MariaDB is the open source successor to MySQL.

Additional MariaDB Logging

During the course of development, it may be necessary to enable either query logging or slow query logging. To do so, set the environment variables MARIADB_LOG_SLOW or MARIADB_LOG_QUERIES. This can be done in docker-compose.yml.

Connecting to MySQL container from the host

If you would like to connect to your MySQL database inside the Docker container with an external tool like Sequel Pro, MySQL Workbench, HeidiSQL, DBeaver, just plain old mysql-cli or anything else, here's how to get the IP and port info.

Get published MySQL port from the container

By default, Docker assigns a randomly published port for MySQL during each container start. This is done to prevent port collisions.

To get the published port via docker:

Run: docker port [container_name].

$ docker port drupal_example_mariadb_1
3306/tcp ->

Or via docker-compose inside a Drupal repository:

Run: docker-compose port [service_name] [interal_port].

$ docker-compose port mariab 3306

Setting a static port (not recommended)

During development, if you are using an external database tool, it may become cumbersome to continually check and set the MySQL connection port.

To set a static port, edit your service definition in your docker-compose.yml.

      - "33772:3306" # Exposes port 3306 with a 33772 on the host port. Note by doing this you are responsible for managing port collisions`.


By setting a static port you become responsible for managing port collisions.

Connect to MySQL

Now you can use these details to connect to whatever database management tool you'd like.
