This folder contains an example of how define infrastructure-as-code using Packer. The simple-web-server.json Packer template shows how to create an AMI containing a simple web server that you can deploy in AWS. The AMI is built on top of Ubuntu, has Ruby on Rails installed, and contains the code from the example-rails-app folder.

1. Install Packer.
2. Add your AWS credentials as the environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
3. Run packer build simple-web-server.json.
4. When the build is done, it'll output the ID of an AMI in us-east-2 that you can deploy. See the terraform-example-full folder for an example of how to deploy this AMI and run the Ruby on Rails app within it.
