Pelias in Docker

This repository contains a framework for downloading/preparing and building the Pelias Geocoder using Docker and Docker Compose.

Projects

Example projects are included in the projects directory.

We recommend you start with the

portland-metro

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.

Prerequisites

You will need to have a modern version of

docker

docker-compose

This project supports Linux and Mac OSX operatings systems. Windows is currently not supported.

Permissions

In order to ensure security, Pelias docker containers, and the

pelias

Be sure you are running as a non-root user and that this user can execute

docker

Requirements for Linux

• Install

  util-linux

  using your distribution's package manager
  • Alpine Linux:

    sudo apk add util-linux

  • Debian/Ubuntu:

    sudo apt-get install util-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

  .

System requirements

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

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

You can find the

pelias

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:

which pelias

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

/usr/local/bin

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.

Configure Environment

The

pelias

.env

If this is your first time, you should change directories to an example project before continuing:

cd projects/portland-metro

Ensure that your current working directory contains the files:

.env

docker-compose.yml

pelias.json

Variable: DATA_DIR

The only mandatory variable in

.env

DATA_DIR

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:

mkdir /tmp/pelias

Then use your text editor to modify the

.env

COMPOSE_PROJECT_NAME=pelias
DATA_DIR=/tmp/pelias

You can then list the environment variables to ensure they have been correctly set:

pelias system env

Variables: COMPOSE_*

The compose variables are optional and are documented here: https://docs.docker.com/compose/env-file/

Note: changing the

COMPOSE_PROJECT_NAME

pelias/dockerfiles

COMPOSE_PROJECT_NAME=dockerfiles

Variable: DOCKER_USER

This variable is no longer used, and will be ignored. If you still have it in your

.env

Compose commands

The compose commands are available as a shortcut to running

docker-compose

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)

Download commands

The download commands will fetch and update geographic data from source.

For example:

pelias download tiger

DATA_DIR

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

Prepare commands

The prepare commands are used to run any commands which are required to setup/configure or build microservices.

For example:

pelias prepare interpolation

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

Elastic commands

The elastic commands control starting/stopping/configuring elasticsearch.

The special

pelias elastic wait

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

Import commands

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

System commands

The system commands help debug issues with incorrectly set environment variables.

The

pelias system update

pelias

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

Test command

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

Example queries

Once all the importers have completed and the Pelias services are running, you can make queries against your new Pelias build:
