How to run valhalla with docker compose correctly?

[Unrepentant-Atheist]

So I managed to get my valhalla instance running with docker compose with this

---
version: "3.9"
services:
  snippet-box:
    image: valhalla/valhalla:run-latest
    container_name: valhalla
    restart: unless-stopped
    command:
      - /bin/bash
      - -c
      - |
        wget http://download.geofabrik.de/europe/switzerland-latest.osm.pbf http://download.geofabrik.de/europe/liechtenstein-latest.osm.pbf
        mkdir -p valhalla_tiles
        valhalla_build_config --mjolnir-tile-dir ${PWD}/valhalla_tiles --mjolnir-tile-extract ${PWD}/valhalla_tiles.tar --mjolnir-timezone ${PWD}/valhalla_tiles/timezones.sqlite --mjolnir-admin ${PWD}/valhalla_tiles/admins.sqlite > valhalla.json
        valhalla_build_tiles -c valhalla.json switzerland-latest.osm.pbf liechtenstein-latest.osm.pbf
        valhalla_build_extract -c valhalla.json -v
        valhalla_service valhalla.json 1
    ports:
      - 8002:8002
    volumes:
      - map-data:/valhalla_tiles
volumes:
  map-data:
networks:
  default:
    name: valhallanet
    external: true

However, I noticed: What if the container shuts down and needs to be restarted? Then the whole process of downloading and rebuilding the tiles happens again, even though the tiles are already in the volume: map-data. How can I tweak this docker-compose.yml to reflect that?

I have no problem running 2 different docker-compose.yml, one for building the tiles like that, the other to just start the service again with access to map-data.

How do?

I'm thinking I have to put the > valhalla.json inside valhalla_tiles and do

    command:
      - /bin/bash
      - -c
      - |
         valhalla_build_extract -c /valhalla_tiles/valhalla.json -v
         valhalla_service /valhalla_tiles/valhalla.json 1

or something like that in a different docker-compose.yml. I dunno.

tons of strategies. for starters, you could check if valhalla_tiles.tar exists, if so, skip building. or compare timestamps or or or.. you could also just use our image: https://github.com/gis-ops/docker-valhalla. it supports most use cases quite well. the documentation is comprehensive.

fwiw, IMO no need to open 4 different tickets, basically asking all about docker setups. bit too spaghetti for a public forum

That solved it, easiest way is

version: '3.3'
services:
    valhalla:
        container_name: valhalla
        image: 'gisops/valhalla:latest'
        volumes:
            - custom_files:/custom_files
        ports:
            - 8002:8002
        environment:
          - tile_urls=http://download.geofabrik.de/europe/switzerland-latest.osm.pbf http://download.geofabrik.de/europe/liechtenstein-latest.osm.pbf
          - server_threads=2  # determines how many threads will be used to run the valhalla server
          - use_tiles_ignore_pbf=True  # load existing valhalla_tiles.tar directly
          - build_elevation=False  # build elevation with "True" or "Force": will download only the elevation for areas covered by the graph tiles
          - build_admins=False  # build admins db with "True" or "Force"
          - build_time_zones=False  # build timezone db with "True" or "Force"
          - build_tar=True  # build an indexed tar file from the tile_dir for faster graph loading times
          - force_rebuild=False  # forces a rebuild of the routing tiles with "True"
volumes:
  custom_files:
networks:
  default:
    name: valhallanet
    external: true

with env variables! Much obliged!

hello, I am training to install the "Valhalla" route calculation engine locally under docker under virtualbox using ubuntu commands.
I followed the following steps:

• create the file: gisops_docker using the command: mkdir ~ / gisops_docker && cd $ _
• in this same folder I created the folder: custom_files using the same command.
• in the folder: custom_files I created the folder: docker-compose using the same command.
• in the folder: custom_files I downloaded the data "algeria-latest.osm.pbf" using the following command: Wget https://download.geofabrik.de/africa/Algeria-latest.osm.pbf
• then I entered the following path: gisops_docker / custom_files / docker-compose in order to create the file: docker-compose.yml by typing the command: sudo nano docker-compose.yml.
• once entered in the docker-compose.yml file I assigned the lines that are in the template in the link is the following: https://github.com/gis-ops/docker-valhalla/blob/master/ docker-compose.yml.template
  my question is that I can't save it, the only solution was to exit but I will end up with a docker-compose.yml file with padlock icon.
  So I haven't been able to get the "Valhalla" route planner to work.
  can you help me to make it work by giving me the exact steps in order to follow them correctly.
  awaiting a favorable response, please receive my most respectful greetings.

you somewhat landed in the wrong repo, this is a better place: https://github.com/gis-ops/docker-valhalla/discussions

I can't really follow what you did, but the instructions in the README are pretty concise. anyways, I just added a few more lines to the first code block, so try this: https://github.com/gis-ops/docker-valhalla

add more valhalla runtime options using env vars (you might not want to use all the extras): https://github.com/gis-ops/docker-valhalla#environment-variables

Hello,
Thank you sir nilsnolde for answering me, I followed the lines in the link: https://github.com/gis-ops/docker-valhalla while when I type the following line: docker run -dt - name valhalla_gis-ops -p 8002: 8002 -v $ PWD / custom_files: / custom_files gisops / valhalla: latest

I will have the following answer :

docker: Error response from daemon: Conflict. The container name "/ valhalla_gis-ops" is already in use by container "Oc1bOb78b5afb5ef9f2786391Ofaa4d7e51bf6b2969b5b7e3e029c9bac062d0". you have to remove (or rename) that container to be able to reuse that name.

The same, when I type the following instruction:
docker run -dt --name valhalla_gis-ops -p 8002: 8002 -v $ PWD / custom_files: / custom_files -e tile_urls = https: //download.geofabrik.de/europe/andorra-latest.osm.pbf gisops / valhalla : latest

I will have as an answer :

docker: Error response from daemon: Conflict. The container name "/ valhalla_gis-ops" is already in use by container "Oc1bOb78b5afb5ef9f2786391Ofaa4d7e51bf6b2969b5b7e3e029c9bac062d0". you have to remove (or rename) that container to be able to reuse that name.

In which case you advise me what to do if I did not understand the error message. I looked for these containers in order to either delete them or rename them although I did not find it, what to do in this case really I got stuck and this work I have to file soon.

Awaiting a favorable response, please receive my most distinguished greetings.

docker rm Oc1bOb78b5afb5ef9f2786391Ofaa4d7e51bf6b2969b5b7e3e029c9bac062d0

I don’t understand why you keep inserting spaces everywhere.. that’s not how command line works..

Please, ask someone you know to help you, this is way too basic to be covered here. Those are questions for stackoverflow or so, not for a project specific discussion forum that’s supposed to be helpful for people looking for project-specific problems. Shell syntax is not one of them.
