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 git@github.com: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
