Full Description

CentOS v7 with MariaDB v10

This image includes an RPM installation of MariaDB v10 from the MariaDB repository.

In addition, I've added the hostname, and sysvinit-tools packages to provide the ability for the DB instance to refer to its own hostname, and to use pidof.

Securing the DB instance is performed using the packaged script 'mysql_secure_installation'. Anonymous connections, remote connections are both disabled by default, and the test DB removed.

Credentials

The all privilege user in the DB is root
The credential is set to toor

Do NOT go to production with this image and the above default set.

Usage

I designed the image to be self-sufficient at runtime requiring little additional configuration once started.

Starting a fresh container (with NAT) only requires the following:

docker run -P kriation/centos7-mariadb10

I've added a script in the image that generates a privileged grant, and flushes DB privileges making it active immediately.
The script attempts to retrive an IP from three variables. In order of precedence, they are: $DBGRANTIP, $1 argument to grant.sh, and lastly, the ip of docker0.

docker exec [container_name] /con/context/grant.sh [optional:ip]

Once the grant is complete, you will be able to connect to the service with your favorite database administration tool on the NAT'd port assigned to your new container.

TODO

  • Organize MariaDB logging
  • Add customizations to instance in my.cnf
  • More when I think of it...
