Running a full valhalla demo entirely self hosted!
Prerequisites
Must have docker and docker compose installed.
https://docs.docker.com/engine/install/ubuntu/
Hardware Requirements
The configuration for PostgreSQL has been tuned for a machine with 16 cores and 128 GB RAM. These config files should be adjusted if you are running this on a smaller machine.
See the osm2pgsql docs for more information on how to adjust this config.
Clone the demo app
git clone [email protected]:wcedmisten/valhalla-app.git
cd valhalla-app
git checkout self-hosted
cd ..
Build the demo app
docker compose build
Import the data
mkdir ./osm-pbf
cp /path/to/osm.pbf ./osm-pbf/region.osm.pbf
./import.sh
Run the apps
docker compose up
Postgres config
import-postgresql.conf is used for import. The main difference is that autovacuum is off.
run-postgresql.conf has it turned on. This config is tuned for my machine with 128 GB of RAM and 16 CPUs.
Pre-render tiles at low zoom
You may want to expand the parameters used to include higher zoom levels.
E.g. using -z 2 -Z 8 to pre-render up to level 8.
Increasing zoom levels will take exponentionally more time to render
and more space to store, but will provide a better experience for the user.
There are also better ways to render zoom levels that don't include ocean tiles that should be used instead.
docker exec -it tile-server bash
sudo -u _renderd render_list -t /data/tiles -a -z 2 -Z 3 -n 16
