openstreetmap-tile-server

This container allows you to easily set up an OpenStreetMap PNG tile server given a .osm.pbf file. It is based on the latest Ubuntu 18.04 LTS guide from switch2osm.org and therefore uses the default OpenStreetMap style.

Setting up the server

First create a Docker volume to hold the PostgreSQL database that will contain the OpenStreetMap data:

docker volume create openstreetmap-data

Next, download an .osm.pbf extract from geofabrik.de for the region that you're interested in. You can then start importing it into PostgreSQL by running a container and mounting the file as /data.osm.pbf. For example:

docker run -v /absolute/path/to/luxembourg.osm.pbf:/data.osm.pbf -v openstreetmap-data:/var/lib/postgresql/10/main overv/openstreetmap-tile-server import

If the container exits without errors, then your data has been successfully imported and you are now ready to run the tile server.

Running the server

Run the server like this:

docker run -p 80:80 -v openstreetmap-data:/var/lib/postgresql/10/main -d overv/openstreetmap-tile-server run

Your tiles will now be available at http://localhost:80/tile/{z}/{x}/{y}.png. If you open leaflet-demo.html in your browser, you should be able to see the tiles served by your own machine. Note that it will initially quite a bit of time to render the larger tiles for the first time.

Preserving rendered tiles

Tiles that have already been rendered will be stored in /var/lib/mod_tile. To make sure that this data survives container restarts, you should create another volume for it:

docker volume create openstreetmap-rendered-tiles
docker run -p 80:80 -v openstreetmap-data:/var/lib/postgresql/10/main -v openstreetmap-rendered-tiles:/var/lib/mod_tile -d overv/openstreetmap-tile-server run

Performance tuning

The import and tile serving processes use 4 threads by default, but this number can be changed by setting the THREADS environment variable. For example:

docker run -p 80:80 -e THREADS=24 -v openstreetmap-data:/var/lib/postgresql/10/main -d overv/openstreetmap-tile-server run
