Question 1

What is an OSM tile server?

Accepted Answer

It's a server that renders and serves the small map images (tiles) that map libraries stitch together to display a map, using OpenStreetMap's open data. When Leaflet or a similar library draws a map, it loads many square PNG tiles at different zoom levels — this server generates and serves those for a region you choose, entirely on your own hardware, at a standard /tile/{z}/{x}/{y}.png endpoint.

Question 2

Which port does it use and how do I use the tiles?

Accepted Answer

It runs on host port 8317. After the region imports, point a map library like Leaflet at the tile endpoint http://your-server:8317/tile/{z}/{x}/{y}.png as its tile layer, and it will render your maps. Note that this is host port 8317, not the 8080 you might expect from the container. For a public app, put a reverse proxy with TLS in front.

Question 3

How do I choose which region to import?

Accepted Answer

You supply a Geofabrik extract URL — a .pbf file for a country, region, or continent from download.geofabrik.de. The installer defaults to Monaco for a fast test, but you set it to whatever area your app needs. The crucial factor is size: match the region to your hardware, because a large area needs far more RAM and disk and takes much longer to import than a small one.

Question 4

Why is the first start so slow?

Accepted Answer

On first run the server imports your chosen region's data into its database and prepares rendering, which is genuinely heavy work. A small region like Monaco takes a few minutes, but a large country can take hours and a lot of RAM. Watch the container logs to follow the import — a first start that seems stuck is almost always the import in progress, not a failure.

Question 5

How does it fit with Nominatim and GraphHopper?

Accepted Answer

They're the three parts of a full self-hosted maps stack. This tile server draws the map itself, Nominatim provides geocoding (turning addresses into coordinates and back), and GraphHopper provides routing (turn-by-turn directions). Together they replace the display, search, and directions of a commercial map platform like Google Maps, all on your own servers using OpenStreetMap data.
