+# Metabase on VPC
+
+This example shows how to deploy a Metabase instance on Serverless Containers that connects to a PostgreSQL database running in a private network. The setup uses Terraform to manage the infrastructure.
+
+## Prerequisites
+
+- A Scaleway account
+- [Terraform](https://www.terraform.io/downloads.html) installed
+
+## Setup
+
+Deploy the PostgreSQL database and private network:
+
+```bash
+cd containers/vpc-metabase
+terraform init
+terraform apply
+```
+
+After, the deployment, you can find the Metabase URL in the output:
+
+```bash
+terraform output metabase_container_url
+```
+
+That's it! You can now access your Metabase instance at the provided URL 🎉. Please refer to the official [Metabase documentation](https://www.metabase.com/docs/latest/) for more information.
