MySQL Overview

Secure your stack with a hardened MySQL image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Try It Out

Take the Minimus MySQL image for a test run. The following command will set the root password to Minimus! but you can set any password you want:

docker run --name minimus-mysql \
    -e MYSQL_ROOT_PASSWORD=Minimus! -d \
    reg.mini.dev/mysql

Start a shell in your container:

docker exec -it minimus-mysql sh

Then log into the database:

mysql -u root -p

Submit the password you set when you ran the container. (In our example, it's Minimus!.) Once logged in, you should see MySQL status messages such as:

> Welcome to the MySQL monitor.  Commands end with ; or \g.
> Your MySQL connection id is 9
> Server version: 9.3.0 Source distribution
> 
> Copyright (c) 2000, 2025, Oracle and/or its affiliates.
> 
> Oracle is a registered trademark of Oracle Corporation and/or its
> affiliates. Other names may be trademarks of their respective
> owners.
> 
> Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Ready to interact with your MySQL server?

You should see the mysql> prompt of the MySQL shell. For our example, we will pass a command to list all databases:

show databases;

Note that the semicolon ; marks the end of the command. If you drop it, you will see a continuation prompt (->) to add more input.

MySQL will print database metadata. For example:

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.01 sec)

Run MySQL with Docker Compose

You can use a compose.yaml file to configure the MySQL database and set the appropriate environment variables.

The following variables are commonly used:

MYSQL_USER and MYSQL_PASSWORD - Create a new user and set its password
MYSQL_ALLOW_EMPTY_PASSWORD - Start the container without a root user password
MYSQL_DATABASE - Create a new empty database
MYSQL_ROOT_PASSWORD_FILE - instead of passing sensitive info in the command line you can provide a path to password file

Technical Considerations

The MySQL image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

MySQL built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks. The public image runs as root.
Listens on but does not expose the default ports: 3306/tcp and 33060/tcp. The public image listens on and exposes those ports by default.
The image does not have a default volume. The public image defaults to /var/lib/mysql.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
