MongoDB

The Railway MongoDB database service allows you to provision and connect to a MongoDB database with zero configuration.

Deploy

Add a MongoDB database to your project via the CMD + K menu or by clicking the + New button on the Project Canvas.

Connect

Connect to MongoDB from another service in your project by referencing the environment variables made available in the Mongo service:

MONGOHOST
MONGOPORT
MONGOUSER
MONGOPASSWORD
MONGO_URL

Connecting externally

It is possible to connect to MongoDB externally (from outside of the project in which it is deployed), by using the TCP Proxy which is enabled by default.

Keep in mind that you will be billed for Network Egress when using the TCP Proxy.

Image

The MongoDB database service uses the Docker official mongo image.

Custom Start Command

The MongoDB database service starts with the following Start Command to enable communication over Private Network: mongod --ipv6 --bind_ip ::,0.0.0.0
