To get Supabase up and running with Terraform for Infrastructure as Code (IaC), you'll need a few things:

• A local development setup with Terraform installed
• A Supabase account
• A PostgreSQL server hosted on Supabase

First things first, let's make sure Terraform is installed on your machine. You can check by running:

terraform -v

If it's not installed yet, just follow the instructions on the official HashiCorp learn website.

Log into your Supabase account and start a new project. Be sure to pick PostgreSQL for the database, since that's what Supabase uses.

After your database is set up, gather the following details from the database settings:

• Public Database URL
• PostgreSQL service credentials

Next, create a new Terraform configuration file in your local development environment. This file will tell Terraform how to create the resources needed to connect and interact with your PostgreSQL server on Supabase. Use the "pg" provider in the configuration file to let Terraform talk to your PostgreSQL database.

provider "pg" {
  host             = var.PGHOST
  port             = var.PGPORT
  username         = var.PGUSER
  password         = var.PGPASSWORD
  sslmode          = "require"
  connect_timeout  = 15
}

Use resource blocks to define what resources you want to create. These blocks can be used to create tables, fill them with data, and more. Here's an example of how to create a table:

resource "pg_schema" "my_schema" {
  name = "my_schema"
}

resource "pg_table" "my_table" {
  name = "my_table"
  schema = pg_schema.my_schema.id
}

Now, run the terraform init command in your terminal to initialize your Terraform configuration. This step installs the necessary provider plugins. After that, run terraform apply to apply the Terraform configuration and create the specified resources. Terraform will ask for confirmation before proceeding and show an execution plan.

Once you've reviewed and approved the execution plan, the specified resources will be created in your Supabase PostgreSQL database. You can now manage your Supabase infrastructure using your Terraform configuration.

This is a simple demo of integrating Supabase with Terraform for IaC. You might enhance it to meet your particular infrastructure needs according to database requirements.
