MySQL

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

Connect

There are two ways to connect to a MySQL database:

• Add a Reference Variable to a service
• Run railway connect to start a mysql shell

The following variables can be referenced in your services:

• MYSQLHOST
• MYSQLPORT
• MYSQLUSER
• MYSQLPASSWORD
• MYSQLDATABASE
• MYSQL_URL

Connect to your MySQL container using your library of choice and supplying the appropriate environment variables.

Image

The MySQL database service uses the mysql:8 docker image.

Changing System Variables

We do not support changing System Variables for MySQL at the moment.
