A modular, open-source search engine for our world.
Pelias is a geocoder powered completely by open data, available freely to everyone.
What is Pelias?
Pelias is a search engine for places worldwide, powered by open data. It turns addresses and place names into geographic coordinates, and turns geographic coordinates into places and addresses. With Pelias, you’re able to turn your users’ place searches into actionable geodata and transform your geodata into real places.
We think open data, open source, and open strategy win over proprietary solutions at any part of the stack and we want to ensure the services we offer are in line with that vision. We believe that an open geocoder improves over the long-term only if the community can incorporate truly representative local knowledge.
Pelias in Docker
Example projects are included in the projects directory.
We recommend you start with the
portland-metro example as a first-time user: it has lower disk and time requirements and can be used to help you familiarize yourself with the process.
Once you have successfully completed a small build you can use this as a base to create your own projects or move on to larger projects.
This project supports Linux and Mac OSX operatings systems. Windows is currently not supported.
In order to ensure security, Pelias docker containers, and the
pelias helper script, will not run as a root user!
Be sure you are running as a non-root user and that this user can execute
docker commands. See the Docker documentation article Manage Docker as a non-root user to do this.
Requirements for Linux
util-linuxusing your distribution's package manager
- Alpine Linux:
sudo apk add util-linux
sudo apt-get install util-linux
- Alpine Linux:
Requirements for Mac OSX
- install GNU coreutils with Homebrew:
brew install coreutils.
- Max-out Docker computing resources(
Memory-RAM and CPUs-Cores) dedicated to Docker in
Docker > Preferences > Advanced.
Scripts can easily download tens of GB of geographic data, so ensure you have enough free disk space!
At least 8GB RAM is required.
How long will it take?
You should be able to get started with the default Portland-metro area build in under an hour with a fast internet connection.
On a machine with ~32 CPU cores, a full planet build can be done in under a day with the right settings.
The interpolation build (
pelias prepare interpolation), which is single threaded will take 6+ days
for the full planet. We generally recommend skipping it when you are first
For more info on time estimates and hardware requirements for large build see our full planet considerations documentation.
Quickstart build script
The following shell script can be used to quickly get started with a Pelias build.
#!/bin/bash set -x # change directory to the where you would like to install Pelias # cd /path/to/install # clone this repository git clone https://github.com/pelias/docker.git && cd docker # install pelias script # this is the _only_ setup command that should require `sudo` sudo ln -s "$(pwd)/pelias" /usr/local/bin/pelias # cd into the project directory cd projects/portland-metro # create a directory to store Pelias data files # see: https://github.com/pelias/docker#variable-data_dir # note: use 'gsed' instead of 'sed' on a Mac mkdir ./data sed -i '/DATA_DIR/d' .env echo 'DATA_DIR=./data' >> .env # run build pelias compose pull pelias elastic start pelias elastic wait pelias elastic create pelias download all pelias prepare all pelias import all pelias compose up # optionally run tests pelias test run
Installing the Pelias helper script
This repository makes use of a helper script to make basic management of the Pelias Docker images easy.
If you haven't done so already, you will need to ensure the
pelias command is available on your path.
You can find the
pelias file in the root of this repository.
Advanced users may have a preference how this is done on their system, but a basic example would be to do something like:
# change directory to the where you would like to install Pelias # cd /path/to/install # clone this repository git clone https://github.com/pelias/docker.git && cd docker # install pelias script sudo ln -s "$(pwd)/pelias" /usr/local/bin/pelias
Once the command is correctly installed you should be able to run the following command to confirm the pelias command is available on your path:
Resolving PATH issues
If you are having trouble getting this to work then quickly check that the target of the symlink is listed on your $PATH:
tr ':' '\n' <<< "$PATH"
If you used the
ln -s command above then the directory
/usr/local/bin should be listed in the output.
If the symlink target path is not listed, then you will either need to add its location to your $PATH or create a new symlink which points to a location which is already on your $PATH.
pelias command looks for an
.env file in your current working directory, this file contains information specific to your local environment.
If this is your first time, you should change directories to an example project before continuing:
Ensure that your current working directory contains the files:
pelias.json before continuing.
The only mandatory variable in
This path reflects the directory Pelias will use to store downloaded data and use to build it's other microservices.
You must create a new directory which you will use for this project, for example:
Then use your text editor to modify the
.env file to reflect your new path, it should look like this:
You can then list the environment variables to ensure they have been correctly set:
pelias system env
The compose variables are optional and are documented here: https://docs.docker.com/compose/env-file/
Note: changing the
COMPOSE_PROJECT_NAME variable is not advisable unless you know what you are doing. If you are migrating from the deprecated
pelias/dockerfiles repository then you can set
COMPOSE_PROJECT_NAME=dockerfiles to enable backwards compatibility with containers created using that repository.
This variable is no longer used, and will be ignored. If you still have it in your
.env file, you can safely remove it.
The following is a list of all supported CLI commands.
