Rotating keys in CARTO Self-Hosted is a simple process to ensure the security of your custom buckets, BigQuery OAuth connections, Google basemaps and custom LDS API Keys. Below are instructions for both the single VM deployment and orchestrated container deployment versions.

## Single VM deployments (Docker Compose)

1. Navigate to your CARTO Self-Hosted installation directory.
2. Inside the <mark style="color:orange;">customer.env</mark> file, find and update the keys related to [custom buckets](/carto-self-hosted/guides/guides/configure-your-own-buckets.md), [BigQuery OAuth connections](/carto-self-hosted/guides/guides/enable-bigquery-oauth-connections.md), [Google basemaps](/carto-self-hosted/guides/guides/enable-google-basemaps.md) and LDS API Keys.
3. Save the changes to the <mark style="color:orange;">customer.env</mark> file.
4. Restart your self-hosted deployment using the following command:

   ```bash
   docker-compose down && docker-compose up -d
   ```

Remember to perform these steps with caution, ensuring minimal downtime for your CARTO Self-Hosted deployment.
