Packer Basic Example

This folder contains a very simple Packer template to demonstrate how you can use Terratest to write automated tests for your Packer templates. The template just creates an up-to-date Ubuntu AMI by running apt-get update and apt-get upgrade.

Check out test/packer_basic_example_test.go to see how you can write automated tests for this simple template.

Note that this template doesn't do anything useful; it's just here to demonstrate the simplest usage pattern for Terratest. For slightly more complicated, real-world examples of Packer templates and the corresponding tests, see packer-docker-example and terraform-packer-example.
