MariaDB

A shared MariaDB instance running in the Docker stack, used as backing storage for the self-hosted apps that need MySQL-compatible storage rather than each app bundling its own database container. It currently backs phpIPAM and Nextcloud.

It has no web UI of its own, so there’s nothing to screenshot here, it’s pure plumbing. It’s deployed through the generic Compose stack, with the underlying volume data covered by docker_data_backup.
