MariaDB on Ubuntu Server 22.04 LTS offers a hardened, optimized open-source database environment tailored for secure, high-performance cloud workloads. Built on the latest Ubuntu LTS and the robust MariaDB engine, this image is tuned for long-term production use.

Security hardening includes:

Anonymous users and test databases removed
Remote root login disabled
Root password unset by default – must be securely configured after deployment
Strict password policy: minimum 8 characters, includes digit, upper/lower case, and special symbol

Configuration enhancements:

DNS lookups disabled – faster and more secure client connections
Symbolic links disabled to prevent filesystem exploits
LOAD DATA LOCAL INFILE disabled to block unauthorized file access
Listener bound to localhost – no external access unless configured
Slow and error logs redirected to structured log files

Performance and storage tuning:

Higher max connections and open table cache for scalable concurrency
Slow query log enabled with 2-second threshold
UTF8MB4 character set and Unicode-aware collation – full language and emoji support
InnoDB: Direct I/O, 512MB buffer pool, one-file-per-table, sync log flush, 10-day log retention
Aria engine: expanded buffer for efficient temporary tables

Backup tool included: A dedicated MariaDB backup utility is pre-installed, requiring minimal configuration. Optimized for fast change capture, low-latency transfers, and consistent snapshot integrity.

Password customization: To adjust password rules, edit /etc/mysql/init_custom.sql with root access.

This image is ideal for:

Web apps, SaaS platforms, and microservices
Enterprise-grade production deployments
CI/CD environments with parity to staging
Multilingual applications with strict security needs

Start your hardened MariaDB instance in minutes – secure, performant, and ready for the enterprise.
