Terraform workshop HoGent

This repository contains the IaC (infrastructure as code) for the Terraform workshop for HoGent during the Tech & Trend days (February 16, 2023).

Goal of this workshop

The goal of this workshop is to deploy an immutable (not possible to change after creation) webserver. We will have a first hands-on with Terraform and run some basic commands. We will use Google Cloud as cloud provider to apply this infrastructure.
