Short Description¶
MariaDB is a community-developed fork of MySQL intended to remain free under the GNU GPL
What is MariaDB ?¶
MariaDB is a community-developed fork of the MySQL relational database management system intended to remain free under the GNU GPL.
Being a fork of a leading open source software system, it is notable for being led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle.
Contributors are required to share their copyright with the MariaDB Foundation.
The intent is also to maintain high compatibility with MySQL, ensuring a “drop-in” replacement capability with library binary equivalency and exact matching with MySQL APIs and commands. It includes the XtraDB storage engine for replacing InnoDB, as well as a new storage engine, Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.
How to use this image¶
Start a mariadb server instance
Starting a MariaDB instance is simple:
$ docker run --name some-mariadb -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mariadb:tag
where some-mariadb is the name you want to assign to your container, my-secret-pw is the password to be set for the MySQL root user and tag is the tag specifying the MySQL version you want.
See the list above for relevant tags. Connect to MySQL from an application in another Docker container
Since MariaDB is intended as a drop-in replacement for MySQL, it can be used with many applications.
This image exposes the standard MySQL port (3306), so container linking makes the MySQL instance available to other application containers. Start your application container like this in order to link it to the MySQL container:
$ docker run --name some-app --link some-mariadb:mysql -d application-that-uses-mysql
