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] [email protected][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]
