This repository is the near-simplest example of deploying an provisioning a web server on Amazon Web Services (AWS), using Terraform and Ansible. The Terraform part is based on their Basic Two-Tier AWS Architecture example.

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

1. Install the following locally:
   • Terraform
   • 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

./deploy.sh

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!"

• ./deploy.sh is idempotent.

• If you have multiple AWS accounts/profiles, run with

  AWS_PROFILE=something ./deploy.sh

• You can override any of the Terraform variables using a terraform.tfvars file under the terraform/ directory.
