Terrenv

Terraform has an assumption that your infrastructure would only be deployed once. But what if you wanted a staging or testing environment? You would have to manage state files and variable files yourself in different directories.

Terrenv is a simple tool that lets you switch environments seemlessly.

Install it with:

$ gem install terrenv

Run

$ terrenv init

and follow the instructions to generate a TerraformFile

$ terrenv init

will ask you some questions to setup your TerraformFile. You will need to run terrenv apply inorder to apply the settings.

$ terrenv apply

will take the configuration in the TerraformFile does a few steps for setup

1. Create directories for each environment labeled terraform-<environment>.
2. Setup your remote state-file configurations and pull down the state files from the S3 bucket and placed inside terraform-<environment>
3. Sets up your environment to the last environment specified on the TerraformFile

$ terrenv use <environment>

will switch the symlinks to point to the environment specified.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
