Yes in spirit, but it is a Docker Compose stack rather than one container. That works better for my set up. IOW nginx/MapLibre/PMTiles, the SQLite search service, and BRouter are separate containers, but they are managed as one project. Like this -

pi-maps          → nginx + MapLibre + PMTiles
pi-maps-search   → Python + SQLite FTS5
pi-maps-brouter  → BRouter
