Example Dockerised, Terraformed application deployment onto docker on bare metal

We're gonna run Quassel on bare metal in the most low-effort and high-reward enterprisey way possible. Why? Because we can.

Pre-requisites

We're gonna need some tools:

OpenTofu, the replacement for Terraform since Hashicorp changed the licence terms: https://opentofu.org/docs/intro/install/.
- As Tofu is a drop in replacement for Terraform, you can use Terraform if you prefer, and I'll refer to them interchangeably.

The main players:

The bit-actors:

docker.tf - Configures the Docker Provider for Tofu
inputs.tf - Where inputs to this deployment are defined and may have defaults set
outputs.tf - Where outputs from this deployment are defined, which will be output when we run tofu apply or tofu outputs
terraform.tf - Telling Terraform/ToFu what packages we need to run this deployment
.terraform.lock.hcl - Lock file for Terraform/ToFu, this is here to ensure that we're all using the same versions of the same packages
terraform.tfvars - Where we may set the variables defined in inputs.tf

When we run tofu apply:

Tofu will create a Docker network for our Quassel instance
Tofu will create a Postgres instance for our Quassel instance
Tofu will compile our Quassel instance image from the Dockerfile in the quassel directory
Tofu will create a Quassel instance using that image
Tofu will output the IP address of the Quassel instance and postgres instance

Did you give tofu apply a go yet?
