MariaDB

MariaDB docker container

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.[5] Contributors are required to share their copyright with the MariaDB Foundation.

How to use this image

When started MariaDB container will listen on port 3306.

Hosting a MariaDB instance on port 3306

sudo docker run -it -p 3306:3306 -d dperson/mariadb

Configuration

sudo docker run -it --rm dperson/mariadb -h

Usage: mariadb.sh [-opt] [command]
Options (fields in '[]' are optional, '<>' are required):
    -h          This help
    -t ""       Configure timezone
                possible arg: "[timezone]" - zoneinfo timezone for container

The 'command' (if provided and valid) will be run instead of mariadb

ENVIRONMENT VARIABLES

• SQL_ROOT_PASSWORD - Will set root password when initializing container
• SQL_ALLOW_EMPTY_PASSWORD - Allow empty passwords (bad idea)
• DATABASE - Will create DB when initializing container
• SQL_USER - Will create user when initializing container
• SQL_PASSWORD - Will be used in creating user above
• TZ - As above, configure the zoneinfo timezone, IE EST5EDT
• USERID - Set the UID for the DB user
• GROUPID - Set the GID for the DB user

Examples

Any of the commands can be run at creation with docker run or later with docker exec -it mariadb mariadb.sh (as of version 1.3 of docker).

Setting the Timezone

sudo docker run -it -p 3306:3306 -d dperson/mariadb -t EST5EDT

OR using environment variables

sudo docker run -it -p 3306:3306 -e TZ=EST5EDT -d dperson/mariadb

Will get you the same settings as

sudo docker run -it --name db -p 3306:3306 -d dperson/mariadb
sudo docker exec -it db mariadb.sh -t EST5EDT ls -AlF /etc/localtime
sudo docker restart db

Complex configuration

Example configs⁠

If you wish to adapt the default configuration, use something like the following to copy it from a running container:

sudo docker cp db:/etc/mysql /some/path

You can use the modified configuration with:

sudo docker run -it --name db -p 3306:3306 -v /some/path:/etc/mysql:ro \
            -d dperson/mariadb
