Red Hat's Universal Base Image (UBI) only includes a subset of RHEL packages, leaving out databases like MariaDB, PostgreSQL, and MySQL, plus many other tools. A no-cost Red Hat Developer subscription unlocks the full RHEL package catalog for container development and testing. Subscription access can be enabled automatically via a subscribed Linux host using subscription-manager, or through Podman Desktop with the Red Hat Account extension. A practical example demonstrates building a UBI10 container that installs MariaDB, showing the difference between unsubscribed and subscribed build outputs.
