Ansible, Packer, and Terraform Demo

This project combines Ansible, Packer, and Terraform to show how you can automagically script and deploy a server with no manual configuration. In case you're unfamiliar with these 3 tools:

• Ansible - Automates server configuration
• Packer - Builds images of a configured server, but doesn't actually deploy it
• Terraform - Handles deploying an actual server

Overview

This project creates a Digital Ocean droplet that runs a local version of the website https://growlerfriday.com - which is pulled down from its GitHub repo and run using nginx.

If you edit your /etc/hosts file to point growlerfriday.com to the IP address of the created droplet, it will work.

Usage

Prior to running, make sure you have both packer and terraform installed.

git clone https://github.com/alkrauss48/ansible-packer-terraform-demo.git
cd ansible-packer-terraform-demo

# Set the variables in the .env file. At a minimum, this includes:
# * DIGITAL_OCEAN_API_TOKEN
# * SSH_FINGERPRINT

make packer-build
# This will take about 5 minutes. Copy the Snapshot ID you get at the end

make terraform-init
# Only have to do this once

make terraform-plan
<enter Snapshot ID from packer-build command>

# If all looks good, then:

make terraform-apply
<enter Snapshot ID from packer-build command>
# This will take about a minute

# Done!
