Install MariaDB

  • Host network

Run the following command to create a container for MariaDB that uses host network:

docker run -d --name=mariadb --restart=always --network=host \
    -v /opt/mariadb/data:/var/lib/mysql \
  • User-defined bridge network

User-defined bridge network can be used for listening on different port. By default, MariaDB service is listening on port 3306. It can be changed with -p option.

docker network create app-net
docker run -d --name=mariadb --restart=always --network=app-net \
    -p 8080:3306 \
    -v /opt/mariadb/data:/var/lib/mysql \

Note: don't forget to change root password.

Testing MariaDB

Run the following command to open the MariaDB client and enter password:

docker exec -it mariadb mariadb -u root -p -e "SHOW DATABASES"

The command outputs all databases on server:

| Database           |
| information_schema |
| mysql              |
| performance_schema |
| sys                |

Uninstall MariaDB

To completely remove MariaDB, remove its container:

docker rm --force mariadb

Remove MariaDB image:

docker rmi mariadb

You can also remove MariaDB data:

sudo rm -rf /opt/mariadb

If a user-defined bridge network was created, you can delete it as follows:

docker network rm app-net
