# Environment Variables

> Server-side configuration.

The binary executable can also be configured using environment variables.

Note, you must opt-in to this by setting the `-env` flag when starting the server. This mode of configuration is useful for containerized environments like Docker where it is difficult to pass command-line arguments.

<Info>If you are using the pre-built Docker images, this flag has already been set.</Info>
