# Metabase on VPC
2+
3+
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.
4+
5+
## Prerequisites
6+
7+
- A Scaleway account
8+
- [Terraform](https://www.terraform.io/downloads.html) installed
9+
10+
## Setup
11+
12+
Deploy the PostgreSQL database and private network:
13+
14+
```bash
15+
cd containers/vpc-metabase
16+
terraform init
17+
terraform apply
18+
```
19+
20+
After, the deployment, you can find the Metabase URL in the output:
21+
22+
```bash
23+
terraform output metabase_container_url
24+
```
25+
26+
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.
