MySQL

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

Connect

When you run railway run in a project with the MySQL plugin installed, we inject several environment variables.

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

Many libraries will automatically look for the MYSQL_URL variable and use it to connect to MySQL. You can also manually use these variables however you like.

Image

The MySQL plugin uses the mysql:8 docker image.
