Summary

• Terraform provisions an EC2 auto scaling group.
• Chef configures a basic apache web server.

Usage

1. Clone this repository locally.
2. Ensure your AWS API access keys are defined in ~/.aws/credentials.
3. Update terraform/terraform.tfvars variables with your AWS account ID and other optional parameters.
4. Use Terraform to provision infrastructure.

$ cd terraform/
$ terraform apply -target=module.vpc
$ terraform apply -target=module.apache

5. SSH into server and run ChefSpec tests.

$ ssh ubuntu@<ec2_dns>
$ cd /srv/playground/chef/apache
$ sudo chef exec rspec

6. Stress the CPU, which triggers ASG to spin up 2nd server.

$ stress -c 8

7. Afterwards, use Terraform to destroy infrastructure.

$ terraform destroy -target=module.apache
$ terraform destroy -target=module.vpc
