docker-mariadb-centos7

A dockerfile with few shell scripts to run a MariaDB database server in Centos 7.x based container.

Usage

To create the image docker-mariadb-centos7/mariadb, execute the following command on the docker-mariadb-centos7 folder:

    docker build -t docker-mariadb-centos7/mariadb .

To run the image and bind to port 3306:

    docker run -d -p 3306:3306 docker-mariadb-centos7/mariadb

The first time that you run your container, a new user root 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 -uroot -p<password> -h<host> -P<port>
    ========================================================================

Setting a specific password for the root 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" docker-mariadb-centos7/mariadb
