MariaDB 10 on CentOS-7 with UTF8 defaults
Full Description

MariaDB 10 Docker Image (Centos7)

This is a MariaDB 10 Docker million12/mariadb image. Built on top of official centos:7 image. Inspired by Tutum's tutum/mariadb image.

Note: be aware that, by default in this container, MariaDB is configured to use ~1GB memory (innodb_buffer_pool_size in tuning.cnf). If you try to run it on node with less memory, it will fail.

Please use tags on Docker Hub for different versions.


Run the image as daemon and bind it to port 3306:
docker run -d -p 3306:3306 million12/mariadb

Run the image as daemon and specify MariaDB version 10.2:
docker run -d million12/mariadb:10.2

The first time that you run your container, a new user admin with all privileges will be created in MariaDB with a random password. To get the password, check the logs of the container by running:
docker logs <CONTAINER_ID>

You will see an output like the following:

    You can now connect to this MariaDB Server using:

        mysql -uadmin -pCoFlnc3ZBS58 -h<host>

    Please remember to change the above password as soon as possible!       
    MariaDB user 'root' has no password but only allows local connections

In this case, CoFlnc3ZBS58 is the password assigned to the admin user.

Custom Password for user admin

If you want to use a preset password instead of a random generated one, you can set the environment variable MARIADB_PASS to your specific password when running the container:

docker run -d -p 3306:3306 -e MARIADB_PASS="mypass" million12/mariadb

Data volumes

MariaDB stores data in /var/lib/mysql location. Mount a volume
to that location - below is an example with docker-compose how to do that:

version: '2'


    image: million12/mariadb:latest
      - dbdata:/var/lib/mysql
