem install bundler

# git, git-crypt, gnupg
brew install git
brew install git-crypt
brew install gnupg

# direnv
brew install direnv
echo "$(direnv hook bash)" >> ~/.bash_profile
echo "$(direnv hook zsh)" >> ~/.zshrc
eval "$(direnv hook $SHELL)"

direnv allow <repository-directory>

To provision module infrastructure, run tests and then destroy that infrastructure, execute:

./go

To provision the module contents:

./go deployment:harness:provision[<deployment_identifier>]

To destroy the module contents:

./go deployment:harness:destroy[<deployment_identifier>]

To generate an SSH key pair:

ssh-keygen -t rsa -b 4096 -C [email protected] -N '' -f config/secrets/keys/bastion/ssh
