Use multiple files to build graphs in a docker instance

openrouteservice
1

I successfully run an instance of open route service on docker (using a Frrance osm pbf file) for a few months, and I would want to modify it to add a few neighbouring countries or provinces.

Everything I find in the documentation and github only points to a single osm file designed with the environment variable OSM_FILE.

I was not able to pinpoint where and when in the code the graphs are generated so I can’t infer if I can modify anything to have OSM_FILE (or another variable) point to a list or a whole directory of osm files.

Could you please provide some advice ? Thanks in advance.

Hey,

the openrouteservice is not able to process multiple osm-files at once. Please use any other OSM tooling (osmium, osmosis, …) to merge all your .pbf-files into one, and use this to run the openrouteservice.

Best regards

Thank you very much for your answer, osmosis it is then :wink:

For reference here is the part of my docker-entrypoint shell file to download & merge pbfs

if [ "$BUILD_GRAPHS" = "True" ] || [ ! -f "/ors-core/data/osm_file.pbf" ]; then
  echo "Downloading and processing pbf files"
  rm -f "/ors-core/data/osm_file.pbf"
  rm -rf ${graphs}*
  for osm_file in "${osm_list[@]}"
  do
    filename="${osm_file_path}${osm_file}"
    echo "Processing ${osm_file}"
    echo "Downloading from ${osm_gfb}${osm_file}-latest.osm.pbf..." >> ${log_path}${osm_file}.log 2>&1
    while true; do
      wget --output-document="${filename}.osm.pbf" "${osm_gfb}${osm_file}-latest.osm.pbf" >> ${log_path}${osm_file}.log 2>&1
      computed_md5=$(md5sum "${filename}.osm.pbf" | awk '{ print $1 }')
      wget --output-document="${filename}.osm.pbf.md5" "${osm_gfb}${osm_file}-latest.osm.pbf.md5" >> ${log_path}${osm_file}.log 2>&1
      expected_md5=$(cat "${filename}.osm.pbf.md5" | awk '{ print $1 }')
      if [[ "$computed_md5" == "$expected_md5" ]]; then
        echo "File successfully downloaded and verified." >> ${log_path}${osm_file}.log 2>&1
        rm "${filename}.osm.pbf.md5"
        break
      else
        echo "MD5 checksum mismatch. Redownloading the file..." >> ${log_path}${osm_file}.log 2>&1
        rm "${filename}.osm.pbf.md5" "${filename}.osm.pbf"
      fi
    done
    if [ $? -ne 0 ]; then
        echo "Error: Failed to download the file." >> ${log_path}${osm_file}.log 2>&1
        exit 1
    fi
    if [ ! -f "/ors-core/data/osm_file.pbf" ]; then
      echo "sorting file" >> ${log_path}${osm_file}.log 2>&1
      osmium sort --strategy="multipass" -v -o "${filename}-sorted.osm.pbf" "${filename}.osm.pbf" >> ${log_path}${osm_file}.log 2>&1
      echo "creating file /ors-core/data/osm_file.pbf" >> ${log_path}${osm_file}.log 2>&1
      mv "${filename}-sorted.osm.pbf" "/ors-core/data/osm_file.pbf"
    else
      echo "sorting file" >> ${log_path}${osm_file}.log 2>&1
      osmium sort --strategy="multipass" -v -o "${filename}-sorted.osm.pbf" "${filename}.osm.pbf" >> ${log_path}${osm_file}.log 2>&1
      echo "merging file on /ors-core/data/osm_file.pbf" >> ${log_path}${osm_file}.log 2>&1
      osmium merge -v "/ors-core/data/osm_file.pbf" "${filename}-sorted.osm.pbf" -o "/ors-core/data/osm_tmp.pbf" >> ${log_path}${osm_file}.log 2>&1
      mv "/ors-core/data/osm_tmp.pbf" "/ors-core/data/osm_file.pbf"
      rm -f "${filename}-sorted.osm.pbf"
    fi
  done
