OSRM cookbook

This cookbook can do the following things for you

• Install and configure the OSRM route daemon
• Download, extract, prepare map data and keep them up to date
  • (Uses the map data from Geofabrik)

To use the following recipes and providers, add the following to your metadata.rb

depends 'osrm'

Recipes

default

Runs install_git

install_git

Clone and install the latest HEAD from Project-OSRM to node['osrm']['target'] (default /opt/osrm).

Providers

osrm_map

osrm_map is a shortcut that calls the other map providers in the following order

• osrm_map_download
• osrm_map_extract
• osrm_prepare

This example downloads, extracts and prepares the osrm map for Germany:

osrm_map 'germany'

The following additional attributes are allowed:

osrm_map 'europe'
  path            '/srv/my_map_data'  # Use the same directory you used in osrm_map_download)
  profile         'car'               # Profile to use (defaults to 'car')
  profile_dir     '/srv/my_profiles'  # Where to look for profiles (.lua files)
  extract_command 'osrm-extract'      # Path to osrm-extract binary
  prepare_command 'osrm-prepare'      # Path to osrm-prepare binary
  user            'my_osrm_user'      # User to run commands as
  cwd             '/srv/my_osrm'      # Set working directory for osrm-extract
  threads         5                   # How many threads to use (defaults to number of cpu cores)
  memory          4                   # How many GB of memory to use (defaults to system memory - 1GB)
  cleanup         false               # Do not cleanup .osrm and .osrm.restrictions after preparing
  timeout         3600                # Timeout in seconds for osrm-extract/osrm-prepare. Defaults to 24h
  stxxl_size      150000              # Size (in MB) of stxxl temporary file. Dynamically allocated by default
  stxxl_file      '/tmp/stxxl'        # Location of stxxl temporary file. Defaults to '/var/tmp/stxxl'

  # The files checksum can also be checked (defaults to true)
  # When set to true, it will use the default checksum set in the attributes (if existent)
  # When set to false, it doesn't check the checksum
  # When set to an ftp:// or http:// URL, retrieve the file and use the checksum in its content
  # When set to a string, use it as the checksum
  checksum        'http://url.to/checksum.md5'

  action :create_if_missing           # :create and :create_if_missing are supported
end

osrm_map_download

Downloads map data for the specified region.

osrm_map_download 'planet'
osrm_map_download 'europe'
osrm_map_download 'north-america'
osrm_map_download 'germany'
osrm_map_download 'us-west'

For a full list of supported regions, take a look at attributes/regions.rb. If necessary, it can be easily extended to support even more, feel free to file a pull request!

By default, the provider automatically re-downloads the file if it was changed on the server. You can prevent this behaviour when using the :download_if_missing action:

osrm_map_download 'europe' do
  action :download_is_missing
end

Furthermore, you can specify the following attributes:

osrm_map_download 'us-west' do
  user 'my_osrm_user'
  path '/srv/my_map_data'

  # The files checksum can also be checked (defaults to true)
  # When set to true, it will use the default checksum set in the attributes (if existent)
  # When set to false, it doesn't check the checksum
  # When set to an ftp:// or http:// URL, use its contents as a checksum
  # When set to a string, use it as the checksum
  checksum        'http://url.to/checksum.md5'
end

osrm_map_extract

Extracts downloaded map data, using osrm-extract.

Example:

osrm_map_extract 'europe'

The following attributes are supported

osrm_map_extract 'europe' do
  path        '/srv/my_map_data'  # Use the same directory you used in osrm_map_download)
  profile     'car'               # Profile to use (defaults to 'car')
  profile_dir '/srv/my_profiles'  # Where to look for profiles (.lua files)
  command     'osrm-extract'      # Binary to use
  user        'my_osrm_user'
  cwd         '/srv/my_osrm'      # Set working directory for osrm-extract
  threads     5                   # How many threads to use (defaults to number of cpu cores)
  memory      4                   # How many GB of memory to use (defaults to system memory - 1GB)
  timeout     3600                # Timeout in seconds for osrm-extract. Defaults to 24h
  stxxl_size  150000              # Size (in MB) of stxxl temporary file. Dynamically allocated by default
  stxxl_file  '/tmp/stxxl'        # Location of stxxl temporary file. Defaults to '/var/tmp/stxxl'
end

osrm_map_prepare

Prepares extracted map data, using osrm-prepare.

Example:

osrm_map_prepare 'europe'

The following attribtues are supported:

osrm_map_prepare 'europe' do
  path        '/srv/my_map_data'  # Use the same directory you used in osrm_map_download)
  profile     'car'               # Profile to use (defaults to 'car')
  profile_dir '/srv/my_profiles'  # Where to look for profiles (.lua files)
  command     'osrm-prepare'      # Binary to use
  user        'my_osrm_user'
  cwd         '/srv/my_osrm'      # Set working directory for osrm-prepare
  threads     5                   # How many threads to use (defaults to number of cpu cores)
  cleanup     false               # Do not cleanup .osrm and .osrm.restrictions after preparing
  timeout     3600                # Timeout in seconds for osrm-extract. Defaults to 24h
end

osrm_routed

Sets up and starts osrm-routed (using upstart) for the specified region

Example:

osrm_routed 'europe'

The following attributes are supported:

osrm_routed 'europe' do
  config_dir   '/etc/osrm-routed'
  service_name 'osrm-routed-%s'    # %s will be replaced with the selected region and profile

  profile      'car'               # Profile for which to start the daemon

  user         'osrm-routed'       # User to run the daemon as (will be created if not existent)
  home         '/my/osrm-install'  # Home directory of the osrm-routed user

  daemon       '/path/to/osrm-routed'

  threads      16                  # How many threads to use (defaults to number of cpu cores)

  port         5000                # TCP port to bind to
  listen       '127.0.0.1'         # TCP address to listen on
end

Attributes

You can set the following attributes if you need settings that differ form the defaults

default

node['osrm']['repository'] = 'git://github.com/DennisOSRM/Project-OSRM.git'
node['osrm']['branch'] = 'master' # use e.g. 'v0.3.5' for a stable version

node['osrm']['target'] = '/opt/osrm'
node['osrm']['map_path'] = '/opt/osrm-data'

# use system memory - 1GB by default
node['osrm']['memory'] = node['memory']['total'].to_i / 1024 / 1024 - 1
node['osrm']['threads'] = node['cpu']['total']

routed

node['osrm']['routed']['user'] = 'osrm-routed'
node['osrm']['routed']['service_name'] = 'osrm-routed-%s'
node['osrm']['routed']['config_dir'] = '/etc/osrm-routed'

regions

You can add custom regions like this

node['osrm']['map_data']['your-region']['profiles'] = %w{car}
node['osrm']['map_data']['your-region']['url'] = "http://download.geofabrik.de/your-region-latest.osm.pbf"
node['osrm']['map_data']['your-region']['checksum'] = "#{node['osrm']['map_data']['your-region']['url']}.md5"
