ghcr.io/gis-ops/docker-valhalla/valhalla:latest
https://download.geofabrik.de/north-america/canada.html

Docker image (docker-valhalla/valhalla) requires root privileged permission which sterms from non-existing user_id on host machine. It attempts to use sudo chmod overwriting file premission in the mounted path. A simpler solution is to create user_id, group_id on host and set proper folder permission to the path so that docker user_id is matched with host user_id of the mounted folder.

Solution

This repo is to implement non-root user so that the container can be deployed in Azure Container App and kubernetes.

Usage (local)

#
docker run --rm -p 8002:8002 \
  -v $PWD/gtfs_feeds:/gtfs_feeds  \
  -e build_transit=True -e tile_urls=https://download.geofabrik.de/north-america/canada/ontario-latest.osm.pbf --name valhalla-local ghcr.io/gis-ops/docker-valhalla/valhalla


docker build . -f Dockerfile.local --tag valhalla-local
# docker tag valhalla-local "phamidko/valhalla:latest"
# docker push "phamidko/valhalla:latest"

docker run -dt -p 8002:8002 -e tile_urls=https://download.geofabrik.de/north-america/canada/ontario-latest.osm.pbf --name valhalla-local valhalla-local
docker logs -f valhalla-local

curl http://localhost:8002/route \
--data '{"locations":[
              {"lat":41.318818,"lon":19.461336},
              {"lat":41.321001,"lon":19.459598}
           ],
         "costing":"auto"
        }' | jq '.'

docker exec -it valhalla-local bash

Create the embedded bundle image

In docker-compose.yml, modify the region pbf varible to compute different region tiles

docker compose build valhalla

docker run -dt --rm -p 8002:8002 --name valhalla-bundle valhalla-bundle

docker tag valhalla-bundle "phamidko/valhalla-bundle-ontario:latest"
docker push "phamidko/valhalla-bundle-ontario:latest"

GTFS static feed inject to burdle-image

first, download GTFS zip file from remtoe link and unzip the file GRT Open Data

Docker volume mount method

Mount the folder to docker run cmd Build Valhalla with transit

cd /home/phamid/upwork-repos/upwork-valhala
mkdir -p gtfs_feeds/grt_ontario
wget -O gtfs_feeds/grt_ontario/GRT_GTFS.zip https://www.regionofwaterloo.ca/opendatadownloads/GRT_GTFS.zip
unzip gtfs_feeds/grt_ontario/GRT_GTFS.zip -d gtfs_feeds/grt_ontario/


docker run -dt --rm -v ./gtfs_feeds:/gtfs_feeds -p 8002:8002 --name valhalla-bundle valhalla-bundle
docker exec -it valhalla-bundle /bin/bash


curl http://localhost:8002/route \
--data '{"locations":[
{"lat":43.47936690284358,"lon": -80.51799122219329},
{"lat":43.47239517859761,"lon":-80.59289294228155}
],
"costing":"multimodal"
}' | jq '.'

Docker-compose method

Purpose: Copy gtfs folder into the image so that there is no dependency in Azure Container App

docker compose build valhalla-transit --progress plain --no-cache

# check the contents
docker run -dt --rm -p 8002:8002 --name valhalla-transit-bundle valhalla-transit-bundle:latest
docker exec -it valhalla-transit-bundle bash
ls /gtfs_feeds

docker tag valhalla-transit-bundle "phamidko/valhalla-transit-bundle:latest"
docker push "phamidko/valhalla-transit-bundle:latest"

Usage (Azure Container App)

Define tile_urls environment for region pbf url link(s)
Set port binding to 8002

GTFS feed
