#Docker-OSM
|
||||
|
||||
## Usage
|
||||
|
||||
In this example we will set up an OSM database for South Africa that
|
||||
will pull for updates every 2 minutes.
|
||||
|
||||
First fetch the latest South Africa osm binary dump file (.pbf) and state file.
|
||||
I will write the example as generically as possible so that you can substitute
|
||||
your own country or region here.
|
||||
|
||||
```
|
||||
cd osm_pbf
|
||||
wget -c -O country.pbf http://download.openstreetmap.fr/extracts/africa/south_africa.osm.pbf
|
||||
wget -c -O country.state.txt http://download.openstreetmap.fr/extracts/africa/south_africa.state.txt
|
||||
wget -c -O polygon.poly http://download.geofabrik.de/africa/south-africa-and-lesotho.poly
|
||||
```
|
||||
|
||||
or you can use the PBF downloader using Geofabrik.
|
||||
To get the list of available countries in Geofabrik :
|
||||
First get the list of available countries in Geofabrik :
|
||||
``python pbf_downloader.py list``
|
||||
|
||||
Now fetch the latest South Africa osm binary dump file (.pbf) and state files:
|
||||
|
||||
You can download a country or a continent :
|
||||
``python pbf_downloader.py south-africa-and-lesotho``
|
||||
|
||||
The script will download the PBF file, the state file and the polygon for clipping.
|
||||
|
||||
As an alternative to the above (not all countries are available from geofabrik), you
|
||||
can also fetch the pbf from another site such as shown in the example below which
|
||||
will fetch the latest South Africa osm binary dump file (.pbf) and state file from
|
||||
the French openstreetmap site. Note that you need the ```wget``` command line
|
||||
application installed on your computer to follow the instructions below.
|
||||
|
||||
```
|
||||
cd settings
|
||||
wget -c -O country.pbf http://download.openstreetmap.fr/extracts/africa/south_africa.osm.pbf
|
||||
wget -c -O country.state.txt http://download.openstreetmap.fr/extracts/africa/south_africa.state.txt
|
||||
wget -c -O polygon.poly http://download.geofabrik.de/africa/south-africa-and-lesotho.poly
|
||||
```
|
||||
|
||||
You can also visit the http://download.openstreetmap.fr/extracts/ site and
|
||||
download the extract you want manually using your browser.
|
||||
|
||||
|
||||
Now build the docker images needed to run the application:
|
||||
|
||||
```
|
||||
docker-compose build
|
||||
docker-compose up
|
||||
```
|
||||
|
||||
In production you should daemonize the services when bringing them up:
|
||||
|
||||
```
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
## Docker OSM Update
|
||||
|
||||
