tutum-docker-mariadb

Base docker image to run a MariaDB database server

MariaDB version

master branch maintains MariaDB from Ubuntu trusty official source. If you want to get different version of Mariad, please checkout 5.5 branch and 10.0 branch.

If you want to use MySQL, please check our tutum/mysql image: https://github.com/tutumcloud/tutum-docker-mysql

Usage

To create the image tutum/mariadb, execute the following command on the tutum-docker-mariadb folder:

    docker build -t tutum/mariadb .

To run the image and bind to port 3306:

    docker run -d -p 3306:3306 tutum/mariadb

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 -pxVN33tWOhM3u -h<host> -P<port>

    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, xVN33tWOhM3u is the password assigned to the admin user.

Done!

Setting a specific password for the admin account

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" tutum/mariadb

Mounting the database file volume from other containers

One way to persist the database data is to store database files in another container. To do so, first create a container that holds database files:

docker run -d -v /var/lib/mysql --name db_vol -p 22:22 tutum/ubuntu-trusty 

This will create a new ssh-enabled container and use its folder /var/lib/mysql to store MariaDB database files. You can specify any name of the container by using --name option, which will be used in next step.

After this you can start your MariaDB image using volumes in the container created above (put the name of container in --volumes-from)

docker run -d --volumes-from db_vol -p 3306:3306 tutum/mariadb
