Databases

Railway can support any type of Database service required for an application stack.

Databases can be deployed into a Railway project from a template, or by creating one through the service creation flow.

How Database Services work in Railway

Below are the core concepts to understand when working with databases in Railway.

Services

Railway services are containers deployed from a Docker Image or code repository, usually with environment variables defined within the service configuration to control the behavior of the service.

Volumes

When deploying a database service, data can be persisted between rebuilds of the container by attaching a Volume to the service.

TCP Proxy

To access a database service from outside the private network of a particular project, proxy traffic to the exposed TCP port by enabling TCP Proxy on the service.

Many database templates are available to Railway users, which ease the process of deploying a database service.
