  1. follow the Docker instructions

  2. create the jobs directories

    mkdir -p /home/jobs/scripts/by-user/root/docker/osm-tile-server
mkdir -p /home/jobs/services/by-user/root

  3. create the directories for the volumes

    mkdir -p /data/DOCKER_VOLUMES/openstreetmap-tile-server/db
mkdir -p /data/DOCKER_VOLUMES/openstreetmap-tile-server/openstreetmap-rendered-tiles

  4. database must be at least on SSDs to have decent performance, even better if they are on RAID 0. The faster the better: multiple fast NVME drives on RAID 0 with a fast filesystem for flash memory, such as F2FS, would be the best option.

    If a disk breaks you can swap it and re-import the maps since it’s not vital data.

    Mount the filesystems on the SSDs on /data/DOCKER_VOLUMES/openstreetmap-tile-server/db.

    I didn’t see any performace hit in putting the cache on normal HDDs. Put the cache in /data/DOCKER_VOLUMES/openstreetmap-tile-server/openstreetmap-rendered-tiles.

    Nota

    Importing Italy, for example, takes aroung 50GB of space for the database

  5. download the pbf and poly files from geofabrik.de

    cd /data/DOCKER_VOLUMES/openstreetmap-tile-server
wget https://download.geofabrik.de/europe/italy-latest.osm.pbf
wget https://download.geofabrik.de/europe/italy.poly
https://download.geofabrik.de/europe/italy-latest.osm.pbf.md5
md5sum --check

  6. change permissions on the cache directory so that Docker can mount it in the container

    chown 1000:1000 /data/DOCKER_VOLUMES/openstreetmap-tile-server/openstreetmap-rendered-tiles

  7. create a Docker compose file

    /home/jobs/scripts/by-user/root/docker/openstreetmap-tile-server/docker-compose.yml#
     1version: '3.7'

 3services:

 8    ports:

23  import:
24    image: overv/openstreetmap-tile-server:v1.8.2
25    # Do not start when using "docker-compose up".

40      - /data/media/DOCKER_VOLUMES/openstreetmap-tile-server/italy.poly:/data.poly
41    command: "import"

  8. import the data in the database. This operation takes a long time

    cd /home/jobs/scripts/by-user/root/docker/osm-tile-server
docker-compose up import

  9. create a Systemd unit file. See also the Docker compose services section

    /home/jobs/services/by-user/root/docker-compose.openstreetmap-tile-server.service#
     1[Unit]
 2Requires=docker.service

17WantedBy=multi-user.target

  10. fix the permissions

    chmod 700 /home/jobs/scripts/by-user/root/docker/osm-tile-server
chmod 700 -R /home/jobs/services/by-user/root

  11. run the deploy script

  12. connect to http://127.0.0.1:4006 with a JavaScript supported browser. You should see a full screen planet map.

    Rendering is very slow the first time.

    Try zooming into a zone and wait until it’s fully rendered. Reload the browser page with CTRL+shift+R and go to the same zone. This time the rendering should be istantaneous

  13. Add a virtual host in your webserver configuration using port 4006 as reverse proxy
