MariaDB 11.4 on Ubuntu 24.04 LTS

What's included

• MariaDB 11.4 LTS from the official MariaDB repository
• Ubuntu 24.04 LTS with automatic security updates
• Trusted Launch: Secure Boot + vTPM supported
• Unique per-VM root password generated at first boot — no shared password in the image
• Auto-mounts an attached data disk on first boot
• Azure Monitor / Defender for Cloud ready

Quick start

1. SSH into the VM with the username and key you chose at deploy.
2. MariaDB runs as the `mariadb` systemd service on port 3306; the in-image ufw allows 3306, the NSG does not until you open it.
3. Connect locally with `mariadb -u root -p` using the generated password (command below), create your application user and schema, then open 3306 to your app tier only.

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /root/.mariadb-initial-password

This is the MariaDB root password set at first boot (root@localhost is switched to password auth, so plain `sudo mariadb` is refused). Connect with `mariadb -u root -p`, change it with ALTER USER, and delete the file once stored securely.
