Simple docker image to run a MariaDB server

tutum-docker-mariadb

Base docker image to run a MariaDB database server

MariaDB version

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
