(library/mariadb)
in the docker-library/official-images GitHub
repo.
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.
docker run --name some-mariadb -e MYSQL_ROOT_PASSWORD=mysecretpassword -d mariadb
This image includes EXPOSE 3306 (the mysql/mariadb port), so standard
container linking will make it automatically available to the linked containers
(as the following examples illustrate).
Since MariaDB is intended as a drop-in replacement for MySQL, it can be used with many applications.
docker run --name some-app --link some-mariadb:mysql -d application-that-uses-mysql
docker run -it --link some-mariadb:mysql --rm mariadb sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$MYSQL_ENV_MYSQL_ROOT_PASSWORD"'
The MariaDB image uses several environment variables which are easy to miss. While
not all the variables are required, they may significantly aid you in using the
image. The variables use "MYSQL" since the MariaDB binary is mysqld.
This is the one environment variable that is required for you to use the MariaDB image. This environment variable should be what you want to set the root password for MariaDB to. In the above example, it is being set to "mysecretpassword".
These optional environment variables are used in conjunction to set both a MariaDB
user and password, which will subsequently be granted all permissions for the
database specified by the optional MYSQL_DATABASE variable. Note that if you
only have one of these two environment variables, then neither will actually do
anything - these two are meant to be used in conjunction with one another.
This optional environment variable denotes the name of a database to create. If
a user/password was supplied (via the MYSQL_USER and MYSQL_PASSWORD
environment variables) then that user account will be granted (GRANT ALL)
access to this database.
If there is no database when mariadb starts in a container, then mariadb will
create the default database for you. While this is the expected behavior of
mariadb, this means that it will not accept incoming connections during that
time. This may cause issues when using automation tools, such as fig, that
start several containers simultaneously.
This image is officially supported on Docker version 1.4.1.
Support for older versions (down to 1.0) is provided on a best-effort basis.
