Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Container images.
MariaDB Server is one of the most popular database servers in the world. It's made by the original developers of MySQL and guaranteed to stay open source. Notable users include Wikipedia, WordPress.com and Google.
MariaDB turns data into structured information in a wide array of applications, ranging from banking to websites. It is an enhanced, drop-in replacement for MySQL. MariaDB is used because it is fast, scalable and robust, with a rich ecosystem of storage engines, plugins and many other tools make it very versatile for a wide variety of use cases.
MariaDB is developed as open source software and as a relational database it provides an SQL interface for accessing data. The latest versions of MariaDB also include GIS and JSON features.
- Minimal size only, minimal layers
- Memory usage is minimal on a simple install.

MYSQL_DATABASE: specify the name of the databaseMYSQL_USER: specify the User for the databaseMYSQL_PASSWORD: specify the User password for the databaseMYSQL_ROOT_PASSWORD: specify the root password for MariadbMYSQL_CHARSET: default charset (utf8) for MariadbMYSQL_COLLATION: default collation (utf8_general_ci) for Mariadb
It would be best to inject these as secrets in either kubernetes or swarm
When setting charset, also make sure to choose a collation otherwise it will be the default.

docker run -it --name mysql -p 3306:3306 -v /var/lib/mysql:/var/lib/mysql -e MYSQL_DATABASE=wordpressdb -e MYSQL_USER=wordpressuser -e MYSQL_PASSWORD=hguyFt6S95dgfR4ryb -e MYSQL_ROOT_PASSWORD=hguyFtgfR4r9R4r76 yobasystems/alpine-mariadb
It will create a new db, and set mysql root password (default is RaNd0MpA$$W0Rd generated by pwgen) unless the data already exists.
Many configuration options can be passed as flags to mysqld. This will give you the flexibility to customise the container without needing a .cnf file. For example, if you want to change the default encoding and collation for all tables to use UTF-8 (utf8mb4) just run the following:
docker run --name some-mariadb -e MYSQL_ROOT_PASSWORD=my-secret-pw -d yobasystems/alpine-mariadb --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_cicommand:
- --character-set-server=utf8
- --collation-server=utf8_bin
- --explicit-defaults-for-timestamp=1
The configuration file is located;
- /etc/my.cnf
- /etc/my.cnf.d/mariadb-server.cnf
When a container is started for the first time, a new database with the specified name will be created and initialised with the provided configuration variables. Furthermore, it will execute files with extensions .sh, .sql and .sql.gz that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. You can easily populate your mariadb services by mounting a SQL dump into that directory and provide custom images with contributed data. SQL files will be imported by default to the database specified by the MYSQL_DATABASE variable.
(Please pass your own credentials or let them be generated automatically, don't use these ones for production!!)
mysql:
image: yobasystems/alpine-mariadb
environment:
MYSQL_ROOT_PASSWORD: hguyFtgfR4r9R4r76
MYSQL_DATABASE: wordpressdb
MYSQL_USER: wordpressuser
MYSQL_PASSWORD: hguyFt6S95dgfR4ryb
expose:
- "3306"
volumes:
- /data/example/mysql:/var/lib/mysql
restart: always
The following is a docker swarm example, firstly create some secrets then create the service;
printf "hguyFtgfR4r9R4r76" | docker secret create MYSQL_ROOT_PASSWORD -
printf "wordpressdb" | docker secret create MYSQL_DATABASE -
printf "wordpressuser" | docker secret create MYSQL_USER -
printf "hguyFt6S95dgfR4ryb" | docker secret create MYSQL_PASSWORD -
printf "utf8mb4" | docker secret create MYSQL_CHARSET -
printf "utf8mb4_general_ci" | docker secret create MYSQL_COLLATION -
docker service create \
