Quickstart

Note that you must have terraform/terragrunt binaries installed on your machine

The examples directory contains 4 modules. 2 of them are terraform and 2 are terragrunt.

Oh no! It appears some of them have some problems. Let's see exactly what is going on. Clone this repository and give it a try.

git clone https://github.com/elementtech/terracove.git
cd terracove
terracove --minimal --junit --json --html . 
# . == examples == examples/terraform examples/terragrunt

Open the terracove.xml, terracove.json or terracove.html and observe the results. You should see the following:
