Terragrunt, Terraform & Python

(Based off of the awesome work at https://github.com/alpine-docker/terragrunt, Thank you guys!)

Home

https://github.com/abiydv/terragrunt

Included Tools

• Latest Terraform
• Latest Terragrunt
• Python 3.9 (Alpine based)

Motivation

The Terraform AWS Lambda module needs python to be available to build the deployment packages. Most of the other lean terragrunt/terraform images don't provide python out of the box.

Tags

latest tag will always have the latest Terraform and Terragrunt version. Terraform release tag is carried over as the image tag.

Updates

Terraform and Terragrunt version updates are automatic. Python version, however, is pinned to 3.9-alpine at the moment. build.sh needs an update to use a different python version.

GitHub actions workflow runs every Monday at 00:00 hrs. If there is a new Terragrunt version available, a new build is kicked off. This creates a new image with the latest Terraform version as its tag.

Past build logs are available under the Actions tab (upto the standard GitHub retention limit, of course).

Run

A simple example

docker --rm -v `pwd`:/apps abiydv/terragrunt:latest terragrunt run-all init

Notes -

• You can also mount your .ssh directory to /root/.ssh in case you are using modules from any private repo.
• Not using the -d flag allows you to inspect the terragrunt output on the console.
• terragrunt run-all init command above is just an example, it can be replaced by the usual terraform/terragrunt commands as required.
