+# Database Docker with Web Proxy
+
+This role builds on `cmp-db-docker` by adding a reverse-proxy frontend for HTTP access to your database service.
+
+## Features
+
+- **Database Composition**  
+  Leverages the `cmp-db-docker` role to stand up your containerized database (PostgreSQL, MariaDB, etc.) with backups and user management.
+
+- **Reverse Proxy**  
+  Includes the `srv-web-proxy-domain` role to configure a proxy (e.g. nginx) for routing HTTP(S) traffic to your database UI or management endpoint.
