Chainguard Container for mariadb

MariaDB is one of the most popular open source relational databases.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/mariadb:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Using MariaDb

The default MariaDB port is 3306. To run with Docker and allow empty passwords:

$ docker run -p 3306:3306 --rm -e MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=1 cgr.dev/chainguard/mariadb

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following command:

'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

Users and Directories

By default, this image runs as a non-root user named mysql with a uid of 65532.

Environment Variables

You can use environment variables to create a new database and user upon initialization, and also to set up the root account password.

• MARIADB_ROOT_PASSWORD: Sets the password for MariaDB's root superuser account. If this variable is not set, you'll need to use either MARIADB_RANDOM_ROOT_PASSWORD or MARIADB_ALLOW_EMPTY_ROOT_PASSWORD in order to initialize the database successfully.
• MARIADB_RANDOM_ROOT_PASSWORD: A non-zero value sets up a random password for the root superuser account.
• MARIADB_ALLOW_EMPTY_ROOT_PASSWORD: A non-zero value allows for an empty root password.
• MARIADB_DATABASE: Creates a new database upon initialization.
• MARIADB_USER: Together with MARIADB_PASSOWORD, this environment variable can be used to create a new database user and grant them full access to the database defined by MARIADB_DATABASE.
• MARIADB_PASSWORD: This should be used in conjunction with the MARIADB_USER environment variable to set up the database user's password.

Docker Compose Example

This docker-compose.yaml sets up a MariaDB database with a default database and user. Other services can be added to create a local multi-node environment for development and tests.

version: "3.7"
services:
  mariadb:
    image: cgr.dev/chainguard/mariadb
    restart: unless-stopped
    environment:
      MARIADB_RANDOM_ROOT_PASSWORD: yes
      MARIADB_USER: user
      MARIADB_PASSWORD: password
      MARIADB_DATABASE: test
    ports:
      - 3306:3306
    volumes:
      - ./:/app
    networks:
      - wolfi

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
