This repository contains a Dockerfile for building a MariaDB image based on Debian. The image is configured to run MariaDB as a non-root user for security reasons.
Info : The mariadb in the container is a pre-build image so the user, password and the database, are created by default for a wordpress.
The Dockerfile installs MariaDB and other necessary packages on a Debian base image. It also sets up necessary directories and permissions for running MariaDB.
The docker-entrypoint.sh script is used to initialize the database and create a user when the container is started. The script checks if it's being run as root, and if so, uses gosu to step down from root to the mysql user.
Environment variables are used to configure the database. You can set the root password, database name, username, and password using the MYSQL_ROOT_PASSWORD, MYSQL_DATABASE, MYSQL_USER, and MYSQL_PASSWORD environment variables, respectively.
The following environment variables can be set when running the Docker container:
| ENV | Default value | Example | Description |
|---|---|---|---|
| MYSQL_ROOT_PASSWORD | credentials.md | myrootpassword | By default, the root password is randomly generated. You can specify a specific root password if required. |
| MYSQL_DATABASE | wordpress | mydatabase | The name of the first database. |
| MYSQL_USER | wpuser | myuser | The username first user. |
| MYSQL_PASSWORD | wpuser | mypassword | The password for the first user. |
You can run a container from this image using the following command:
docker run -d --name some-mariadb -p 3306:3306 nayeonyny/mariadb:latestCopyright (C) 2024 Ethan Besson
