Versioning

This image follows the Semantic Versioning pattern.

• MAJOR version - Changes on Base Image version (1.0.0 to 2.0.0)
• MINOR version - Changes on MariaDB version (10.4.13 to 10.4.14)
• PATCH version - Package updates and other non breaking changes on the image
• DRAFT version - Unstable build for review (Optional)

Version Mapping

Version	1.0	1.1	2.0
Base Image	1.x.x	1.x.x	2.x.x
MariaDB	10.4.13	10.4.14	10.4.13

When Base Image gets upgraded the major version is incremented, when MariaDB gets upgraded the minor version is incremented.

The version tags are the same as the repository versioning tags but without the v. The test version is only for build purposes, it should not be pulled.

The arch can be one of the supported architectures described below.

Volumes and Ports

It exposes a single volume at /config where it keeps the configuration, logs and database files.

Also a single port is exposed at 3306 to allow external connections to the database.

Bootstrapping the database

It's possible to bootstrap the database executing sql files the first time the container starts, just need to put the sql files in:

/config/initdb.d/

The result is the same as setting the REMOTE_SQL environment variable but in this case it uses local files instead of http(s).

Start Container

docker run \
  -e PUID=1000 \
  -e PGID=1000 \
  -e MYSQL_ROOT_PASSWORD=password.123 \
  -p 3306:3306 \
  -v $PWD:/config \
  fabiodcorreia/mariadb

Logging

By default the container will log to the stdout (console), so it will be handled by the docker logging system, if logging to a file is preferred that can be changed with the environment variable LOG_TO_FILE, when it' set to true it will log to /config/log/mysql/error.log.
