MariaDB stack documentation

MariaDB can be configured with the following environment variables

External access

There are two ways to connect to a MariaDB server externally: publish port or set up an SSH tunnel.

Publish port

Publish MariaDB's port (3306) from stack configuration page to a dynamic node port and connect as:

mysql -h=[IP] -P[PORT] -u[USER] -p[PASSWORD] [DATABASE]

Where [PORT] is the generated node port (you can find it on a service page App Instance > Stack > MariaDB) and [IP] is the IP of the server where app instance deployed (or use the server hostname node-[SERVER UUID].wod.by).

Set up tunnel

If you deploy MariaDB as a service inside of a stack that comes with an SSHD container, you can set up a secure tunnel:

  1. Set up SSH tunnel on port 53306 (you can change it). You can find [SSH Port] on Instance > Stack > SSH page. For MariaDB (port 3306 by default) use the following command: 
    ssh -L 53306:mariadb:3306 -p [SSH Port] wodby@[Server IP] -N
  2. Connect to the database via the tunnel on port 53306 (replace [tokens]): 
    mysql --protocol=TCP -P53306 -u[USER] -p[PASSWORD] [DATABASE]

Changelog

This changelog is for MariaDB stack on Wodby, to see image changes see tags description on repository page.

MariaDB updates

  • We strongly recommend to backup your database before upgrading your application stack
  • During MariaDB upgrade we run mysql-check and mysql-upgrade. This operation may take a few minutes for big databases

If your app has MariaDB 10.1 service and the app was created (or its stack was upgraded) after June 2018, you're actually running MariaDB 10.2 (see https://twitter.com/wodbycloud/status/1206943424861102081 for more details).