$ pelias Usage: pelias [command] [action] [options] compose pull update all docker images compose logs display container logs compose ps list containers compose top display the running processes of a container compose exec execute an arbitrary docker-compose command compose run execute a docker-compose run command compose up start one or more docker-compose service(s) compose kill kill one or more docker-compose service(s) compose down stop all docker-compose service(s) download wof (re)download whosonfirst data download oa (re)download openaddresses data download osm (re)download openstreetmap data download tiger (re)download TIGER data download transit (re)download transit data download all (re)download all data elastic drop delete elasticsearch index & all data elastic create create elasticsearch index with pelias mapping elastic start start elasticsearch server elastic stop stop elasticsearch server elastic status HTTP status code of the elasticsearch service elastic wait wait for elasticsearch to start up elastic info display elasticsearch version and build info elastic stats display a summary of doc counts per source/layer import wof (re)import whosonfirst data import oa (re)import openaddresses data import osm (re)import openstreetmap data import polylines (re)import polylines data import transit (re)import transit data import csv (re)import csv data import all (re)import all data prepare polylines export road network from openstreetmap into polylines format prepare interpolation build interpolation sqlite databases prepare placeholder build placeholder sqlite databases prepare all build all services which have a prepare step system check ensure the system is correctly configured system env display environment variables system update update the pelias command by pulling the latest version
The compose commands are available as a shortcut to running
docker-compose directly, they will also ensure that your environment is correctly configured.
See the docker-compose documentation for more info: https://docs.docker.com/compose/overview/
pelias compose pull update all docker images pelias compose logs display container logs pelias compose ps list containers pelias compose top display the running processes of a container pelias compose exec execute an arbitrary docker-compose command pelias compose run execute a docker-compose run command pelias compose up start one or more docker-compose service(s) pelias compose kill kill one or more docker-compose service(s) pelias compose down stop all docker-compose service(s)
The download commands will fetch and update geographic data from source.
pelias download tiger will fetch street data from the US Census Bureau and store it in the directory referenced by the
DATA_DIR environment variable.
pelias download wof (re)download whosonfirst data pelias download oa (re)download openaddresses data pelias download osm (re)download openstreetmap data pelias download tiger (re)download TIGER data pelias download transit (re)download transit data pelias download all (re)download all data
The prepare commands are used to run any commands which are required to setup/configure or build microservices.
pelias prepare interpolation will build a street address interpolation index.
Note: the order of execution is important, the prepare commands require data, so they must be run after the download commands have fetched the data.
pelias prepare polylines export road network from openstreetmap into polylines format pelias prepare interpolation build interpolation sqlite databases pelias prepare placeholder build placeholder sqlite databases pelias prepare all build all services which have a prepare step
The elastic commands control starting/stopping/configuring elasticsearch.
pelias elastic wait command can be used in scripts to block the script execution until elasticsearch is ready to accept connections.
pelias elastic drop delete elasticsearch index & all data pelias elastic create create elasticsearch index with pelias mapping pelias elastic start start elasticsearch server pelias elastic stop stop elasticsearch server pelias elastic status HTTP status code of the elasticsearch service pelias elastic wait wait for elasticsearch to start up pelias elastic info display elasticsearch version and build info pelias elastic stats display a summary of doc counts per source/layer
The import commands import source data in to elasticsearch.
pelias import wof (re)import whosonfirst data pelias import oa (re)import openaddresses data pelias import osm (re)import openstreetmap data pelias import polylines (re)import polylines data pelias import transit (re)import transit data pelias import all (re)import all data
The system commands help debug issues with incorrectly set environment variables.
pelias system update command can be used to ensure that the
pelias command itself is up-to-date by pulling the latest source code from Github.
pelias system check ensure the system is correctly configured pelias system env display environment variables pelias system update update the pelias command by pulling the latest version
The test command runs the fuzzy-tester tests against any test cases in your project.
test run run fuzzy-tester test cases
Optionally cleanup temporary files
Once the build is complete, you can cleanup temporary files that are no longer useful. The numbers in this snippet below are rough estimates for a full planet build.
# These folders can be entirely deleted after the import into elastic search rm -rf /data/openaddresses #(~43GB) rm -rf /data/tiger #(~13GB) rm -rf /data/openstreetmap #(~46GB) rm -rf /data/polylines #(~2.7GB) # Within the content of the "interpolation" folder (~176GB) we must # preserve "street.db" (~7GB) and "address.db" (~25GB), the rest can be deleted cd /data/interpolation rm -rf -- !("street.db"|"address.db") # Within the content of the "placeholder" folder (~1.4GB), we must # preserve the "store.sqlite3" (~0.9GB) file, the rest can be deleted cd /data/placeholder rm -rf -- !("store.sqlite3")
View status of running containers
Once the build is complete, you can view the current status and port mappings of the Pelias docker containers:
pelias compose ps
View logs and debug errors
You can inspect the container logs for errors by running:
pelias compose logs
Once all the importers have completed and the Pelias services are running, you can make queries against your new Pelias build:
