Terraform+Ansible Example

This repository is the near-simplest example of deploying an provisioning a web server on Amazon Web Services (AWS), using Terraform and Ansible. Based on:

• Terraform's Basic Two-Tier AWS Architecture example
• AWS's VPC with a Single Public Subnet example

Details

This repository sets up:

• A VPC
• A subnet
• An internet gateway
• A security group
• An SSH key pair
• A publicly-accessible EC2 instance
• Within the instance:
  • Python 2 (for Ansible)
  • Nginx

Setup

1. Install the following locally:
   • Terraform >= 0.10.0
   • Terraform Inventory
   • Python 2
   • pip
2. Set up AWS credentials in ~/.aws/credentials.
   • The easiest way to do so is by setting up the AWS CLI.
3. Ensure you have an SSH public key at ~/.ssh/id_rsa.pub.
   • How to generate

Usage

export AWS_DEFAULT_REGION=us-east-1

./deploy.sh

More information about the AWS environment variables. If it is successful, you should see an address printed out at the end. Visit this in your browser, and the page should say "Welcome to nginx!"

Notes

• ./deploy.sh is idempotent.
• Information about overriding the Terraform variables.
